Ovarian Cancer: Symptoms, Causes, Types, Stages, and Treatment Options

Introduction

Bloating, abdominal discomfort, or changes in the appetite in women may seem like digestive issues; however, if they are unusual for you and persist for longer than 2 weeks, they should be taken seriously. While these symptoms can have many causes, persistent or unusual changes may sometimes indicate ovarian cancer¹. This blog explores the common signs of ovarian cancer, risk factors, diagnosis and treatment of ovarian cancer, and can help you understand what to look out for and when to seek medical advice.

What Is Ovarian Cancer?

Ovarian cancer is a cancer that starts in the ovaries, two small organs in the female reproductive system that produce eggs and hormones². It develops when abnormal cells grow uncontrollably in the ovary and form a tumour³. Some ovarian cancers may start in the fallopian tubes (small tubes that connect the ovaries to the womb) or nearby peritoneal tissues⁴.

Symptoms of Ovarian Cancer

Although ovarian cancer cannot always be prevented, knowing the signs of ovarian cancer and recognising changes in your body can help you seek medical advice when needed. The common and possible ovarian cancer symptoms include^1,5:

Bloating or swelling in the abdomen
Pain or a feeling of pressure in the abdomen or pelvic area
Feeling full quickly or having difficulty eating
Needing to urinate more often or having a sudden urge to urinate
Constipation or other changes in bowel habits
Back pain
Unusual vaginal bleeding or discharge, especially after menopause

It is important to pay attention to symptoms that are new, persistent, occur more frequently than usual, or represent a noticeable change from your normal pattern.

Note: These symptoms may also be caused by conditions other than ovarian cancer and are not just ovarian cancer symptoms⁵.

Causes and Risk Factors of Ovarian Cancer

The exact cause of ovarian cancer is not exactly known. Several factors may increase the chance of developing ovarian cancer. Let’s have a look at ovarian cancer risk factors:

Genetic changes acquired during life: Changes in DNA that affect how cells grow and divide can lead to cancer. These can happen naturally during a person’s lifetime or due to environmental factors like UV ray exposure^2,3.
Inherited gene changes: These are genetic changes passed from a parent, e.g., changes in BRCA1 and BRCA2 genes that are associated with breast cancer⁶.
Older age: The risk generally increases as women get older, particularly after menopause⁶.
Family history: Having a close relative (like mother, aunt or sister) with ovarian cancer can increase the risk⁶.
Personal history of breast cancer: Having had breast, uterine, or colorectal cancer in the past increases the risk of ovarian cancer⁶.
Endometriosis: Women with endometriosis (in which the inner lining of the uterus grows on tissues/organs outside the uterus) may have a higher risk of developing ovarian cancer⁶.
Never having given birth: Women who have never given birth or have had difficulty conceiving may have a higher risk of ovarian cancer⁶.
Early first period: Starting menstruation at a younger age may be linked with a higher risk, as found in some studies⁷.
Late menopause: Going through menopause at an older age may increase risk⁷.
Hormone replacement therapy (HRT): Taking HRT may increase the risk⁷.
Being overweight: Higher body weight is associated with an increased risk of ovarian cancer⁷.
Smoking: Smoking is linked with some types of ovarian cancer⁷.
Certain reproductive or fertility factors: Some studies have found links between infertility and ovarian cancer⁸.

Note: Having one or more risk factors does not mean that a woman will develop ovarian cancer. Some women may develop the disease without having any known risk factors⁶.

Types of Ovarian Cancer

Ovarian cancer is grouped into different types depending on the cells where the cancer starts. The three main types are⁹:

1. Epithelial ovarian cancer

This is the most common type of ovarian cancer. It begins in the cells that form the outer covering of the ovary. The different types of epithelial ovarian cancer include^9,10:

Serous
Mucinous
Endometrioid
Clear cell
Transitional cell

2. Germ cell ovarian cancer

This is a less common type that starts in the cells that normally develop into eggs. It is more often found in teenagers and younger women⁹.

3. Stromal cell ovarian cancer

This rare type develops in the cells that support the ovary and help it produce hormones. It develops in the tissues that support the ovaries and may be diagnosed at an early stage⁹.

Together, these three groups make up most ovarian cancers. Some cancers found in the ovary may also have started in another part of the body and then spread to the ovary.

Ovarian Cancer Stages

Ovarian cancer is usually divided into four stages, based on how far it has spread⁵.

Stage 1: Cancer is found only in one or both ovaries or fallopian tubes.
- IA: Cancer is in one ovary or fallopian tube.
- IB: Cancer is in both ovaries or fallopian tubes.
- IC: Cancer is in one or both ovaries or fallopian tubes, with additional features such as rupture of the tumour or outer covering of the ovary or cancer cells in abdominal cavity or washings of the tissue lining this cavity.

Stage 2: Cancer is found in one or both ovaries or fallopian tubes and has spread to nearby organs within the pelvis or primary peritoneal cancer is found in the pelvis.
- IIA: Cancer has spread to the uterus and/or both ovaries or fallopian tubes.
- IIB: Cancer has spread to other organs in the pelvis, such as the colon.

Stage 3: Cancer is primary peritoneal cancer or is found in one or both ovaries or fallopian tubes and has spread outside the pelvis to the abdomen or nearby lymph nodes.
- IIIA1: Cancer has spread to nearby lymph nodes.
- IIIA2: There is spread to the abdominal lining outside the pelvis that can be only seen with a microscope.
- IIIB: Visible cancer deposits outside the pelvis are 2 cm or smaller.
- IIIC: Visible cancer deposits outside the pelvis are larger than 2 cm.

Stage 4: Cancer has spread to distant parts of the body, such as the lungs or liver.
- IVA: Cancer cells are found in the fluid that has built up around the lungs.
- IVB: Cancer has spread to distant organs or lymph nodes outside the abdomen.

Knowing the ovarian cancer stages helps doctors determine the right treatment options.

How Is Ovarian Cancer Diagnosed?

If a doctor suspects ovarian cancer, they may recommend a few tests for ovarian cancer diagnosis. These include:

Medical history: The doctor will ask about your symptoms, when they started, any previous health problems or treatments⁵, and whether ovarian or breast cancer has occurred in your family.
Physical and pelvic examination: The doctor may gently examine your abdominal and pelvic area to look for swelling, lumps or areas of discomfort and the size, shape, and position of the ovaries and uterus⁵.
Blood tests: A blood test may measure CA-125, a protein that may increase in ovarian cancer. However, CA-125 may also be high in conditions like endometriosis; therefore, CA-125 alone cannot diagnose or screen for ovarian cancer and is used along with other tests¹¹.
Ultrasound scan: An ultrasound scan uses sound waves to create images of the organs and tissues in the abdomen⁵ to check for any abnormalities. Transvaginal Ultrasound (TVS) is a key first-line imaging test when an ovarian or pelvic abnormality is suspected⁴.
CT scan: A CT scan can provide more detailed images of the inside of the body to confirm the diagnosis. A dye may be used during a CT scan to provide clearer images⁵^,12.
MRI or PET scan: These scans may sometimes be recommended to give doctors a clearer picture of the tumour¹³.
Biopsy or tissue testing: If needed, a small sample of tissue may be taken during surgery and examined under a microscope to check for cancer cells⁵^,12.
Laparoscopy : In some cases, a specialist may place a camera through a small cut on the abdomen to examine the area closely¹².
Laparotomy or Surgery: May also be done to remove some tissue or the ovaries¹².

Ovarian Cancer Treatment Options

Ovarian cancer treatment varies from person to person. It depends on the type and stage of the cancer, its location, whether it has spread, and the person’s overall health. A specialist team will discuss the most suitable treatment and what to expect⁵. The common options include:

1. Surgery

Surgery is a common treatment for ovarian cancer and aims to remove as much of the cancer as possible. Depending on the type and stage of the cancer, this may involve removing one or both ovaries, the fallopian tubes, the uterus, or nearby tissues.

2. Chemotherapy

Chemotherapy uses medicines to stop cancer cell growth by stopping them from multiplying or killing them. It may be given before or after surgery and can also be used if the cancer returns.

3. Targeted therapy

These medicines target specific cancer cells or other type of cells that help cancer cells grow. They may be offered to some people with advanced or recurrent ovarian cancer.

4. Radiotherapy

Radiotherapy uses high-energy radiation to destroy cancer cells. It is not usually the main treatment for ovarian cancer, but it may sometimes be used to control symptoms or treat cancer that has spread to another part of the body.

5. Immunotherapy

This treatment uses substances to boost or direct the body’s immune system to help fight cancer cells⁵.

6. Hormone therapy

Some of the ovarian cancers develop or grow using hormones such as estrogen. Hormone therapy may be used to block these hormones so that the cancer does not grow.

7. Treatment if the cancer returns

If ovarian cancer comes back, the treatment will depend on where it has returned, previous treatments and the person’s overall health. Options may include chemotherapy, targeted therapy, hormone therapy or further surgery¹⁴.

Not everyone will need all these treatments. The Gynaecologic oncology team will explore options available for each individual and, based on the possible benefits and side effects of each, will help the individual decide on the most suitable approach to remove as much of the cancer as possible (cytoreduction).

How to Prevent Ovarian Cancer?

There is no certain way to prevent ovarian cancer, but some steps may help lower its chance or help early diagnosis¹⁵. These include:

Know your family history: Tell your doctor if any of your close relatives have had ovarian or breast cancer, so that appropriate screening tests may be done¹⁵.
Consider genetic advice: If cancer runs in your family, your doctor may recommend genetic counselling or testing¹⁵.
Maintain a healthy weight: Being overweight is linked with a higher chance of ovarian cancer¹⁶.
Avoid smoking: Stopping smoking can help reduce the risk of several cancers¹⁶.
Discuss HRT with your doctor: Taking HRT after menopause is associated with increased risk of ovarian cancer. If you are currently taking HRT, speak to your doctor about the potential risks and further steps¹⁶.
Ask about contraception: Using oral contraceptive pills is associated with a lower risk of ovarian cancer. However, they should not be used solely for cancer prevention as they cannot prevent cancer completely¹⁷.
Certain surgeries: Some procedures, such as having the fallopian tubes tied (tubal ligation) or removing the fallopian tubes (salpingectomy), both ovaries (bilateral oophorectomy), or the uterus (and sometimes the cervix) may reduce the risk of ovarian cancer¹⁷.
Breastfeeding: Breastfeeding may slightly reduce the risk of ovarian cancer, particularly when breastfeeding continues for a longer period¹⁵.

No method can completely prevent ovarian cancer, so knowing the symptoms and getting unusual changes checked is important.

When to Consult a doctor?

Speak to your doctor if you notice symptoms such as the following that are unusual for you, last for 2 weeks or longer, become more frequent, or do not improve¹:

Persistent bloating or swelling of the tummy
Pelvic pain or pressure
Abdominal or back pain
Feeling full quickly or having difficulty eating
Needing to urinate more often or having an urgent need to urinate
Changes in bowel habits, such as constipation
Unusual vaginal bleeding or discharge, especially after menopause

These symptoms can have many causes and do not necessarily mean ovarian cancer. However, if they are unusual for you or persist, it is important to speak to your doctor.

Conclusion

Ovarian cancer may be hard to spot because its early signs can resemble common stomach or urinary problems. Being aware of changes such as persistent bloating, pelvic or tummy discomfort, reduced appetite or feeling full sooner than usual can help you recognise when you may need medical attention. Talking to a doctor about symptoms that don’t settle can help identify the underlying cause and ensure you get the right care early. Knowing your family history and personal risk can also help you discuss any concerns with your doctor.

Frequently Asked Questions (FAQs)

What is the survival rate for ovarian cancer?

Survival rates depend largely on the stage and type of ovarian cancer. Earlier-stage ovarian cancer generally has better survival outcomes than cancer diagnosed at a later stage¹⁸.

Is ovarian cancer treatable?

Ovarian cancer can be treated with surgery, chemotherapy and, for some people, targeted therapy. Early detection is generally linked with a better prognosis¹⁹.

Is ovarian cancer genetic?

Ovarian cancer can sometimes be genetic. Changes in genes such as BRCA1 and BRCA2 can increase the risk of developing ovarian cancer².

Can pelvic organ prolapse be a sign of ovarian cancer?

Pelvic organs prolapse is not usually a sign of ovarian cancer²⁰. It occurs when the womb, bladder or bowel bulges into the vagina because the supporting tissues have weakened. Symptoms of prolapse can include a feeling of heaviness or pressure in the lower abdomen or vagina, a bulge or lump in or around the vagina, constipation, or problems passing urine²¹.

Can HPV cause ovarian cancer?

HPV is mainly linked to cervical and some other cancers²² and is not usually known to cause ovarian cancer.

Can ovarian cancer spread to the lungs?

Yes. Advanced ovarian cancer can spread to the lungs and other parts of the body²³ .

Does PCOS increase the risk of ovarian cancer?

Some studies have suggested a possible link between polycystic ovary syndrome (PCOS) and ovarian cancer risk, particularly in younger (premenopausal) women. However, the evidence is limited and more research is needed to clarify whether PCOS is associated with an increased risk of ovarian cancer²⁴.

Eye Cancer: Symptoms, Causes, Types, Treatment & Prevention

Introduction

Your eyes can tell you a lot about your health, but what if something unusual starts to change them? Eye cancer is rare but serious, and it can affect both adults and children. Eye cancer can develop in various parts of the eye, and its symptoms can be easy to miss¹.

This article discusses types of eye cancer, its symptoms and causes, how the disease is diagnosed and treated, and when to consult a doctor.

What Is Eye Cancer?

Eye cancer is a rare cancer that develops in the eye or the tissues around it. It happens when abnormal cells grow in an uncontrolled way and form a tumour. Eye cancer can affect different parts of the eye. Initially, it may not show any specific signs, however, as it progresses it may lead to altered vision or other changes in or around the eyes^1,2.

Did You Know?

