You’ve probably heard of this disclaimer on multiple occasions – ‘smoking is injurious to health’. What you may not immediately realise is the extent of the damage smoking can cause to your health and, most directly, your lungs.
Smoking is known to be the leading cause of preventable diseases and deaths globally. Nearly all forms of lung cancer, the top cause of cancer death in both men and women, can be attributed to smoking. Tobacco and tobacco-related products can damage the lungs’ ability to supply oxygen to the body. Other substances commonly found in cigarette smoke can cause permanent lung damage, even in small amounts.
A single puff of cigarette smoke contains upwards of 7,000 chemicals. Tobacco smoke contains over 70 known cancer-causing chemicals2. When you breathe these in, these toxins go deep into your lungs and can cause swelling, resulting in a host of other respiratory diseases.
Both tobacco and chemical substances found in cigarettes can change the cellular structure of the lungs. They can cause the elastic walls within the airways to break down – resulting in less functioning surface area in the lungs. Cigarettes can damage lung tissue, preventing them from functioning correctly. This can increase the risk of diseases caused by smoking, such as chronic bronchitis, emphysema, respiratory diseases, asthma and COPD (Chronic Obstructive Pulmonary Disease)1.
Nicotine in tobacco can also damage the ability of the respiratory system to filter out dust and dirt. This can lead to toxic substances passing through, resulting in lung congestion and the ‘smoker’s cough’.

A person who smokes throughout life is at high risk of developing a range of potentially fatal diseases owing to impaired lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus build-up. They are also prone to weakening the lungs’ clearance system, leading to the accumulation of toxic substances and causing lung irritation and damage. Further, they are also at an increased risk of lung infection, chronic bronchitis and heightened risk of asthma, along with permanent damage to air sacs3.
In the longer term, smoking is known to induce heart disease and stroke, in certain cases, it can cause ulcers of the digestive system and put smokers at increased risk of type 2 diabetes.
Most smokers are also likely to develop emphysema. The number of cigarettes you smoke and other lifestyle factors may impact the extent of the damage. If you’re diagnosed with either of these respiratory diseases – emphysema or chronic bronchitis, you run the risk of being diagnosed with chronic obstructive pulmonary disease (COPD).

Smoking can affect a person’s health in other ways, too, harming almost every organ in the body. In most cases, it can result in a compromised immune system function, making you susceptible to many other illnesses. It can also lead to lower bone density (brittle bones), which increases the risk of broken bones and fractures. Smoking also leaves you at a higher risk of rheumatoid arthritis, heart disease and stroke, along with an increased risk for cataracts (clouding of the eye lenses).
Apart from respiratory diseases, other visible disorders include an increased risk of oral cancers, gum disease and tooth loss, premature ageing of the skin, bad breath and stained teeth and an increased risk for age-related macular degeneration, which can lead to blindness. Moreover, even your wounds may take longer to heal!

It’s never too late to quit smoking. Within days of quitting smoking, lungs begin to repair themselves. In fact, just 12 hours after you quit, the amount of carbon monoxide in your blood drops to a much healthier level. More oxygen flows to your vital organs and you will be able to breathe better. In about 10 to 15 years, your risk of developing lung cancer reduces and may even become the same as a non-smoker4.