Some eye cancers may have no early symptoms. This means a person may not notice anything unusual at first, and the cancer may be found during a routine eye examination².
Eye cancer can affect people of all ages. Some types are more common in adults, while retinoblastoma, a cancer that starts in the light-sensitive part of the eye, mainly affects young children^1,3.
The most common type of cancer occurring within the eye is uveal melanoma. However, this also accounts for less than 5% of all melanomas, which means it is a relatively rare type of melanoma⁴.

Types of Eye Cancer

Eye cancer can develop in different parts of the eye, and there are several types depending on where it starts³.

A primary eye cancer is the cancer that starts in the eye or the tissues around it whereas a secondary eye cancer is the cancer that starts in another part of the body and spreads to the eye. This spread is called metastasis (when cancer cells travel from one part of the body to another).

Primary eye cancers include³:

Intraocular eye cancer that develops inside the eye.
Uveal melanoma is the most common eye cancer in adults. It starts in the uvea (the middle layer of the eye), which includes the iris (the coloured part of the eye), ciliary body (the part that helps the eye focus), and choroid (the layer that supplies blood to the eye).
Retinoblastoma is a rare eye cancer that mainly affects young children. It starts in the retina (the light-sensitive layer at the back of the eye) and can affect one or both eyes.
Eye lymphoma is a cancer that starts in lymphocyte cells of the immune system (the body’s defence system). It can develop in or around the eye.
Extraocular eye cancer which develops outside the eyeball, such as in the eyelids, tear glands or tissues surrounding the eye.
Basal cell carcinoma (BCC) and Squamous cell carcinomas are skin cancers that can start in the tissues covering or lining parts of the eye. They are less common than some other types of eye cancer.
Lacrimal gland cancer is a rare cancer arising from the tear-producing lacrimal gland.
Rhabdomyosarcoma is a soft-tissue cancer that can develop in the tissues around the eye, mainly affecting children³.

Causes of Eye Cancer

There is no single known eye cancer cause. Most eye cancers develop due to changes in the genes that control how cells grow and divide, but the exact reasons these changes occur are not always known. Several factors may increase the risk of developing certain types of eye cancer⁵.

Eye colour: Blue, green, or any light-coloured eyes have higher chances of developing eye melanomas⁶.
Age: Risk of most eye cancers increases as one ages. However, some cancers like retinoblastoma are more common in children⁷.
Specific eye conditions: Some unusual pigmentation around the eye area and certain moles can increase the chances of developing eye melanomas⁵.
Inherited conditions: Changes in certain genes can contribute to the development of eye cancer, which can be inherited from a parent or develop during a person’s lifetime. Rare inherited conditions, such as BAP1 tumour predisposition syndrome, can increase the risk of uveal melanoma and other cancers. Retinoblastoma can also occur when changes affect the RB1 gene; some of these changes are inherited, while others occur by chance⁸.
Sunlight or ultraviolet rays exposure: The possibility of getting eye melanomas and carcinomas may be higher with long-term exposure to ultraviolet rays⁸.
Infections like HIV and Immune suppression: A weakened immune system can increase the risk of some eye cancers, particularly eye lymphoma. People with HIV/AIDS and those taking medicines that suppress the immune system, such as after an organ transplant, have a higher risk of developing certain types of eye cancers like eye lymphoma⁸.

Eye Cancer Symptoms and Early Warning Signs

Eye cancer does not always cause symptoms, especially in its early stages. When symptoms do occur, they may include:

Decreased or blurred vision: Seeing worse than before⁹.
Flashes or floaters: Seeing flashes of light or dots or shapes in the vision⁹.
A black spot on the iris: A new mark on the coloured part of the eye or an existing one that increases in size⁹.
Changes in the pupil: The black opening in the middle of the eye may change in size or shape⁹.
Pain or discomfort in the eye: Pain occurring inside or near the eye¹⁰.
Swelling of the eyeball: The eyeball may look pushed out⁵.
A growth or lump: A new growth on the eyelid or on the eye¹.
Vision loss: Partial or not being able to see¹.
A white pupil in children: The pupil can appear white in photographs taken with flash. It could signify retinoblastoma⁷.

Treatment of Eye Cancer

The kind of treatment assigned to eye cancer mostly depends on its form, size, and position. Treating various forms of eye cancer can include:

Surgery: The cancerous formation may need to be surgically removed if it is still small. In some cases, the entire eye may need to be taken out to eliminate the tumour, which can be replaced by a prosthesis¹.
Radiotherapy: This method involves the use of radiation to destroy cancer cells. Whether internal radiotherapy is required or external depends upon the type of cancer¹¹.
Chemotherapy: Chemotherapy uses medicines to destroy cancer cells or slow their growth. It may be given directly into the eye, around the eye, or throughout the body, depending on the situation. Its use varies among different types of eye cancer and is commonly used in the treatment of retinoblastoma but less useful for melanomas⁷.
Cryotherapy: The technique implies very low temperatures to freeze affected cells (which is often used to treat significant form of retinoblastomathese include the opening of blood vessels, creating destruction of the surrounding tissues, and freezing cells at low temperatures¹².
Laser treatment: Laser treatment uses a focused, high-energy beam of light to destroy tumour tissue and the surrounding blood vessels feeding them. In retinoblastoma, laser treatment may be used in two ways: photocoagulation, which can destroy the blood vessels supplying the tumour, and thermotherapy, which uses heat from infrared laser light to destroy cancer cells. Laser treatment is generally used for small tumours, particularly those at the back of the eye¹².
Immunotherapy: Immunotherapy uses medicines that help the immune system recognise and attack cancer cells. It may be considered for certain types of melanomas or metastatic eye cancer, depending on the cancer type and individual circumstances¹.

Complications of Untreated Eye Cancer

Eye cancer has the potential to continue to grow and can cause major issues if not treated. Some complications may occur as a result, which include:

Loss of vision: A tumour can damage structures of the eye that are important for vision, potentially causing partial or complete loss of sight¹⁰.
Retinal detachment: Some eye tumours may cause the retina to separate from the back of the eye, which can lead to visual disturbances or vision loss¹³.
Changes in the appearance of the eye: As a tumour grows, it may cause swelling, bulging of the eye or other physical changes⁹.
Spread to nearby tissues: Advanced eye cancer may grow beyond the eye and affect surrounding tissues⁹.
Spread to other parts of the body: Some eye cancers can spread to distant organs through metastasis. The pattern of spread depends on the type of eye cancer; for example, uveal melanoma commonly spreads to the liver⁹.
Facial or eye changes after treatment: Treatment such as surgery may sometimes alter the appearance of the eye or surrounding face. Radiotherapy can also cause changes to the tissues around the eye and may affect vision or other eye functions⁹.
Serious complications in children: Untreated retinoblastoma can cause severe damage to the eye and blindness. It can also spread to the brain and other parts of the body, where it can become life-threatening⁹.

Early diagnosis and appropriate treatment can help prevent or reduce some of these complications¹⁰.

How to Prevent Eye Cancer?

It is difficult to prevent all types of eye cancers since some associated risk factors like genetics or inherited mutations are not modifiable. But there are measures that can be taken to protect your eyes and lower the risks¹⁰.

Protect your eyes from strong sunlight: Wear sunglasses that block UV (ultraviolet) rays and a wide-brimmed hat when outdoors.
Avoid sunbeds: Sunbeds expose the eyes and skin to UV radiation and may increase the risk of melanoma.
Watch out for signs: Look for unusual or lasting changes in your eyes, such as blurred or reduced vision, a dark/white spot on the coloured part of the eye, a lump in or around the eye, a change in how the eye looks, or ongoing eye irritation. If you notice any new or unusual changes, speak to your doctor.
Have regular eye tests: Some eye cancers may not cause symptoms at first and can be found during a routine eye examination.
Know your family history: Some rare eye cancers, such as retinoblastoma (a cancer that affects the retina, the light-sensitive layer at the back of the eye), can run in families. Children with a family history may need regular eye checks.

When to Consult a Doctor?

If you notice any new changes in your eyes or vision, speak to a doctor. You should also seek medical advice if¹⁰:

Changes in your vision are affecting your daily activities.
An eye problem is not improving.
You notice any unusual changes in a child’s vision.
You have risk factors for eye cancer, such as a family history of certain eye cancers or a condition that may increase your risk.

Early assessment can help identify the cause and, if needed, start eye cancer treatment sooner.

Conclusion

Eye cancer is a rare disease, but knowing its risk factors and symptoms can help you get medical advice early. Not all types of eye cancer can be prevented, but you can protect your eyes by limiting UV exposure, having regular eye check-ups and noticing any unusual changes in your vision. If you notice any changes that worry you, speak to a doctor. Early advice can help you get the right care when needed.

Frequently Asked Questions (FAQs)

Can eye cancer cause blurred vision or sudden vision loss?

Yes, blurred or reduced vision can be a symptom of eye cancer. However, sudden vision loss is not always caused by cancer and can have other serious causes. Sudden loss of vision needs urgent medical attention⁹.

Does eye cancer cause eye pain?

It can cause eye pain, but this is not a common feature with some types of eye cancer. Pain may occur in certain cases, particularly when the cancer affects surrounding tissues or causes pressure in the eye¹.

Can a dark spot on the eye be a sign of cancer?

A new dark spot on the iris (the coloured part of the eye) or a spot that becomes larger can be a sign of eye melanoma (a cancer that develops from pigment-producing cells). However, not every dark spot is cancerous⁶. You should consult an eye specialist when you notice any such changes.

Can eye cancer cause floaters and flashes of light?

Yes, eye cancer can sometimes cause floaters (small spots or shapes that move across your vision) and flashes of light. However, these symptoms are more commonly caused by other eye conditions, so they should not automatically be assumed to be cancer⁶.

Can eye cancer be detected during a routine eye examination?

Some eye cancers cause no early symptoms and may be found during a routine eye examination. An eye specialist can examine the inside of the eye and look for unusual changes or growths⁶.

Is Eye Cancer Curable?

Some types of eye cancer can be cured, particularly when they are found and treated early. The outlook depends on the type, size and location of the cancer and whether it has spread. For example, retinoblastoma can be curable when diagnosed before it spreads outside the eye⁷.

What is the first stage of eye cancer?

Different types of eye cancers have different stages. For uveal melanoma (most common type of eye cancer), Stage I means the tumour is small and remains in the choroid (the blood-rich layer at the back of the eye)⁶.

Can Vitamin B12 Deficiency Be a Sign of Cancer?

Introduction

Feeling unusually tired, weak, or experiencing numbness and tingling can sometimes be linked to vitamin B12 deficiency, a condition that occurs when the body does not get enough vitamin B12 or cannot absorb enough of it from the diet.

Vitamin B12 is a water-soluble vitamin that helps with red blood cell formation and maintenance of a healthy nervous system¹.

This blog will explain what is vitamin B12 deficiency, its causes and symptoms, how it is diagnosed, vitamin B12 deficiency treatment guidelines, and how long recovery may take, which could help in making informed decisions and better recovery.

What Is Vitamin B12 and Why Is It Important?

Vitamin B12, also known as cobalamin, is a vitamin that the body needs for several important functions. It is required for the development, myelination, insulation of the nerves, and normal neurological function of the central nervous system (which includes the brain and spinal cord). Vitamin B12 is also needed for the production of new red blood cells (erythropoiesis) and for DNA synthesis (an essential process involved in making and maintaining the body’s cells)^2,3.

Vitamin B12 also acts as a cofactor for enzymes involved in important metabolic reactions in the body. When vitamin B12 deficiency occurs, it can cause ineffective erythropoiesis, megaloblastic anaemia, and neurological changes such as numbness, tingling in the hands and feet, etc. (discussed in detail in the symptom section). Hence, vitamin B12 is vital for normal nerve function, red blood cell formation, and DNA synthesis².

What Causes Vitamin B12 Deficiency?

Vitamin B12 deficiency causes could be various, including not getting enough vitamin B12 from the diet, conditions affecting its absorption, certain medical conditions, and some medicines. Vitamin B12 deficiency causes include:

Pernicious anaemia: This is an autoimmune condition in which the immune system attacks stomach cells that produce intrinsic factor, a protein needed to absorb vitamin B12.
Dietary deficiency: People who do not regularly eat meat, fish, or dairy products may develop a deficiency; people following a vegan diet without vitamin B12 supplements or fortified foods are also at risk⁴.
Certain stomach conditions or surgery: Conditions such as autoimmune gastritis and atrophic gastritis can reduce the production of stomach acid or intrinsic factor, making it harder for the body to absorb vitamin B12⁵. Additionally, stomach surgery, such as gastrectomy, can also reduce vitamin B12 absorption⁴.
Intestinal conditions: Conditions affecting the intestines, such as Crohn’s disease, can interfere with the absorption of vitamin B12.
Certain medicines: Some medicines can reduce the amount of vitamin B12 in the body, including proton pump inhibitors (PPIs), nitrous oxide, and metformin.
Functional vitamin B12 deficiency: Some people can have problems related to vitamin B12 deficiency despite having apparently normal blood levels because of problems with proteins that transport vitamin B12 between cells⁴.

Signs and Symptoms of Vitamin B12 Deficiency

Vitamin B12 deficiency symptoms can include a wide range of problems that develop gradually but may worsen if the condition is left untreated. These may comprise of both, general body symptoms and problems affecting the brain and nervous system, such as:

Feeling weak or tired
Shortness of breath or rapid breathing
Headaches
Loss of appetite
Palpitations
Diarrhoea
Mouth ulcers and sore, red tongue
Problems with memory, understanding, or judgement
Numbness, pins and needles sensation, or weakness of muscle
Psychological problems, including depression, anxiety, and confusion
Problems with balance and coordination⁶
Optic nerve damage (may cause vision problems)⁷

How Is Vitamin B12 Deficiency Related to Cancer?

Vitamin B12 levels show complex links to cancer risk, and the relationship between vitamin B12 status and cancer is not fully understood yet. Rather than identifying it as a specific sign of cancer, Vitamin B12 deficiency in cancer patients is a multifactorial issue. Cancers involving parts of the digestive system, including the stomach and terminal ileum, may lead to B12 deficiency because these areas are involved in vitamin B12 absorption⁸. Conversely, pernicious anaemia, that can cause Vitamin B12 deficiency, is associated with an increased risk of stomach cancers⁹.

Vitamin B12 may also occur as a result of cancer treatments as they can damage the cells of digestive system causing impairment in absorption. Treatment side effects such nausea, vomiting and loss of appetite may also affect dietary intake and lead to Vitamin B12 deficinecy⁸.

Thus, vitamin B12 deficiency in people with cancer may happen because of poor diet, stomach or intestinal surgery, problems absorbing vitamin B12, side effects of treatment, or other stomach or intestinal conditions, rather than the cancer itself.

Other Conditions That Can Mimic Vitamin B12 Deficiency

Some medical conditions can cause symptoms like those seen with vitamin B12 deficiency, so doctors may consider them when evaluating a person with suspected vitamin B12 deficiency:

Lead toxicity: Lead poisoning is suspected to mimic vitamin B12 deficiency, as both can produce neurological symptoms; therefore, lead exposure may need to be considered when evaluating these symptoms^10,11.
Syphilis: Syphilis is another condition evaluated when vitamin B12 deficiency is suspected, as it also affects the nervous system causing symptoms similar to vitamin B12 deficiency^11,12.
HIV myelopathy: HIV related spinal cord disease known as HIV myelopathy affects the spinal cord can lead to symptoms related to nervous system similar to vitamin B12 deficiency^11,13.
Folate deficiency: Folate deficiency can also disrupt cell division and blood cell production leading to anaemia as seen in vitamin B12 deficiency; measuring both vitamin B12 and folate levels can help distinguish between them^11,14. However, folate deficiency generally does not produce the characteristic neurological manifestations of B12 deficiency.

How Is Vitamin B12 Deficiency Diagnosed?

Vitamin B12 deficiency is diagnosed using a combination of symptoms, medical history, physical examination, and blood tests rather than relying on symptoms alone. The following tests are commonly used¹¹.

Vitamin B12 blood test: Measures the levels of Vitamin B12 in the blood for any deficiency. Serum B12 is the usual initial test, but a normal serum B12 does not always exclude deficiency, particularly when clinical suspicion is high.
Complete blood count (CBC): Checks for anaemia and unusually large red blood cells by evaluating the complete blood count. However, note that neurological B12 deficiency can occur with normal haemoglobin and MCV.
Folate test: Helps distinguish vitamin B12 deficiency from folate deficiency, which can cause similar symptoms.
Methylmalonic acid (MMA) and homocysteine: May be checked when the B12 result is borderline or the diagnosis is unclear.
Anti-intrinsic factor antibodies: Can help identify pernicious anaemia when the cause of B12 deficiency is uncertain. Anti-intrinsic factor antibodies are useful when autoimmune gastritis/pernicious anaemia is suspected, but a negative result does not exclude autoimmune gastritis/pernicious anaemia.

Note: Any test results should be interpreted along with symptoms and other clinical findings. A normal vitamin B12 level or a negative antibody test does not always rule out vitamin B12 deficiency or pernicious anaemia. Consult a doctor if your symptoms persist even when your test results are normal.

Treatment and Ways to Raise Vitamin B12 Levels

Vitamin B12 deficiency treatment guidelines involve the following treatments based on the individual condition^15,16:

1. Vitamin B12 Injections

People with significant blood related or neurological effects from vitamin B12 deficiency and very low levels may need vitamin B12 replacement by intramuscular injection. Talk to your doctor about the right dose and duration of treatment before starting any treatment.

2. Oral Vitamin B12 Supplements

For some people with vitamin B12 deficiency, oral vitamin B12 supplements may be needed. Generally, your doctor will prescribe at least 1 mg per day for a specific duration when supplements are given in certain situations involving malabsorption. You may need to get blood count checks after 1 to 2 months, with follow-up blood tests. However, you should always consult with your doctor for the exact dosage before starting any medication for the ideal treatment.

3. Vitamin B12 Rich Foods

Vitamin B12 is found naturally in animal-based foods such as milk, cheese, yoghurt, and eggs. The dietary B12 deficiency occurs in people following a strict vegan diet.

4. Treating Underlying Cause

The cause of the deficiency should be investigated, including possible malabsorption, dietary deficiency, medicines, or pernicious anaemia, so that treatment can be appropriately selected.

5. Follow Up Blood Tests

People receiving oral vitamin B12 replacement should have their response checked with vitamin B12 testing after about 2 to 3 months, followed by further monitoring as advised.

6. Long Term Treatment When Necessary

People with conditions that cause ongoing B12 absorption problems, such as pernicious anaemia, may need long term or lifelong vitamin B12 injections.

Important: The type, dose, and duration of vitamin B12 treatment depend on the cause and severity of the deficiency and whether the body can absorb vitamin B12 properly. Only your doctor can recommend the most suitable treatment for you.

How Long Does It Take to Recover from Vitamin B12 Deficiency?

Recovery from vitamin B12 deficiency varies depending on its cause, severity and individual’s response to treatment. Failure to respond should first prompt assessment of adherence, adequacy of dose, diagnosis, ongoing malabsorption, continued exposure to a causative factor, and alternative diagnoses.

Follow-up blood tests may be done to check whether vitamin B12 levels and blood counts are improving. If symptoms or test results do not improve, the doctor may review the treatment, dose, vitamin B12 absorption, or other possible causes¹⁷.

People with severe deficiency or neurological symptoms may need vitamin B12 injections initially, followed by regular maintenance treatment. In some cases, long-term or lifelong treatment may be needed if the underlying cause continues¹⁷.

Note: The type and duration of treatment and the need for follow-up tests depend on the cause and severity of the deficiency as well as treatment response.

When Should You See a Doctor?

You should see a doctor if you think you may have vitamin B12 deficiency, especially if you have symptoms such as extreme tiredness, lack of energy, pins and needles, a sore or red tongue, muscle weakness, vision problems, or changes in memory, understanding, or judgement. Prompt treatment is particularly important when vitamin B12 deficiency is accompanied by significant blood abnormalities or neurological symptoms.

People at higher risk, including strict vegans, people with pernicious anaemia, those taking certain long term medications that include proton pump inhibitors, biguanides, contraceptive pills, people with gastric conditions like coeliac disease or inflammatory bowel disease, and those who have had gastric surgery, should be cautious and evaluate regularly for this condition¹⁵.

It is important to seek medical evaluation because vitamin B12 deficiency can often be diagnosed with symptoms and a blood test, and treatment should begin as soon as possible for a better outcome. Although many symptoms improve with treatment, some problems caused by vitamin B12 deficiency, particularly nervous system problems, can sometimes be irreversible¹⁸.

Conclusion

Recognising vitamin B12 deficiency early is important because prompt diagnosis and treatment can help prevent complications such as anaemia, nerve damage, and neuropsychiatric problems. Identifying the underlying cause is also important because different causes, such as dietary deficiency or problems with B12 absorption, may require different treatment approaches. Following the recommended treatment and continuing it when necessary, can help restore B12 levels and control symptoms. Seeking medical evaluation when symptoms are noticed can therefore help ensure timely diagnosis and appropriate management.

Frequently Asked Questions (FAQs)

What foods are rich in vitamin B12?

Vitamin B12 is naturally found in fish, meat, poultry, eggs, milk, and other dairy products. Plant foods do not naturally contain vitamin B12 unless they are fortified; fortified breakfast cereals and some nutritional yeast products provide B12¹.

Can vitamin B12 deficiency cause nerve problems?

Yes. Vitamin B12 deficiency can cause nerve related problems, including numbness or tingling in the arms and legs, weakness, and loss of balance¹.

Can you fully recover from B12 deficiency?

People who are treated promptly for vitamin B12 deficiency generally have a better treatment outcome, and neurological symptoms may partially improve after treatment. However, recovery can take months or even years, and the best response is seen in people without severe neurological problems¹¹.

Which cancers are associated with vitamin B12 deficiency?

Vitamin B12 deficiency has been reported in association with certain cancers, particularly gastrointestinal cancers, that include cancers of the stomach, pancreas, and terminal ileum, where disease or treatment may interfere with vitamin B12 absorption⁸.

Can vitamin B12 deficiency occur during cancer treatment?

Yes. Vitamin B12 deficiency can occur in people undergoing cancer treatment, with the risk influenced by the type of cancer and its treatment, particularly when the digestive system or vitamin B12 absorption is affected⁸.

Is vitamin B12 deficiency common in older adults?

Yes, vitamin B12 deficiency is more common in older adults. Factors like higher incidence of atrophic gastric in elderly that impacts vitamin B12 absorption and poor nutrition may contribute. Treatment outcomes are also generally better in younger patients than in older individuals^11,16.

Is vitamin D deficiency linked to B12 deficiency?

Vitamin D and vitamin B12 levels may be related as some underlying conditions can lead to deficiencies of both. These include poor nutrition, malabsorption syndromes, atrophic gastritis or certain autoimmune diseases¹⁷. However, further evidence is needed to prove any direct link.

Can Sunscreen Cause Cancer? What the Research Says

Introduction

Sunscreen is widely used as an essential part of skin care to provide protection from the harmful effects of sun exposure. However, concerns about the safety of sunscreen and its ingredients have raised questions about whether regular, long-term use could have harmful effects like cancer risk. But how much truth is there to these concerns?

To address these questions, it is important to understand what research says about sunscreen safety, its ingredients, and its potential health effects. This blog will help you understand aspects such as sunscreen for skin cancer prevention, along with the benefits and correct use of sunscreen, to help you make informed choices about protecting your skin from the sun.

Can Sunscreen Cause Cancer?

If you have wondered, ‘Does sunscreen cause skin cancer?’, understanding the available scientific evidence can help ease your mind.

Current scientific evidence does not show that using sunscreen causes cancer¹. In fact, sunscreen helps protect the skin from ultraviolet (UV) radiation which is a known risk factor for skin cancer².

Concerns about sunscreen often arise from questions about specific ingredients and their absorption into the body³. However, finding that an ingredient is absorbed does not mean that it causes cancer. The available evidence has not established sunscreen use as a cause of cancer^1,3.

Is Sunscreen Safe to Use?

Overall, sunscreen is considered safe to use when applied as directed. Sunscreens are formulated in a way that helps ensure that they meet standards for safety and effectiveness⁴. However, safe does not mean that every ingredient has been studied equally extensively.

The Food and Drug Administration (FDA) of the United States continues to request additional safety data for some sunscreen ingredients. But the FDA has also clarified that requesting more data does not mean these ingredients have been shown to be unsafe^5,6. So, based on current evidence, there is no reason to stop using sunscreen because of fears that it causes cancer.

Any side effects (if they occur) from sunscreen are generally mild⁷. These may include⁸:

Skin irritation: redness, itching, or burning.
Allergic contact dermatitis: an allergic reaction (rare) to certain sunscreen ingredients

Note: These reactions do not outweigh the benefits of regular sunscreen use for protecting the skin from UV damage. If you experience a reaction to a sunscreen, consult your doctor about choosing a suitable alternative rather than stopping sunscreen use altogether.

Can Sunscreen Prevent Skin Cancer?

Concerns about sunscreen and cancer have led many people to question whether regular sunscreen use is safe. But the reality is different.

UV radiation can damage skin cells and increase the risk of skin cancer. Sunscreen use can help reduce the risk of skin cancer by protecting the skin from this harmful radiation⁷. Therefore, regular sunscreen use is an important part of a broader sun-protection strategy.

Let us understand the basics of sunscreen for skin cancer prevention⁷:

Blocks harmful UV radiation: A broad-spectrum sunscreen protects against both UVA and UVB rays. Both of these rays can damage the skin and may contribute to skin cancer.
Reduces UV-related DNA damage: By limiting the amount of UV radiation reaching the skin, sunscreen helps reduce damage at the cellular level.
Helps avoid sunburn: Sunburn is a sign of UV-related skin injury. So, by protecting against repeated sunburns, sunscreens can help reduce cumulative skin damage⁷.
May reduce the risk of skin cancer with regular use: Evidence supports sunscreen as part of skin cancer prevention, with particularly strong evidence for reducing squamous cell carcinoma (cancer in cells that form the middle and outer layers of the skin)⁹.

Sunscreen Ingredients and Cancer Risk

Sunscreens contain certain active UV filters that protect the skin from harmful UV radiation¹⁰. Commonly recommended sunscreen ingredients include:

Zinc oxide and titanium dioxide: These are inorganic UV filters (mineral-based compounds that absorb and scatter UV radiation). They are considered safe and effective for use in sunscreens at specified concentrations⁵. There is no evidence that their topical use in sunscreen causes cancer.
Avobenzone, cinoxate, dioxybenzone, ensulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, oxybenzone, padimate O, sulisobenzone, and bemotrizinol: These are organic UV filters (chemical/carbon-based compounds that absorb UV radiation). They are permitted for use by regulatory authorities in most countries. Some ingredients continue to be reviewed for safety, but this does not mean they have been shown to cause cancer or other serious health problems^5,10.

Ingredients like aminobenzoic acid (PABA) and trolamine salicylate are generally not recommended. This is because:

PABA has been associated with allergic skin reactions in some individuals^5,11. Laboratory studies have also raised concerns about its potential to increase the effects of UV radiation on cells. However, these findings have not been established in human skin¹².
Trolamine salicylate, on the other hand, has safety concerns related to salicylate toxicity⁵.

It is important to understand that these are specific safety considerations for these ingredients and do not mean that sunscreens are harmful or unsafe when used as directed.

Important: The classification and number of approved UV filters can vary by regulatory authority and may change as new ingredients are evaluated. Therefore, always check the latest information from the relevant regulatory authority for the most up-to-date list of approved UV filters.

How to Choose a Safe Sunscreen?

When choosing a sunscreen for cancer prevention, look for the following features:

Broad-spectrum protection: Choose a sunscreen that protects against both UVA and UVB rays. This provides more complete protection from UV-related skin damage.
SPF 30 or higher: An SPF of 30 or higher is recommended for adequate protection against UVB radiation when the sunscreen is applied correctly.
Water resistance: Water-resistant sunscreen is useful during swimming, sweating, or other activities involving water. Remember that no sunscreen is completely waterproof, so it needs to be reapplied as directed¹³.
Suitable for your skin: If you have sensitive or easily irritated skin, consider products formulated for sensitive skin and avoid ingredients that you know may cause irritation or allergic reactions.
Check the label: Choose a sunscreen that is properly labelled and approved or authorised by the relevant regulatory authority in your country.