31st May is known as the ”World No Tobacco Day” and for a good reason too1. Did you know that more than 10 million die each year in India due to tobacco? India is home to 12% of the world’s smokers, according to the World Health Organization (WHO). You have heard numerous people tell you that smoking affects your lungs. You have seen the gross pictures on cigarette packs but smoked anyway. But did you know that smoking affects your brain too?
Nicotine works like the various neurotransmitters that are already there in our brain. It activates dopamine signals that result in a pleasant sensation in your brain. With the passing of time and more smoking, the brain reduces acetylcholine receptors to compensate for the increased signalling activity. As a result, nicotine tolerance is created in the brain2.
The brain ends up needing more nicotine. As nicotine mimics the work of dopamine that provides the feel-good factor, your brain starts associating smoking (nicotine use) with feeling good. The nicotine in cigarettes changes your brain and makes you suffer from withdrawal symptoms when you try to quit. You start feeling irritable, anxious, and your body has a strong craving for nicotine. As a result of these symptoms, most people reach for another cigarette, and then another and are unable to quit.
Brain size and volume is associated with higher intelligence and better cognitive functioning. The average brain volume in adult males is 1260 cubic cm and 1130 cubic cm in adult females. According to a 2017 study2, the longer you smoke, the more your brain loses volume with vital tissues shrivelling up.
Smoking affects the subcortical brain regions. The subcortical areas of the brain are associated with pleasure, hormone production, emotion, and memory. Smokers thus develop age-related loss of brain volume that leads to an increased risk of dementia and is one of the ways how smoking harms the brain.
Dementia is a syndrome that is characterized by deterioration in thinking, memory, behaviour, and the ability to perform everyday activities. It is said to affect older people mainly, but it is not a normal part of ageing. Since smoking affects the subcortical regions of the brain that are associated with memory, it puts smokers at a higher risk of dementia.
In 2015, a research team reviewed 37 studies that compared smokers and non-smokers and found that smokers were 30 % more likely to be affected by dementia. Quitting smoking can decrease the risk of dementia in the person4.
Cigarette smoking has been associated with dementia and dementia-related brain changes, notably gray matter (GM) volume atrophy. These associations are thought to reflect the co-morbidity of smoking and vascular, respiratory, and substance use/psychological conditions.
Dr. M.G. Kartheeka, MBBS, MD(Pediatrics)
One of the smoking effects on brain is cognitive decline, which usually happens as people get older. But in smokers, it starts much earlier. Signs and symptoms of cognitive decline include:
In 2012, the cognitive data of about 7,000 men and women were studied for 12 years. The researchers found that smokers experienced a much more rapid cognitive decline than non-smokers. Middle-aged male smokers were found to be more at risk than female smokers4.
If you smoke say, 20 cigarettes a day, you are 6 times more likely to have a stroke than a non-smoker. Tobacco contains over 7,000 harmful chemicals, including formaldehyde, cyanide, arsenic, and carbon monoxide. These toxic chemicals get transferred from the lungs to the blood. They make platelets more likely to stick together. Platelets help in clotting the blood in case of blood loss, but if the platelets stick together, it increases the chance of clot-forming5.
Smokers are at a higher risk of developing atherosclerosis where arteries become hardened and narrow. It restricts smooth blood flow making the formation of blood clots more likely. If a clot forms in an artery leading to the brain, it can block the blood supply to a part of the brain resulting in a stroke. This is known as ischaemic stroke. Smoking is said to double the risk of having an ischaemic stroke. If a person quits smoking, within 5 years, his/her risk of stroke will start decreasing to that of a non-smoker.
Smoking releases a severe amount of toxicity in our bodies. There are about 60 known cancer-causing substances in tobacco6. The chemicals that make up a cigarette are:
Smoking also causes a temporary spike in blood pressure, which can weaken the arterial walls and make them more prone to form an aneurysm and rupture. The harmful chemicals in a cigarette are also implicated in the causation of brain cancer.
Dr. Ashish Bajaj, M.B.B.S., M.D. in Clinical Pharmacology and Toxicology
Smoking affects the brain and hence, mental health. Sometimes, bad mental health makes people take up smoking and worsen their conditions. Other times, it is the other way around7.
The nicotine from cigarettes alters the brain. It makes the brain connect ‘feeling good’ to smoking. Quitting smoking becomes tough after some time because smokers start suffering from withdrawal symptoms. They then find solace in smoking and fall prey to the dangerous cycle and become addicted.
How many times have you heard somebody say, ‘I’m feeling stressed out, I need to smoke right now’ or ‘Smoking makes me feel relaxed’7?
Stress is very common and can cause symptoms like headaches, irritability, anxiety, and/or breathlessness at times. Smoking increases the occurrence of these symptoms. Smokers start feeling the symptoms if they do not smoke for a long time and associate smoking with being a reliever of stress.
Nicotine mimics the work of dopamine, prompting the brain to switch off its mechanism that makes and secretes dopamine. In the long term, the supply of dopamine decreases in the brain and inspires people to smoke more. There is a complex relationship between depression and smoking. Smokers with depression have more trouble quitting as withdrawal symptoms become more severe in them7.
Research has shown smoking increases tension and anxiety. The relaxed feeling that smokers talk about after a quick smoke fades away just as quickly. It is hugely short-lived and only adds more jitteriness in the smoker, making him/her reach for more7.
It has been reported that people who suffer from a serious mental disorder known as Schizophrenia tend to be heavy smokers. Some people suffering from this disorder have claimed that smoking helps them to numb the debilitating symptoms of schizophrenia and also to mitigate the side effects experienced from the medication for the same. Ironically, recent research has found that excessive smoking may very well be one of the causes for the onset of schizophrenia. However, since there is more research required to fully confirm this, it has not yet received mainstream acceptance. Nevertheless, it is best to avoid smoking to reduce the risk of developing such mental disorders8.
Yes, e-cigarettes have negative effects on the brain too. National Institute on Drug Abuse has reported that the nicotine in e-cigarettes goes about making similar harmful changes in the brain. E-cigarette vapour contains harmful chemicals too hence it is not a way out.
If all this information on how smoking affects the brain has you worried, you can always try quitting. Most addictions are hard to overcome. But since smoking has been around for a while there are well-established methods to try out. Keep in mind, since everyone is different not all approaches will work the same for you. Some may be more effective than others, do what works best for you9.
Absolutely! Within 20 minutes of quitting smoking, your heart rate will slow down. Within 12 hours, levels of carbon monoxide in your blood will start decreasing. Within 3 months, lung functions and blood circulation will start getting better. Within a year of quitting, your risk of having a heart attack will start decreasing by a whopping 50 %. Within 5 to 15 years, your risk of suffering a stroke will reduce to that of a non-smoker.