How to Use Sunscreen Correctly?

Follow these simple steps to get the most protection from your sunscreen⁶:

Apply before sun exposure: Apply sunscreen about 15 minutes before going outdoors so it has enough time to form a protective layer on the skin.
Cover all exposed skin: Apply sunscreen evenly to all exposed areas, including the face, neck, arms, and legs. Remember to avoid contact with the eyes and mouth.
Use enough sunscreen: Apply a generous, even layer to all exposed areas. An average-sized adult needs about 1 ounce (roughly a shot-glassful) to cover the entire body.
Reapply regularly: Reapply at least every 2 hours and more often after swimming, sweating, or towel-drying.
Do not forget commonly missed areas: Make sure to apply sunscreen to ears, nose, hands, lips (use an SPF lip balm), back of the neck, tops of the feet, along the hairline, exposed scalp, especially if you have thinning or no hair.

Note: Sunscreen should be used as one part of overall sun protection, along with seeking shade, wearing protective clothing, and avoiding excessive UV exposure⁷.

When to Consult a Doctor?

You should consider consulting a doctor if you have concerns about your skin or notice any unusual changes, such as^14,15:

A new or changing mole or skin growth
A sore or wound that does not heal
A spot that bleeds or crusts
A skin lesion that changes in size, shape, or colour
A reaction to sunscreen, such as severe irritation, swelling, rash, or difficulty breathing

If you notice a suspicious or persistent skin change, do not assume it is related to sunscreen. Consult a doctor, as they can examine it and determine whether further evaluation is needed.

Conclusion

Understanding the link between sunscreen and cancer can help address common concerns about sunscreen safety.

Sunscreen is an important part of protecting your skin from harmful UV radiation. Current evidence does not show that using sunscreen as directed causes cancer, while excessive UV exposure is a well-established risk factor for skin cancer. Therefore, choosing a broad-spectrum sunscreen with SPF 30 or higher, applying enough, and reapplying it regularly can help provide effective protection.

Frequently Asked Questions (FAQs)

Is it safe to wear sunscreen every day?

Daily sunscreen use is generally considered safe and is recommended to help protect the skin from harmful UV radiation⁴. There is no good evidence that regular sunscreen use causes cancer when you use it as mentioned on its label.

Does mineral sunscreen cause cancer?

Mineral sunscreens typically contain zinc oxide or titanium dioxide^5,7. Current evidence does not show that using these ingredients topically in sunscreen causes cancer.

Is sunscreen carcinogenic?

There is no evidence that sunscreen itself is carcinogenic when used as directed. Some ingredients continue to be evaluated for safety, but this does not mean they have been shown to cause cancer⁵.

Can expired sunscreen cause cancer?

There is no evidence that expired sunscreen causes cancer. However, its effectiveness may decrease over time, meaning it may not provide the protection indicated on the label. So, in such cases, it is best to replace sunscreen after its expiration date^4,6.

Do sunscreen chemicals get absorbed into the body?

Studies have shown that some chemical sunscreen ingredients can be absorbed through the skin and detected in the bloodstream^10,16. However, absorption does not mean that an ingredient is harmful or causes cancer. The FDA has requested additional safety data for some ingredients to better understand their effects⁵.

Common Cancer Symptoms and Warning Signs in Women

Introduction

Sometimes you may notice an unusual change in your body, such as constant fatigue, unexplained bleeding, or a new lump¹. While these symptoms can have many causes, some of these may be warning signs of cancer and should not be ignored if they persist. This article will discuss the most common cancer symptoms in women, the warning signs to watch for, and when it is important to seek medical advice.

What Are Cancer Symptoms in Women?

To understand what are the symptoms of cancer in women, we first need to understand what cancer is and how it can affect the body.

Cancer is a broad term for a group of diseases in which abnormal cells grow uncontrollably and may affect nearby tissues or spread to other parts of the body². Because cancer can develop in almost any part of the body, the symptoms can vary depending on the type and location of the cancer³.

Since men and women have some anatomical differences, certain cancers and their symptoms can be specific to women, particularly those involving the reproductive organs⁴. However, many symptoms are still common across both sexes and could occur with different types of cancer¹.

Did You Know?

Cervical cancer remains a major cancer affecting women worldwide. The most common cancers vary by country, and cervical cancer is the leading cancer among women in 26 countries².
Infection with human papillomavirus (HPV) is very common. In fact, most people who have had sexual contact are exposed to HPV at some point. But it is very important to know that only certain high-risk types of the infection may lead to cancer⁵.
Many cancers can be prevented. World Health Organization (WHO) and its International Agency for Research on Cancer (IARC) estimate that around 37% of new cancer cases worldwide in 2022 were linked to causes that could have been avoided⁶. This highlights the importance of different cancer prevention strategies.

Common Cancer Symptoms in Women

Although many cancer symptoms are similar in men and women, some symptoms may be different due to differences in anatomy or location of the cancer (e.g., cancers of the reproductive system). These include⁷:

Bloating or feeling full quickly
Abdominal or back pain
Abnormal vaginal bleeding or discharge
Pelvic pain or pressure
Changes in urination or bowel habits
Vulvar changes (persistent itching, ulcers, or other unusual skin changes)

Note: These symptoms do not always indicate cancer; however, if a symptom is new, persistent, or unusual for you, talk to your doctor.

Early Cancer Symptoms in Women

Early symptoms of cancer in women may be subtle and similar to symptoms of many common health conditions. Some early symptoms of cancer in women may include^1,8:

Persistent Fatigue: Unusual or extreme tiredness that does not improve with adequate rest.
Loss of Appetite: Persistent loss of appetite or difficulty swallowing.
Unexplained Weight Changes: Losing or gaining a significant amount of weight.
Persistent Cough or Hoarseness: Cough or hoarseness that does not resolve, particularly when accompanied by coughing up blood or bloody mucus.
Persistent or Unexplained Pain: Pain that is new, does not go away, or gradually becomes worse without an obvious cause.
Unusual Bleeding or Bruising: Bleeding without a known cause, such as blood in the stool or urine, or unusual bruising.
Persistent Changes in Bowel Habits: Ongoing constipation, diarrhoea, changes in stool appearance, or other persistent bowel changes.
Changes in Bladder Habits: Pain during urination, blood in the urine, or a noticeable change in how frequently you need to urinate.
Fever or Night Sweats: Recurrent fever or persistent unexplained night sweats.
Persistent Headaches or Changes in Vision or Hearing: New or persistent neurological symptoms, including headaches or unexplained changes in vision or hearing.
Changes in the Skin: A new or changing mole, a sore that does not heal, or other unusual changes in the skin.
Unexplained Lumps or Swelling: A new lump, thickening, or swelling in the breast (symptoms of breast cancer in women), lymph nodes, or another part of the body.

Types of Cancer Symptoms in Women

Below are the major cancers affecting women and symptoms commonly associated with them.

1. Cervical Cancer

Cervical cancer begins in the cervix, the lower, narrow end of the uterus⁴. Common cervical cancer symptoms may include^7,9:

Abnormal vaginal bleeding
Heavier or longer menstrual periods than usual
Vaginal bleeding after menopause
Unusual vaginal discharge
Pelvic pain or pain during sexual intercourse
Pain or difficulty when urinating

2. Ovarian Cancer

Ovarian cancer begins in the ovaries, which are located on either side of the uterus. Some ovarian cancers can also begin in the fallopian tubes⁴. Common symptoms may include¹⁰:

Persistent bloating or swelling of the abdomen
Feeling full quickly (early satiety) or difficulty eating
Abdominal/pelvic/back pain
Frequent or urgent need to urinate
Constipation or other changes in bowel habits
Unexplained tiredness
Changes in menstrual patterns in some women

3. Uterine/Endometrial Cancer

Uterine cancer begins in the uterus, the pear-shaped organ in the pelvis where a baby develops during pregnancy⁴. Common symptoms may include¹¹:

Vaginal bleeding after menopause
Bleeding between periods
Heavier or longer periods than usual
Pain during sex
Pelvic pain or pressure or lumps in some cases

4. Vaginal Cancer

Vaginal cancer begins in the vagina, the hollow, tube-like passage connecting the lower part of the uterus to the outside of the body⁴. Common symptoms may include¹²:

Abnormal vaginal bleeding, particularly after sex or after menopause
Unusual vaginal discharge
A lump or mass in the vagina
Pelvic pain or pressure
Pain during sex
Difficulty or pain while urinating

5. Vulvar Cancer

Vulvar cancer begins in the vulva, the external part of the female genital organs⁴. Common symptoms may include¹³:

Persistent itching, burning, or tenderness of the vulva
Changes in the colour or texture of the vulvar skin
A lump, sore, ulcer, or wart-like growth
A rash or area of thickened skin
Bleeding from the vulva that is not related to periods
Persistent pain in the vulvar area

6. Breast Cancer

Symptoms of breast cancer include¹⁴:

A new breast or underarm lump
Changes in breast shape or size
Nipple changes such as unusual nipple discharge (e.g., bloody discharge) or nipple turning inward
Redness or swelling in the breast or nipple area
Puckering or dimpling of the breast skin
Pain in the breast

Other cancers and their respective symptoms that are commonly seen in women include:

Lung cancer symptoms: Persistent cough, shortness of breath, chest pain, hoarseness, or coughing up blood¹⁵.
Symptoms of colon cancer: Persistent changes in bowel habits, blood in the stool, abdominal discomfort, unexplained weight loss, or fatigue¹⁶.
Symptoms of skin cancer in women: A new or changing mole, unusual skin growth, or a sore that does not heal¹⁷.
Symptoms of thyroid cancer in women: A lump or swelling in the neck, difficulty swallowing, or persistent hoarseness¹⁸.
Symptoms of blood cancer in women: Persistent fatigue, frequent infections, unexplained fever, easy bruising or bleeding, swollen lymph nodes, and unexplained weight loss¹⁹.

Cancer Symptoms in Younger vs Older Women

Cancer could occur in women of any age. However, the risk of developing many cancers generally increases with age²⁰.

Although the symptoms themselves may not be different in younger and older women, the way symptoms are noticed may vary (see the table below).

Aspect	Younger Women	Older Women
Cancer risk	Cancer is less common overall, but it can still occur at a younger age²¹.	The risk of many cancers generally increases with age²⁰.
Bleeding pattern	Abnormal, heavy, prolonged, or irregular menstrual bleeding²².	Any vaginal bleeding occurring 12 months after menopause²³.
How symptoms may be perceived	Symptoms may sometimes be mistaken for menstrual, hormonal, or reproductive problems.	Symptoms may sometimes be attributed to ageing or other existing health conditions.
Screening and awareness	Follow age-appropriate screening recommendations and be aware of personal and family risk factors²⁴.	Staying up-to-date with recommended cancer screenings becomes increasingly important with age²⁴.

Important: Age should never be used as a reason to ignore a concerning symptom. Whether you are young or old, persistent, unusual, or unexplained changes in the body should be discussed with a doctor.

What Are the Causes and Risk Factors of Cancer in Women?

Cancer does not have a single cause. It develops when changes in cells cause them to grow and divide abnormally. These changes can result from a combination of genetic factors, environmental exposures, lifestyle factors, and certain infections. Common factors that can increase the risk of cancer include^1,2:

Tobacco use
Alcohol consumption
Unhealthy diet
Overweight or obesity
Physical inactivity
Radiation exposure
Certain infections (like HPV)
Family history and inherited genes
Exposure to harmful chemicals
Increasing age

Important: Having a risk factor does not mean that a person will develop cancer. Similarly, cancer may sometimes also occur in people without any obvious risk factors.

How Is Cancer Diagnosed in Women?

If cancer is suspected because of symptoms, a routine check-up, or a screening test, the doctor may recommend several tests to find out what is causing the changes¹. The tests recommended depend on the type of cancer, symptoms, and a person’s overall health. Common diagnostic tests may involve:

Blood tests: Blood tests like tumour marker tests may help identify abnormalities associated with certain cancers²⁵.
Imaging tests: Tests such as mammography, X-ray, ultrasound, CT scan, and MRI scan can help doctors look for abnormal areas or tumours¹.
Endoscopy: A thin, flexible instrument with a camera may be used to examine certain areas of the body²⁵.
Biopsy: If an abnormal area is found, a small sample of tissue may be removed and examined under a microscope. A biopsy is always needed to confirm whether cancer is present²⁵.

Note: Once cancer is confirmed, further laboratory or imaging tests may be performed to determine how far it has spread and help doctors plan an appropriate management plan.

How to Reduce Cancer Risk

Many cancer risks can be reduced through healthy lifestyle choices, vaccination, and limiting exposure to known cancer-causing factors. Some important steps include:

Avoid tobacco: Do not smoke or use tobacco products. Additionally, try to avoid exposure to secondhand smoke²⁶.
Maintain a healthy weight: Keeping your weight within a healthy range can help lower the risk of cancer².
Eat a balanced diet: Include plenty of fruits, vegetables, and other nutritious foods as part of a healthy eating pattern².
Stay physically active: Regular physical activity can help reduce cancer risk and support overall health^1,26.
Limit alcohol: Reducing alcohol intake or avoiding alcohol completely could lower the risk of several types of cancer²⁶.
Get recommended vaccinations: Certain vaccines (such as the HPV and hepatitis B vaccines) may help reduce the risk of these infections associated with certain cancers¹.
Protect your skin from UV radiation: Limit excessive sun exposure, avoid artificial tanning devices, and use appropriate sun-protection measures².
Reduce exposure to harmful substances: Follow safety measures when working with chemicals, radiation, or other known carcinogens².
Limit exposure to environmental pollutants: Reducing exposure to harmful chemicals, air pollutants (e.g., tobacco smoke and asbestos), and water pollutants (e.g., arsenic), respectively, may help lower cancer risk²⁶.
Follow recommended cancer screening: Regular screening can help detect breast, cervical, colorectal, and lung cancers early, or identify precancerous changes. This allows timely treatment and potentially improves outcomes²⁴. For more information, discuss your personal and family risk factors with your doctor to determine which cancer screening tests are appropriate for you and when you should have them.

Remember: The above-mentioned prevention steps cannot eliminate cancer risk completely, but may significantly reduce the risk of developing certain cancers and support overall health.

When Should You Consult a Doctor?

If you notice any new, unusual, or persistent changes in your body, it is important to get them checked. These include¹:

A symptom that persists or keeps getting worse
Unexplained bleeding, pain, weight loss, or fatigue
A new lump, swelling, or skin change
Any other change that feels unusual or concerning to you

Conclusion

Cancer symptoms in women may vary widely depending on the type of cancer. Although many of these symptoms may be caused by conditions that are not cancer, paying attention to new, unusual, persistent, or unexplained changes in your body can help ensure that potential problems are identified early.

To support early diagnosis and timely treatment, you should know the warning signs, follow recommended screening and prevention measures, and speak with a doctor when something does not feel right.

Frequently Asked Questions (FAQs)

Can unexplained weight loss be a sign of cancer in women?

Unexplained or significant weight loss may sometimes be associated with cancer⁸. However, weight loss has many possible causes, so it is best to discuss this with a doctor.

When can unusual vaginal bleeding be a sign of cancer?

Unusual vaginal bleeding may be a warning sign of cervical, uterine, vaginal, or other gynaecologic cancers. This includes bleeding between periods, unusually heavy or prolonged periods, bleeding after sex, or any vaginal bleeding after menopause^9,13. Therefore, any unusual bleeding should be evaluated by a doctor.

Can persistent bloating be a symptom of cancer?

Frequent bloating, particularly when accompanied by feeling full quickly, abdominal or pelvic pain, or changes in bowel or bladder habits, may be associated with ovarian cancer^8,10. Since bloating is common and has many causes, persistent symptoms should be checked.

When should a breast lump or breast change be checked for cancer?

Any new lump, thickening, change in breast size or shape, nipple change, unusual discharge, or skin change should be assessed by a doctor, especially if the change is new or persists¹⁴.

Can skin changes or a changing mole be an early sign of cancer?

A new or changing mole, unusual skin growth, or a sore that does not heal can be a warning sign of skin cancer. Therefore, changes in a mole’s size, shape, colour, or appearance, or a lesion that bleeds or repeatedly develops a crust, should be checked by a doctor¹⁷.

Which cancer symptoms in women should not be ignored?

Any symptoms that are new, persistent, unexplained, or worsening should be evaluated by a doctor. These may include unusual bleeding, a new lump, unexplained weight loss, persistent fatigue or pain, ongoing bloating, changes in bowel or bladder habits, persistent cough, or unusual skin changes^1,8. Also, remember that having these symptoms does not mean you have cancer, but getting concerning changes evaluated can help detect problems early.

Can Tattoos Increase Your Risk of Cancer?

Introduction

Getting a tattoo can feel exciting, but you may wonder whether the ink could affect your health years later. Tattoos are common worldwide yet concerns about their safety and possible long-term effects continue to grow. Some people also question whether tattoo inks contain ingredients that could increase cancer risk. Understanding what research says can help you make informed choices¹. In this article, we will discuss tattoos and their risk of cancer, if any.

Can Tattoos Cause Cancer?

At present, tattoos are not proven to directly cause cancer. Some studies have raised concerns about a possible connection between tattoos and certain cancers, but the available evidence isn’t strong enough to confirm that tattooing itself is the cause. However, researchers are studying whether some substances in tattoo inks could have long-term effects on the body^1,2.

Are Tattoos Safe?

Although there isn’t a direct connection between tattoos and cancer, there are some other potential risks associated with tattoos. A safer tattoo experience depends on several factors, including the cleanliness of the studio, the tattoo artist’s hygiene practices, the condition of the equipment used, and proper aftercare^1,3. Using clean, single-use needles can help reduce the risk of infections³.

Since tattooing involves breaking the skin, maintaining good hygiene during the procedure and following proper aftercare can help prevent infections while the tattoo heals. It is also important to remember that tattoo inks are not all the same. Their ingredients can vary, and some pigments may cause skin reactions in certain people. Therefore, choosing a reputable tattoo provider is an important part of reducing avoidable complications¹.

How Might Tattoo Ink Affect the Body?

During tattooing, needles push ink into the deeper layer of the skin called the dermis. Because the pigment is placed below the skin’s surface, it can remain there for many years. The body recognises tattoo pigment as a foreign substance and responds to it. Some pigment particles may remain within skin cells, while others can move through the body.

The following are some concerns related to tattoo ink:

The ink can remain in the skin for a long time and cause chronic inflammation and changes such as fibrosis (formation of extra scar-like tissue in the skin), and granuloma formation (small nodules caused by a build-up of immune cells)¹. It may affect the function of certain immune cells in the body⁴.
Some particles from the ink may travel from the tattooed area to nearby lymph nodes or organs through the lymphatic system or blood¹. According to some studies, ink reaching the lymph nodes could have been linked to the occurrence of blood cancers like lymphoma⁵.
Ultraviolet (UV) rays from sunlight or laser treatment can break down tattoo ink and may create new substances that could be harmful to the body.

However, the long-term effects of some ink ingredients are still being studied, so their overall impact on health is not fully understood¹.

Is There a Link Between Tattoo Ink and Cancer?

Researchers have found that certain tattoo inks can contain substances that may be harmful, including chemicals with potentially carcinogenic properties⁶. However, the presence of these substances does not mean that getting a tattoo will cause cancer.

The following are some research findings:

Certain inks can contain substances such as heavy metals, polycyclic aromatic hydrocarbons (PAHs), phthalates and other chemicals. Some of these substances are known or suspected to increase cancer risk^1,6.
In some animal studies, certain cobalt- and zinc-based tattoo pigments caused inflammation and affected how immune cells fight infections and identify abnormal cells¹.
According to some recent studies, tattoos were linked to a higher risk of lymphoma, a type of blood cancer. Ink accumulation in the lymph nodes may be one possible cause for this link, but more research is needed to confirm it⁵.
Some skin cancers such as melanoma, squamous cell carcinoma and keratoacanthoma and have also been reported in people with tattoos. However, simply having a tattoo does not mean it caused the cancer.
Long-term effects of tattoo ink are still being studied because different inks can contain different ingredients⁷.

Other Health Risks Associated with Tattoos

People often wonder, “Can tattoos cause skin cancer?” Because tattooing involves repeatedly puncturing the skin, it can lead to several complications, particularly when proper hygiene or aftercare is lacking.

Common problems include:

Infections: Microorganisms can enter damaged skin and can cause staphylococcal and streptococcal bacterial infections, viral infections like human immunodeficiency virus (HIV), hepatitis, etc.
Allergic Reactions: Some people may develop an itchy rash or other reaction to a particular pigment, sometimes even long after getting the tattoo⁸.
Skin Irritation¹: Mild redness, tenderness and swelling can occur while the skin heals.
Scarring and Keloids: Tattooing can sometimes leave scars as the skin heals. People who are prone to keloids may develop thick, raised scars that extend beyond the original tattooed area.
Granulomas: Some people may develop small bumps at the tattooed area when the immune system reacts to tattoo ink because it recognises the ink as a foreign substance⁸.

Who May Be at Higher Risk of Tattoo Complications?

Although many people get tattoos without serious problems, certain factors can increase the risk of getting complications. The following people might be at a higher risk of tattoo complications:

People with a weak immune system (might be at a higher risk of developing infections from tattooing)⁹
People with a history of allergic reactions or with sensitive skin¹
People prone to keloids or raised scars⁸
People who get tattoo done in an unhygienic environment or under non-sterile conditions⁶
People who are frequently exposed to sunlight after tattooing (can cause photoallergic reactions such as hives)¹
People getting a tattoo over irritated, damaged or infected skin
People who do not follow proper measures after getting a tattoo¹
People taking certain medicines such as anticoagulants (can cause severe bruising)¹⁰

Note: If a health condition or medicine affects your healing or immune system, talk to your doctor before getting a tattoo.

How to Reduce Risks Before Getting a Tattoo?

There are several practical steps to make tattooing safer:

Select a professional tattoo studio with good hygiene standards.
Make sure the artist uses sterile, single-use needles and clean equipment³.
Ask what type of ink will be used and whether it comes from a reliable manufacturer.
Do not get a tattoo on skin that has an active rash, a wound, infection or other irritation¹¹.
In case of previously developed keloids or reactions to tattoo products⁸, discuss this before the procedure.
Ask your doctor about getting a tattoo, especially if you are on any medications or have any skin conditions^10,12.
Ask the artist how to clean and protect the new tattoo so that the skin can heal properly.

Note: Tattooing can carry different risks depending on your health, skin condition, and medications. These tips are for general information and should not replace advice from a qualified doctor. If you have any health concerns, speak with your doctor before getting a tattoo.

Can Tattoos Affect Skin Cancer Detection?

Tattoo ink can sometimes make it harder to notice changes in the skin. This is especially important when a tattoo covers a mole, birthmark or another existing skin mark.

Tattoo ink may make changes in the colour or border of a cancerous mole harder to see¹³.
A tattoo can cover part of a lesion and make changes less obvious, especially in case of recurrence¹⁴.
Tattoo ink may sometimes make it more difficult for a pathologist to spot skin cancer cells in a biopsy sample¹³.
Tattoo ink can hide or resemble changes (camouflage), such as new growths or bleeding, making them harder to recognise and diagnose¹⁵.

Note: Hence, it is better to avoid tattooing directly over moles or other spots that need regular monitoring.

When to Consult a Doctor?

Most tattoos cause some redness, tenderness or swelling while the skin heals⁶. However, symptoms that persist or become worse may indicate a complication. Consult your doctor for the following:

Redness, pain or swelling that continues to worsen or does not heal
Appearance of rashes (severe allergic reaction)
Symptoms of an infection such as fever, chills, shaking, or sweating
A bump or firm area developing within the tattoo⁶
A mole or other skin lesion showing unusual changes around a tattoo
Any unusual discharge, bleeding, or change in colour in the tattooed area¹⁴

Early medical evaluation might help identify infections, allergic reactions and other skin conditions that may need treatment.

Conclusion

According to current research, tattoos have not been proven to cause cancer. However, researchers are still learning about the long-term effects of tattoo ink. Choosing a trusted tattoo artist, making sure proper hygiene is followed and caring for your tattoo as it heals can help lower the risk of complications. It is important to keep an eye on your tattooed skin and get any unusual changes checked by a doctor.

Frequently Asked Questions (FAQs)

Can tattoo ink spread to lymph nodes?

According to several studies, some tattoo ink particles are said to move from the skin to nearby lymph nodes through the lymphatic system. Researchers have found these particles in lymph nodes, but their long-term effects on health are still not fully known¹.

Can tattoo ink cause cancer years later?

Some case reports have shown cancer development in individuals with tattoos soon after or years later after tattooing. Tattoo ink is said to contain certain salts and pigments which when acted upon by UV light might generate some products that may be toxic to body cells and genetic material, however, there is not enough evidence to confirm the relationship yet. Therefore, further research is needed to prove this claim^1,2.

Can tattoos hide the early signs of skin cancer?

Tattoo ink can sometimes hide early signs of skin cancer by covering or changing the look of moles and other skin spots. This can make changes in their colour, shape or edges harder to notice, so avoid tattooing over moles and check your tattooed skin regularly¹³.

Is it safe to get a tattoo if cancer runs in my family?

A family history of cancer does not mean you need to avoid tattoos. However, if skin cancer runs in your family, consider getting a skin check from a dermatologist first and avoid tattooing over moles or other spots that need regular monitoring¹³.

Can UV tattoos cause cancer?

There is no clear proof that UV tattoos cause cancer. However, some inks may change when exposed to UV light and produce harmful compounds¹.

Does removing tattoos cause cancer?

People often search for can laser tattoo removal cause cancer, but the answer is no. Tattoo removal has not been linked to cancer. However, removal can cause side effects such as redness, soreness, scarring, pinpoint bleeding, and infection¹⁶.

Generic Medicine List in India: A Guide to Common Generic Medicines

Introduction

Generic medicine is a medicine that contains the same active ingredient and is intended to provide the same therapeutic effect as its branded counterpart¹.

Many people prefer buying generic medicines as they are affordable. Generic medicines are receiving attention in India due to growing awareness of affordable healthcare options. This blog will cover what generic medicines are, common generic medicines in India, and tips to safely buy generic medicines in India, which helps in making informed choices.

Generic Names of Common Medicines in India by Health Condition

Generic medicines are medicines identified by their active ingredient and are used to treat or manage specific health conditions. In India, many commonly used medicines are included in the National List of Essential Medicines (NLEM), which identifies medicines considered important for meeting the country’s priority healthcare needs^1,2.

The appropriate medicine, strength, dose, and duration depend on your individual health condition and should be determined by your consulting doctor.

Why One Generic Medicine has Many Brand Names

A single medicine can have many brand names because several pharmaceutical companies might make the same generic medicine and give their products different brand names. The generic name refers to the active ingredient, while the brand name is chosen by the company that makes the medicine. For example, several companies may manufacture paracetamol and sell it under different brand names³¹.

The various available brands could look different, but the active medicine remains the same in case of the generic medicine. Regulatory authorities emphasize that an approved generic must have the same active ingredient, strength, dosage form, and route of administration as the corresponding brand name medicine, and must meet required standards for safety, effectiveness, and quality¹.

Another reason many brands exist is competition between manufacturers. Every brand gives its product a unique name to make it easier to recognise and remember. Authorities explain that multiple brands producing the same generic medicine can be approved, and this competition can actually help make medicines more affordable and improve access to treatment³².

Tips for Buying Generic Medicines Safely in India

Some of the tips to ensure safe generic medicine use in India:

Verify the label before buying: Verify the medicine name, strength, manufacturer, batch number, and expiry date on the pack. These details are covered under India’s drug labelling requirements².
Choose a reliable outlet: Choose a licensed pharmacy or a recognised Jan Aushadhi Kendra. Jan Aushadhi Kendras are part of the government programme established to provide quality generic medicines at affordable prices. The Government also reports on quality checks and testing for medicines supplied through these outlets³³.
Match the generic name with your prescription: Verify that the medicine and strength are the ones prescribed. Government guidance supports prescribing medicines by their generic names and promoting rational use³⁴.
Do not change treatment on your own: If you are considering replacing a prescribed branded medicine with a generic alternative, check with your doctor first. This helps ensure that the medicine and its use are appropriate for you³⁴.
Ask a doctor if unsure: If you are uncertain whether a generic medicine is the correct substitute for the medicine prescribed, check with your doctor first³⁴.

What’s Next for Generic Medicines in India?

Generic medicines are expected to remain an important part of India’s effort to make treatment more affordable and accessible. The Government’s Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) aims to increase access to quality generic medicines and promote their use among the public. Government reports also state that medicines supplied through Jan Aushadhi Kendras are generally priced about 50 to 80% lower than leading branded products, which can help reduce the cost of treatment^35,36.

However, wider use of generic medicines still faces challenges such as public acceptance, awareness, maintaining reliable availability and fighting counterfeit products. The Department of Pharmaceuticals specifically identifies the need to dispel the belief that low priced generic medicines are of inferior quality or less effective, while its reports also emphasise maintaining adequate medicine stocks. Continued awareness, efforts and improvements in supply and access will therefore be important for the future growth of generic medicines in India^35,37.

Conclusion

Generic medicines can offer an affordable way to access essential treatment opitions while containing the same active ingredients as their corresponding branded medicines. In India, government initiatives such as the Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) aim to improve access to quality generic medicines at affordable prices and reduce patients’ out of pocket healthcare costs. As awareness and access continue to grow, choosing medicines based on their active ingredient, strength, quality, and appropriate medical advice can help people make informed decisions about their healthcare choice.

Ear Discharge (Otorrhea): Common Causes, Warning Signs and Treatment

Introduction

Noticing fluid, pus, blood or any substance coming out of the ear can make anyone anxious. This type of ear discharge, which is medically known as otorrhea, can result from pathologic factors like ear wax or certain pathologic causes¹. Understanding the causes of otorrhea can help in taking appropriate decisions regarding the severity of the condition and whether a medical intervention is needed. In this blog, we will cover what otorrhea is, its types, causes, symptoms, treatment and preventive measures that could be taken.

What Is Ear Discharge (Otorrhea)?

Any fluid or substance draining from the ear is termed as ear discharge or otorrhea. Mostly ear discharge is considered a sign of some underlying conditions rather than being a disease itself. It can result following certain infections, injuries, and some tissue growths¹. The symptoms can vary based on the underlying condition that led to discharge, and can include pain, fever, dizziness, ringing in the ears etc. However, untreated discharge cases can lead to several complications, including hearing loss and spread of the infection to surrounding structures².

Did You Know?

Acute otitis media is considered the second most common diagnosis in the emergency department of children and can show symptoms of pain along with discharge³.
15-20% of affected children with acute middle ear infections (acute otitis media) develop ear discharge due to the perforation of the eardrum⁴.
External ear infection (otitis externa), which is a major cause of discharge, is found to be affecting 10% of people at some point during their lifetime³.
The most commonly isolated organism in otitis externa is Pseudomonas aeruginosa, in chronic otitis media is Staphylococcus aureus and in acute otitis media is Streptococcus pneumoniae⁴.

Types of Ear Discharge

Based on the consistency, colour and appearance, ear discharges can be of five types⁴. Recognising the different types can help in reaching the diagnosis promptly and initiating appropriate interventions.

Clear: A clear, transparent discharge might point towards any injuries to the head. It is caused by the leakage of cerebrospinal fluid (CSF) through the ear⁴.
Bloody: It can be a discharge with blood appearing red or pink and can occur as a result of any injuries or trauma to the ear or head⁴.
Serous: Thin, watery, non-pus-containing discharge is seen in certain kinds of middle ear infection with effusion (otitis media with effusion-OME)⁵. It can result following a sudden decrease in ear pressure compared to the air pressure⁶.
Mucoid: Thicker, sticky fluid (mucous) discharges can be seen in mucoid type OME⁵. This condition is also termed “glue ear” occurs due to the accumulation of certain kinds of mucins⁶.
Purulent: Thick discharge containing pus, which is seen in external ear infections and suppurative middle ear infections⁵. It can be thick, opaque or white or yellowish in colour and may bear an unpleasant smell in some cases.

Causes of Ear Discharge

Ear discharge causes are mainly pointing towards any underlying infections, past injuries or procedures done in the ear.

Ear Wax: In most cases, the discharge would be ear wax⁷. It is considered a normal protective mechanism of the ear from dust particles. However, overaccumulation might lead to some difficulties.
Ruptured Eardrum: White, yellow or bloody discharges are commonly associated with a ruptured eardrum. Causes of rupturing can include:
- Any foreign objects in the ear: This usually happens in children when they put any toys or foreign objects into the ear. The discharge might contain pus and blood^1,7.
- Pushing an object into the ear: Pushing cotton buds or any objects might lead to the rupture of the eardrum^1,7.
- Injuries, sudden changes in air pressure such as during air travel and exposure to very loud sounds might cause rupture⁷.
- Middle Ear Infection: Infection can increase the risk of fluid buildup in the ear, which induces increased pressure and can lead to the eardrum rupturing. Though middle ear infections commonly occur in children, people of any age can face this condition. It is often associated with severe pain and a thick yellowish discharge. When a ruptured eardrum takes time to heal, discharge can be seen continuously without any pain¹.
Outer Ear Infection: It is also termed swimmer’s ear. Skin inside the ear canal can swell and cause discharge¹. In addition, the ear canal can be reddish and moist, itchy, with pain that increases during the movement of the earlobe⁷. Sometimes fungal infections can also give rise to sticky ear discharge along with ear pain⁸.
Eczema: A type of skin allergy or irritation which can lead to clear discharge¹.
Abnormal skin cells: An abnormal collection of skin cells, called cholesteatoma, can induce a foul-smelling discharge¹.
Head injury: A serious injury can lead to the leakage of brain fluid (cerebrospinal fluid) through the ear, which can be clear or with blood. It is an emergency situation, and immediate medical attention is needed¹.
Following an ear tube insertion: A tube (grommet) inserted through the eardrum might produce ear discharge after the procedure⁸.

Symptoms of Ear Discharge

Ear discharge symptoms can vary based on the causes of discharge and include:

Pain: Ear pain (otalgia) is considered the indicator of acute cases of middle ear infection³.
Hearing Loss: Hearing loss is mostly seen in middle ear infection with discharge cases along with a sensation of fullness⁶. It can also be seen in cases of cholesteatomas⁹.
Dizziness and Ringing in the ears: Dizziness and ringing in the ears are pronounced in cases of cholesteatomas along with foul-smelling discharges⁹.
Fever: Fever is marked in the acute cases of middle ear infection¹⁰.

Ear Discharge in Children vs Adults

Ear discharge in adults	Ear discharge in children
In adults, external ear infection is more common compared to children, along with acute middle ear infection and perforation of the eardrum³.	In children, the most common cause of discharge is middle ear infection, most commonly in the age group of 6 to 24 months³.
In adults, symptoms of an infection can include itchiness, irritation, a sense of fullness in the ear, pain and ear discharge¹¹.	Children might show signs of any infection by rubbing or pulling the ear, being irritable, avoiding foods and losing their balance¹¹.
Ear discharge in adults resolves based on the underlying causes. In cases of middle ear infections, oral antibiotics only provide a slight reduction of symptoms. In most cases, ear drops are preferred, provided there is no history of any other underlying diseases⁸.	In most cases of ear discharge in children, spontaneous resolution can be seen within one week¹². Oral antibiotics are most beneficial in children having middle ear infection in both ears and who are aged more than 2 years⁸.
For treatment of ear discharge in adults with chronic suppurative otitis media (CSOM), topical antibiotics alone or along with other topical steroids are recommended. Ear cleansing can also be beneficial¹³.	For treatment in children with CSOM, topical antibiotics are preferred over antiseptics. Limited evidence is present regarding the benefits of ear cleansing, though it is usually recommended for children¹³.

How Is Ear Discharge Diagnosed?

Diagnostic procedures mainly focus on a detailed history and examination to determine the underlying cause. Other tests are done if there is uncertainty in cause or more serious conditions are suspected.

Medical history: History of any associated pain, hearing loss, duration and frequency, colour and consistency of discharge can help in identifying the cause of the discharge. History of any trauma or surgeries or grommet insertion can also be beneficial in identifying the cause⁸.
Otoscopy: It is an instrument used by doctors to look into the ear, and they can find what is causing the discharge¹. This is helpful in examining the external auditory canal and eardrum. Also, the middle ear can be examined in case of an ear drum perforation. It can help in finding whether the discharge is due to any foreign bodies, infection of the outer or middle ear, trauma or any perforations of the eardrum¹⁴.
Hearing Test: It can help determine whether the discharge and the underlying cause is affecting hearing¹.
Culturing of the discharge: If fungal infections are suspected based on the itchiness (pruritus) or fungal parts (hyphae) during the examination, a swab is taken for culturing of the organism and identifying the effective medicine (sensitivity). In case of a bacterial infection which is not resolving with antibiotic treatment, culture and sensitivity from ear discharge can provide important information about the infection and further management⁸.
Imaging Tests: Imaging tests such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are helpful in diagnosing the cause of ear discharge¹. CT is helpful in assessing middle ear diseases such as cholesteatoma, or any abnormalities related to the skull. MRIs are helpful in finding any abnormalities in the structures present inside the skull or soft tissue masses⁶.

Treatment of Ear Discharge

Ear discharge treatment can vary based on the underlying cause, and it can be⁸:

Treatment for outer ear infection
- Topical medicines: Antimicrobials containing steroids are effective in the treatment. However, if any fungal infection is suspected, preparations which target both bacteria and fungi can be given.
- Oral antibiotics: If there are no signs of any underlying systemic infections, oral antibiotics are not needed. However, if the infection has spread to the skull base, systemic antibiotics might be needed to control the spread of infection.
- Suctioning of debris from the ear: If no improvement in symptoms is noted, referring to an ENT specialist is recommended for aural microsuction. Here, any discharge or debris is removed by suction under magnification.
Treatment for middle ear infection: Middle ear infections may resolve spontaneously within 24 hours.
- Medicines: Children who are older than 2 years are put under observation for 2-3 days to check whether symptoms are resolving, and during this period only pain-relieving medicines are needed. Oral antibiotics are advised for children aged <2 years who have middle ear infections in both ears with ear discharge.
- Antibiotic eardrops: If the patient has no underlying diseases and the only concern is discharge through the perforated eardrum, topical antibiotics are preferred over systemic ones.
- Intravenous antibiotics: Persistent pain even after the oral antibiotic therapy needs to be assessed, and it might indicate infection of a bone behind the ear (mastoiditis). In these cases, intravenous antibiotics might need to be considered to prevent the infection from developing into infections affecting bone (osteomyelitis) and abscess formation.
Treatment for grommet-associated discharge: Ear drops containing antibiotics and microsuction are generally used in grommet-associated discharge. However, there is less evidence regarding the most effective treatment for this.
Treatment for cholesteatoma: Surgery is preferred in this condition to remove the abnormal tissue from the ear.
Treatment for cerebrospinal discharge: CSF ear discharge often precedes a history of any injuries. This should be managed following an urgent investigation.

Keeping the ears dry and avoiding inserting foreign objects such as cotton tips are also part of the otorrhea treatment, as they can help in preventing the further progression of the condition. A persistent, foul-smelling discharges needed to be assessed by a medical practitioner. Also, use of eardrops without proper medical attention might do danger to your health.

Home Care Tips for Ear Discharge

Home care tips that can help for ear discharge depend on the cause and symptoms of the discharge⁸:

Keep the ears dry: Avoiding any instances that might wet the ears can help in minimising further irritation.
Avoid inserting any objects into the ear: Poking any objects into the ear might complicate the condition and needs to be avoided.
Avoid swimming: Swimming might lead to deterioration of the condition by wetting the ears. Also, if there is any chance of splashing water into the ear, petroleum jelly-coated cotton wool can be used.
Clean ear with a wick: A soft and strong tissue paper can be made into a wick and can be inserted into the ear canal. Placing it in there for one minute can absorb the excess discharge, and then it should be removed. Another fresh wick is inserted, and the procedure is repeated till it becomes dry².

Possible Complications of Untreated Ear Discharge

Untreated ear infections along with the discharge can lead to complications, including²:

Hearing loss
Persistent drainage
Rupture/Perforation of eardrum
Dizziness
Balance Disorders
Swelling behind the ear
Infections spreading to the brain

Tips to Prevent Ear Discharge

The following general preventive measures can be taken to avoid ear discharge:

Maintaining ear hygiene along with drying ears after a water bath are most helpful in preventing discharge associated with ear infections. Try to keep the ears as dry as possible by using towels or tilting the head back and forth to naturally allow the draining.
Keeping ears dry while and after swimming is important to avoid frequent ear infections. Use custom earplugs or tight fit shower caps to protect ears while swimming.
Exclusive breastfeeding for 6 months and continuing at least for 12 months can help in preventing some ear infections and the associated discharge¹⁵. Keep the baby in slanting position while breastfeeding to avoid ear discharge¹⁶.
Avoiding smoking can prevent infections and related discharge¹⁵.
Avoiding putting any external objects into the ear and forcefully removing the earwax is important¹⁷. If you feel any discomfort because of the accumulation of earwax, contacting your healthcare professional is advised.
Flu and pneumococcal vaccines are advised as a preventive measure against middle ear infections. Since a bacterium named Streptococcus pneumoniae is the most common cause of middle ear infection, vaccination against this may help in the prevention of the infections¹⁵.
Fungal infections can result following wounds caused by continuous rubbing or insertion of any wooden sticks or metal wax picks into the ear to remove earwax. Coconut oil application is also found to be a predisposing factor to fungal infection. These practices should be avoided to prevent the discharge related to fungal infections¹⁸.

When Should You Consult a Doctor?

Consultation with a doctor is recommended in the following instances⁷:

If the ear discharge is associated with severe pain.
Fever or headaches are seen along with the discharge.
White, yellow, clear or bloody ear discharge.
Any previous history of trauma prior to the discharge.
If the discharge persists for more than five days.
In doubtful cases of hearing loss.
Any signs of swelling or redness from the ear.

Immediate medical attention is required if external ear infections are associated with weakness of nerves of the brain (cranial nerve palsy) as this might indicate bone involvement. Additionally, in individuals having compromised immunity such as diabetics, ENT consultation is important if there is presence of small, red, easily bleeding tissues (granulation tissue) that formed in the ear canal, along with redness and swelling of the outer ear or deteriorating symptoms⁸.

Conclusion

Ear discharge or otorrhea is the drainage of fluid or any substance from the ear. Causes of otorrhea mostly involve ear infections, inserting any foreign objects into the ear, injuries or a previous history of any procedures or surgeries related to the ear. Otorrhea symptoms can vary based on the underlying causes and can include pain, sensation of fullness, hearing loss, fever, along with discharge. Though most cases can be managed effectively, understanding about otorrhea can help in avoiding unnecessary concerns and taking appropriate measures.

Frequently Asked Questions (FAQs)

How is the cause of ear discharge diagnosed?

Diagnosis of ear discharge is mainly based on a detailed medical history and physical examination. Any past history of injuries, swimming, surgeries, or hearing changes is noted. An otoscope is used to check the ear canals and eardrum. Hearing tests or imaging tests such as CT and MRI are needed based on the findings¹.

What causes yellow or green discharge from the ear?

Yellow or green discharge might contain pus and is usually associated with underlying ear infections. In purulent middle ear infections, the discharge can be yellow with pus¹¹. In cases of rupture of the eardrum, white, yellow or bloody discharges can be seen⁷. However, the colour of the discharge might not point towards a particular condition. A medical evaluation is required to find the exact cause.

Can earwax be mistaken for ear discharge?

Yes. Earwax can sometimes be mistaken for discharge, especially when it is darker, soft and excessive. Earwax is a normal substance that is produced by the ear to protect the ear from dust particles⁷. However, if the earwax accumulation causes any discomfort and foul smelling medical attention is needed.

Is ear discharge contagious?

Ear discharge is not contagious. Discharges associated with external ear infection or middle ear infection don’t spread from person to person^3,10.

Can ear discharge go away on its own?

Remission of the ear discharges are depended on the underlying causes. In most cases of middle ear infections, spontaneous remission happens within one day. And in the absence of any underlying systemic diseases, only ear drops are needed in most cases. Children under 2 years of age and those having infections in both ears benefit more from oral antibiotics⁸.

Can swimming cause ear discharge?

Swimming put at an increased risk for ear discharge due to more chances for external ear infection. Keeping the ears dry after swimming or using any cotton plugs to avoid splashing of water into the ear can be followed as a preventive measure against ear discharge caused by this⁸.

Can a ruptured eardrum cause ear discharge?

Yes. Rupturing of the eardrum caused by injuries due to any foreign objects that are inserted into the ear, pushing materials into the ear, sudden pressure changes as during air travel and middle ear infections can all cause ear discharge⁷.

What Level of Eosinophils Indicates Cancer?

Introduction

Seeing a high eosinophil count on a blood test can feel worrying, especially if you are unsure what it means. A raised eosinophil count is not always dangerous, but it can be a clue that something else is happening in the body. Common causes include allergies, asthma, some infections, reactions to medicines, and, less often, certain cancers. Understanding what eosinophils do, what counts as a normal or high level, why levels can rise, how doctors investigate the cause, and when to seek medical care can help reduce unnecessary worry and support informed decisions.

What Are Eosinophils?

Eosinophils are a type of white blood cell that helps the immune system respond to allergies, asthma-related inflammation, and some infections, especially parasitic infections. White blood cells include several groups. Eosinophils belong to a group called granulocytes because they contain tiny enzyme-filled granules that help them take part in immune responses¹.

Did You Know?

Eosinophils are made in the bone marrow. Once in the blood, they usually circulate for about 8–18 hours, and they can remain in body tissues for several days to weeks, especially in inflammatory conditions².
Eosinophil levels can naturally rise and fall during the day. In people with normal counts, levels are often highest around 1 am and lowest around noon, which is because eosinophils increase at nighttime and decrease during daytime³.
Worldwide, parasitic infections are a common cause of eosinophilia. In many developed countries, reactions to medicines are among the most common causes³.

Normal Eosinophil Range

The absolute eosinophil count is the number of eosinophils in a specific volume of blood. It is usually calculated from a complete blood count by combining the total white blood cell count with the percentage of eosinophils.

A typical normal eosinophil range is about 0–500 cells per microlitre of blood. The exact reference range may vary slightly by laboratory, so it is important to interpret the result using the range printed on your own report⁴.

High Eosinophil Levels and Eosinophilia

Eosinophilia means that eosinophil levels are higher than expected in the blood. Many sources define eosinophilia as an absolute eosinophil count above about 450–550 cells per microlitre, although the exact cut-off can vary by laboratory².

Based on the counts of eosinophils, eosinophilia can be divided into mild, moderate, and severe:

Mild Eosinophilia: 500–1500/microlitre
Moderate Eosinophilia: 1500-5000/microlitre
Severe Eosinophilia: >5000/microlitre

A persistently high absolute eosinophil count above 1,500 cells/microlitre, especially when confirmed on repeat testing, requires a thorough medical evaluation. If doctors rule out common secondary triggers, such as allergies or infections, and find evidence of organ or tissue damage, this pattern may point to hypereosinophilic syndrome (HES). Doctors use clinical findings and additional tests to decide whether this diagnosis applies⁵. Earlier, HES was suspected only if these symptoms lasted for at least 6 months. However, HES is now considered a valid diagnosis if there is clear evidence of organ injury, regardless of how long the symptoms have lasted.

Causes of Elevated Eosinophil Levels

Eosinophilia may be because of primary or secondary factors.

Primary Causes of Eosinophilia

When high eosinophil levels are because of abnormal growth of blood-forming cells in the bone marrow, doctors identify the condition as primary (or intrinsic) eosinophilia. Such primary causes include:

Chronic eosinophilic leukaemia: It is a rare type of blood cancer characterised by increased levels of eosinophils in blood, bone marrow, and tissues⁶.
Hereditary eosinophilia: Persistent eosinophilia caused by an inherited condition in families⁷.
G syndrome: Repeated episodes of high eosinophil count associated with swelling (angioedema) are seen. Repeated episodes of fevers, itching, and swelling can be seen².

Secondary Causes of Eosinophilia⁵

When any other underlying conditions or diseases cause eosinophilia, they are referred to as secondary causes:

Allergic diseases: Asthma, drug allergies, food allergies, drug rash with eosinophilia and systemic symptoms (DRESS) syndrome
Parasitic infections: Mostly by ancylostomiasis, ascariasis, schistosomiasis, toxocariasis
Bacterial and fungal infections: Scarlet fever, allergic bronchopulmonary aspergillosis, coccidiomycosis, histoplasmosis
Skin diseases: Atopic dermatitis, eczema, pemphigus, Sezary syndrome

Symptoms Associated with High Eosinophils

While eosinophilia itself does not cause any symptoms, they may be because of the underlying causes⁸:

General: fatigue and fever
Skin-related: itching and swelling on the face
Respiratory: cough, difficulty in breathing and symptoms of an inflamed nose (rhinitis)
Gastrointestinal: diarrhoea (with or without blood in stools), vomiting, difficulty in swallowing, and regurgitations
Neurological: abnormal sensations
Muscles and bone-related: muscle pain
Heart-related: Symptoms related to heart failure

Eosinophilia itself can show symptoms when it invades tissues or causes any organ injuries, especially in cases of HES.

What Level of Eosinophils Indicates Cancer?

There is no single eosinophil number that automatically means cancer. Doctors consider cancer only when eosinophilia is persistent, common causes have been ruled out, the count does not improve after treating a likely cause, or other warning signs are present. Eosinophilia can occur with some blood cancers, such as leukaemia and lymphoma, but these are more likely to be suspected when there are additional findings, such as abnormal white blood cell counts, low haemoglobin, low platelets, swollen lymph nodes, or an enlarged spleen or liver. Eosinophilia has also been reported with some solid tumours, including cancers of the lung, breast, cervix, kidney, ovary, prostate, and melanoma, but this is less common⁹.

However, cancers can be considered in the presence of certain symptoms such as enlarged lymph nodes (lymphadenopathy) and spleen (splenomegaly), abnormal blood counts¹⁰, unexplained weight loss, general symptoms, or persistent eosinophilia.

Cancers Associated with High Eosinophil Levels

Eosinophilia linked with cancer can happen in two broad ways. In rare cases, the cancer arises from eosinophil-producing blood cells, such as eosinophilic leukaemia. In other cases, eosinophils rise as part of the body’s response to another cancer. Cancers associated with eosinophilia may be grouped as blood-related cancers or solid-organ cancers².

Blood-Related Cancers²
- Chronic eosinophilic leukaemia^6,11
- Lymphomas (T-cell lymphoma and Hodgkin Lymphoma)¹²
- Chronic myelomonocytic leukaemia

Organ-Associated Cancers²
- Cancers of gastrointestinal tract
- Lung cancer
- Cancers related to cervix, vagina, penis, skin, and bladder
- Thyroid cancer

How Doctors Diagnose the Cause of High Eosinophils?

The extent of diagnostic tests to find the cause of high eosinophils depends on the severity of the symptoms, any suspected causes, and whether there is any organ involvement.

Medical history: Doctors ask about symptoms, how long the eosinophil count has been high, recent or long-term medicine use, allergies, rashes, fever, night sweats, weight loss, travel, work or environmental exposures, and possible infection risks. Questions about travel and diet, such as eating raw or undercooked freshwater fish or crayfish, can help identify some parasitic infections^5,13,14.
Physical examination: The doctor may check the skin, listen to the lungs for wheezing, examine the abdomen for an enlarged liver or spleen, and feel for swollen lymph nodes^5,13.
Laboratory tests: Common tests include a complete blood count with differential, blood chemistry tests, inflammatory markers such as erythrocyte sedimentation rate or C-reactive protein, vitamin B12, and sometimes serum tryptase, IgE levels, allergy tests, or infection tests depending on the person’s history.
Checking for organ involvement: If symptoms suggest organ involvement, doctors may recommend tests such as a chest X-ray, oxygen saturation measurement, heart tests such as an echocardiogram, or blood tests such as troponin³.
Testing for parasitic infections: Depending on your travel background, living environment, and specific exposure history, doctors will order focused parasite testing. This often includes blood tests (serology) and stool examinations to check for Strongyloides infection, as well as targeted blood tests to rule out infections caused by other worms like Toxocara or Schistosoma^15,16.

If these steps do not identify a clear cause, or if the results raise concern for a blood disorder or cancer, doctors may recommend more specialised tests.

Bone marrow examination: Bone marrow biopsy and aspirate are useful in finding any blood-related cancers (haematologic malignancies), spreading cancers (metastasis), or other infections. It is beneficial in evaluating blood-related or clonal disorders, especially in the presence of persistent eosinophilia, abnormal blood cell counts, enlarged spleen, or suspicion of a myeloid cancer.
Flow cytometry: This is beneficial in finding the abnormalities related to immature blood cells (blasts) and T-cells, which might cause some cancers. However, it does not help diagnose all eosinophilia-related cancers, and it cannot, by itself, prove that eosinophilia is because of abnormal bone marrow cells.
Immunohistochemistry: It helps find the number and type of the blast cells with the use of special stains. It can be beneficial in ruling out some other diseases, such as Hodgkin lymphoma.
Cytogenetics: Screening for certain changes in genetic material (DNA) is done.
Molecular testing: When earlier tests fail to identify the genetic abnormalities, molecular testing is done. Genes are examined for small changes using advanced next-generation sequencing. However, findings derived from these cannot directly indicate the presence of cancer and need to be correlated with clinical symptoms and other diagnostic tests¹³.

Treatment Options for High Eosinophil Levels

Treatment for high eosinophils depends on the cause, the level of the count, symptoms, and whether any organs are affected. The goal is usually to treat the underlying condition and prevent organ damage.

Conservative management: In mild cases of eosinophilia with no specific symptoms of any organ damage, conservative management involving regular monitoring is enough⁵.

Treating the underlying causes³
- Infections: If a parasite is the cause, antiparasitic medications may lower the eosinophil count as the infection is treated.
- Medication-induced: Stopping or changing the suspected medicine, under medical guidance, is often the main step. Mild skin symptoms may be treated with creams or ointments, while reactions that affect organs may need higher-dose steroids and closer monitoring.
- Allergic conditions: Conditions such as eczema, allergic rhinitis, and asthma may be treated with inhaled, topical, or oral corticosteroids, depending on severity. Some people with eosinophilic asthma may benefit from newer medicines that specifically reduce eosinophil-driven inflammation.
- Autoimmune or immune-related disorders: Treatment focuses on controlling the underlying immune condition.
- Cancers: When eosinophilia is linked to cancer, treating the cancer may reduce the eosinophil count³.
- Corticosteroids: In eosinophilic cases with organ damage, especially in certain forms of HES or severe eosinophilia-associated inflammatory diseases, steroids are given intravenously.
- Other medicines or procedures: In severe forms of the disease, medicines targeting specific cells (cytotoxic agents) and procedures such as stem cell transplants are recommended, but eosinophilia can also occur after some cancer treatments, including stem cell transplant⁵.

When Should You See a Doctor?

Speak with a healthcare professional if your eosinophil count is repeatedly high, if you have symptoms such as fever, weight loss, night sweats, breathing problems, rash, swelling, diarrhoea, or chest symptoms, or if you recently travelled to an area where parasitic infections are common. You should also seek medical advice if the result is new and you are unsure whether it needs follow-up.

Conclusion

A high eosinophil count can have many causes, including allergies, asthma, infections, autoimmune or immune-related diseases, reactions to medicines, and, less commonly, cancer. The count alone does not usually identify the cause. Doctors interpret eosinophil levels alongside symptoms, medical history, examination findings, and other test results. Knowing what high eosinophils mean can help you understand your report, ask informed questions, and seek timely medical advice when needed.

Frequently Asked Questions (FAQs)

Why are my eosinophils high?

Eosinophilia can happen for many reasons, including allergies, asthma, infections, some autoimmune or immune-related diseases, certain skin conditions, medicine reactions, and, less commonly, cancer. The cause can usually be identified only by comparing the blood test result with your symptoms, medical history, examination findings, and other test results⁵. Your healthcare professional can help determine the most likely cause in your case.

Can you live with high eosinophils?

Mild cases of eosinophilia might not produce any symptoms, and only conservative management might be enough. However, more severe cases of eosinophilia or those associated with any organ damage might need to be evaluated by a healthcare professional⁵.

Can fatty liver cause high eosinophils?

Eosinophils related to liver diseases might be a result of some protective mechanism following some conditions. They can include viral or parasitic infections, drug-induced liver injuries, or other immunity-related liver diseases¹⁷.

Can skin cancer cause high eosinophils?

Eosinophilia might not be a typical feature of skin cancers. However, in some cases of skin cancers such as melanomas⁹, eosinophilia can be seen.

Does a high eosinophil count always mean cancer?

No. A high eosinophil count does not automatically mean cancer. Cancer is only one possible cause, and many non-cancer causes are more common. Doctors may investigate for cancer if eosinophilia is persistent, common causes have been excluded, the count does not improve after treatment for a likely cause, or other warning signs are present⁹.

Can eosinophilic esophagitis cause cancer

Eosinophilic oesophagitis is an inflammatory condition of the oesophagus. Current evidence does not show a strong link between eosinophilic oesophagitis and cancer, although rare cases of oesophageal cancer have been reported in people with this condition¹⁸.

Throat Cancer: Symptoms, Causes, Diagnosis & Treatment

Introduction

A sore throat that keeps coming back, hoarseness that does not improve, trouble swallowing, or a lump in the neck can naturally make you worry about throat cancer. These symptoms often have causes other than cancer, but persistent or worsening changes should not be ignored¹. Learning about the types, symptoms, causes, risk factors, diagnosis, and treatment of throat cancer can help you recognise warning signs early. Knowing when to seek medical advice may also support earlier detection and better treatment outcomes.

What Is Throat Cancer?

Throat cancer refers to cancer that develops in the throat (pharynx) or voice box (larynx). The throat is the passage behind the nose and mouth that leads to the food pipe and windpipe. Cancer can start in different parts of this area, including the tonsils, the base of the tongue, or the voice box¹.

Did You Know?

Throat cancer is part of a larger group of head and neck cancers¹.
Tobacco and heavy alcohol use are major risk factors for throat cancer².
Most throat cancers develop from the thin cells lining the throat and nearby areas, known as squamous cell carcinoma³.
Throat cancer may not show any symptoms at an early stage¹.

Types of Throat Cancer

Cancer can develop in several parts of the throat. The main types are named after the area where the cancer starts:

Nasopharyngeal Cancer: This cancer begins in the nasopharynx, the upper part of the throat located behind the nose.
Oropharyngeal Cancer: This develops in the oropharynx, the middle part of the throat. It may involve the tonsils, the back of the tongue, or the soft palate.
Hypopharyngeal Cancer: This starts in the hypopharynx, the lower part of the throat located above the food pipe and behind the voice box⁴.
Laryngeal Cancer: This cancer starts in the larynx, also called the voice box. It may develop above the vocal cords, on the vocal cords, or below them⁵.

Stages of Throat Cancer

The stage of throat cancer helps doctors describe how large the cancer is and whether it has spread. Staging can differ depending on the part of the throat affected, so the points below are a general guide rather than a substitute for a doctor’s explanation.

Stage 0: Abnormal cells are present in the lining but have not invaded deeper tissues. This is also called carcinoma in situ⁵.
Stage I: The cancer is small and remains in the area where it started. It has not spread to nearby lymph nodes or distant organs.
Stage II: The cancer is larger than in stage I but is still usually limited to the throat area and has not spread to nearby lymph nodes⁶.
Stage III: The cancer is more advanced. It may be larger, may have grown into nearby tissues, or may have reached one or more lymph nodes in the neck^5,6.
Stage IV: This is the most advanced stage. The cancer may be any size and may have spread extensively into nearby structures, affected several lymph nodes, or travelled to different parts of the body (such as lungs or bones). Stage IV may be further divided into IVA, IVB and IVC, depending on the location and spread of the cancer^5,6.

Note: These are general descriptions. The exact meaning of each stage varies between cancers of the nasopharynx, oropharynx, hypopharynx and larynx. HPV-related oropharyngeal cancers also have a different staging approach from some other throat cancers.

Symptoms of Throat Cancer

Throat cancer symptoms depend on where the cancer starts and how advanced it is. Some symptoms are common and can be caused by less serious conditions, but symptoms that persist should be checked by a doctor. Possible symptoms include:

A sore throat that does not improve
Persistent hoarseness or a change in voice
Pain or difficulty while swallowing
A lump or swelling in the neck or throat
Unexpected weight loss
Persistent cough
Blood in saliva or phlegm
A blocked nose that keeps coming back or frequent nosebleeds¹
Ear pain without a reason⁷

Causes of Throat Cancer

Throat cancer develops when cells in the throat or voice box change and begin to grow in an abnormal, uncontrolled way. There is usually no single cause. Instead, several factors can increase the chance of these cell changes.

Tobacco Use: Smoking and smokeless tobacco can damage cells and cause cancers affecting the throat and larynx⁴.
Heavy Alcohol Use⁴^,5: Regular heavy alcohol use can irritate and damage the tissues of the throat and may contribute to cancer-related cell changes.
Human Papillomavirus (HPV) Infection: Certain high-risk HPV types, particularly HPV-16, are associated with oropharyngeal cancer.
Betel Quid and Areca Nut: Chewing betel quid or areca nut can increase the risk of cancers of the mouth and throat. The risk is higher when betel quid is used with tobacco⁴.

Risk Factors

A risk factor is something that increases the chance of developing a disease. Having a risk factor does not mean a person will develop throat cancer, but it can make the condition more likely. Important risk factors include:

Age: The chance of developing throat cancer generally rises as people get older. Laryngeal and hypopharyngeal cancers are more commonly reported in people over 65 years.
Sex: Throat cancers are diagnosed more often in men than in women. This difference is partly linked to patterns of tobacco and alcohol use, although risk can vary from person to person.
Diet: Eating very few fruits and vegetables may be linked with a higher risk of some head and neck cancers. A balanced diet supports overall health, although diet alone cannot prevent throat cancer⁸.
Workplace Exposure: Long-term exposure to substances such as wood dust, formaldehyde, asbestos, nickel, or certain industrial chemicals may increase the risk of some head and neck cancers. People working around dust, fumes, or chemicals should follow workplace safety guidance^8,9.
Inherited Genetic Conditions: Rare syndromes such as Fanconi anaemia and dyskeratosis congenita can significantly increase the risk of developing head and neck cancers, including cancers of the throat, at a younger age⁸.
Poor Oral Health: Long-term problems with oral hygiene and dental health may be associated with a higher risk of pharynx and larynx cancers.¹⁰
Previous Cancer History: People who have had head and neck cancer may have a greater chance of developing another cancer in regions such as the oropharynx, hypopharynx, and larynx⁴.

Note: A person can have one or more risk factors and never develop throat cancer. A person can also develop throat cancer without any known risk factors. If you notice possible warning signs, speak with a doctor for proper evaluation.

Diagnosis

Throat cancer diagnosis usually involves checking the throat and neck, looking closely at the affected area, and confirming the diagnosis with a tissue sample if needed. The tests used depend on the symptoms and the part of the throat involved.

Medical History: The doctor asks about symptoms, how long they have been present, tobacco or alcohol use, previous illnesses, diet, family history, and other factors that may affect risk or treatment.
Physical Examination: The throat and mouth are examined for unusual areas, swelling or lumps. The doctor may also examine the neck to check for enlarged lymph nodes¹¹.
Blood Tests: Blood tests do not diagnose throat cancer by themselves. They may be used to check overall health, including blood cell counts and liver and kidney function, especially before treatment¹².
Imaging Tests: Imaging tests such as CT scans, MRI scans, or PET scans create detailed pictures of the throat, neck, and nearby tissues. These tests can help doctors understand the size of the cancer and whether it may have spread. A barium swallow X-ray may be used when swallowing problems need further assessment.
Biopsy: If an unusual area is found, the doctor may remove a small tissue sample and send it to a laboratory. A biopsy is usually needed to confirm whether cancer cells are present¹¹.

Note: Depending on the suspected cancer type, the doctor may recommend HPV testing or other laboratory tests on the biopsy sample. These results can help classify the cancer and guide treatment choices.

Treatment Options

Throat cancer treatment depends on the cancer type, location, stage, tumour size, overall health, and whether the cancer has spread. A care team may recommend one treatment or a combination of treatments.

Surgery: Surgery removes cancer tissue. The amount removed depends on where the cancer is and how far it has grown. In some cases, surgery may affect speech, swallowing, or breathing, so rehabilitation and supportive care may be part of recovery.
Radiation Therapy: Radiation therapy uses high-energy beams, such as X-rays, to damage and destroy cancer cells. It may be used on its own for some cancers or combined with surgery, chemotherapy, or other treatments.
Chemotherapy: Chemotherapy uses medicines that kill cancer cells or slow their growth. It may be given with radiation therapy or used when cancer is advanced, has returned, or has spread.
Targeted Therapy: Targeted therapy uses medicines that act on specific features of cancer cells. These medicines may be used for certain cancers, sometimes along with radiation therapy or other treatments.
Immunotherapy: Immunotherapy helps the immune system recognise and attack cancer cells. It may be considered for some advanced or recurrent throat cancers⁵.

Note: Treatment may also include supportive care to help with swallowing, nutrition, speech, pain and other treatment-related effects.

How to Prevent Throat Cancer?

Throat cancer cannot always be prevented, but reducing known risks can lower the chance of developing it. The following steps may help reduce risk:

Avoid smoking and using tobacco products such as cigarettes, beedis or chewing tobacco.
Avoid heavy or frequent alcohol use. If you drink alcohol, ask your doctor what amount is safe for you.
Ask your doctor about HPV vaccination. HPV vaccines help prevent infection with HPV types linked to several cancers, including some cancers of the throat⁴.
Include plenty of fruits, vegetables and other nutritious foods in daily meals⁸.
Use appropriate protective equipment and follow workplace safety measures if your job involves dust, fumes or chemicals^8,9.
Maintain good oral health by brushing regularly and getting regular dental check-ups¹⁰.
Seek medical advice if you notice throat symptoms that persist or keep returning, rather than ignoring them.

Note: These measures may lower risk, but they cannot guarantee complete prevention. A doctor or dentist should evaluate persistent, unusual, or worsening throat symptoms.

When to Consult a Doctor?

See a doctor if you have a sore throat, hoarseness, swallowing problems, or other throat symptoms that last for several weeks or keep coming back without a clear reason. Seek medical attention promptly if you notice a neck lump, unexplained weight loss, persistent ear pain, or blood in saliva or phlegm^1,7. These symptoms can have many causes and do not necessarily mean cancer but getting them checked can help identify the problem early.

Conclusion

Throat cancer can appear in different ways, and its symptoms may resemble those of less serious conditions. Persistent throat changes, voice changes, swallowing problems, or a neck lump should be assessed by a doctor. Knowing the warning signs and reducing avoidable risks may help with earlier detection and timely treatment.

Frequently Asked Questions (FAQs)

What is the survival rate for throat cancer?

Survival rates vary by cancer type, stage, overall health, and response to treatment. For example, US data report a 5-year relative survival rate of 62.5% for laryngeal cancer¹³. Some Indian studies have reported lower 5-year survival rates for laryngeal cancer, but these figures may reflect differences in stage at diagnosis, access to care, and study methods¹⁴.

Is throat cancer treatable?

Yes. Throat cancer can often be treated, and treatment is usually more effective when cancer is found early. The treatment plan may include surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, or a combination of treatments, depending on the cancer type and stage^4,5.

What does throat cancer feel like?

Throat cancer may cause a sore throat that does not improve, pain or difficulty when swallowing, hoarseness, a feeling that something is stuck in the throat, or a lump in the neck. These symptoms can also occur with non-cancer conditions, so a doctor’s assessment is important if they persist.^1,2,7

Is throat cancer contagious?

No. Throat cancer is not contagious and cannot spread from one person to another through coughing, kissing, sharing food, or close contact. It develops from changes in a person’s own cells. HPV infection can spread between people, and some HPV infections can increase the risk of oropharyngeal cancer, but the cancer itself does not spread from person to person^4,15.

Can vaping cause throat cancer?

Vaping exposes the throat to potentially harmful substances that may cause cellular damage. However, it is still unclear whether vaping directly causes throat cancer, and more long-term research is needed¹⁶.

Can you get throat cancer from HPV?

Yes, certain high-risk types of HPV, especially HPV-16, can increase the risk of developing throat cancer, particularly cancer of the oropharynx⁴.

Can acid reflux cause throat cancer?

Acid reflux does not mean that a person will develop throat cancer. Some research has linked long-term gastro-oesophageal reflux disease with a higher risk of laryngeal cancer, but more research is needed to understand this relationship¹⁷.

Can oral sex cause throat cancer?

Oral sex itself does not directly cause throat cancer. However, it can transmit HPV, and some high-risk HPV infections can increase the risk of oropharyngeal cancer^4,18.

How to detect throat cancer?

Doctors usually detect throat cancer through a physical examination, imaging tests and a biopsy, where a small tissue sample is checked for cancer cells^11,12.