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.
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?
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.
Ear discharge causes are mainly pointing towards any underlying infections, past injuries or procedures done in the ear.
Ear discharge symptoms can vary based on the causes of discharge and include:
| 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. |
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.
Ear discharge treatment can vary based on the underlying cause, and it can be8:
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 that can help for ear discharge depend on the cause and symptoms of the discharge8:
Untreated ear infections along with the discharge can lead to complications, including2:
The following general preventive measures can be taken to avoid ear discharge:
Consultation with a doctor is recommended in the following instances7:
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.
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.

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.
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.
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.
Ear discharge is not contagious. Discharges associated with external ear infection or middle ear infection don’t spread from person to person3,10.
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.
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.
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.

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

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.
Note: Treatment may also include supportive care to help with swallowing, nutrition, speech, pain and other treatment-related effects.
Throat cancer cannot always be prevented, but reducing known risks can lower the chance of developing it. The following steps may help reduce risk:
Note: These measures may lower risk, but they cannot guarantee complete prevention. A doctor or dentist should evaluate persistent, unusual, or worsening throat symptoms.
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 phlegm1,7. These symptoms can have many causes and do not necessarily mean cancer but getting them checked can help identify the problem early.

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.
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.
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 stage4,5.
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
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 person4,15.
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.
Yes, certain high-risk types of HPV, especially HPV-16, can increase the risk of developing throat cancer, particularly cancer of the oropharynx4.
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.

Cancer is considered one of the major health concerns worldwide. Cancer can affect any organ or tissue, and based on these, the causes, symptoms, and treatments can vary from case to case. Though not all cancers are preventable, adopting some healthy lifestyle habits and limiting the known risk factors can help in reducing the risk of developing certain types of cancers. This blog helps you understand what cancer is, its risk factors, how to prevent cancer, its diagnosis, treatment and when to seek medical advice to avoid unnecessary concerns and make informed decisions about one’s health.
Cancer is a disease in which certain cells in the body grow and multiply uncontrollably. In the human body, a natural process takes place as new cells are formed along with the removal of old, damaged cells. Normally, this process is controlled by many factors and in cancer, this normal mechanism is disturbed, which leads to the increased growth and multiplication of damaged cells.
Cancer cells behave differently from normal cells with regard to the processes involved in cell growth, division, repair, death and response to body’s immune system1.
Did You Know?
Cancers are caused by changes (mutations) in genetic materials which control the normal cell division process1. Several factors can control this, and avoiding these can help in the prevention of cancer occurrence. However, not every cancer is preventable, as some factors are non-modifiable, such as age and family history. However, 30%-50% of deaths due to cancer can be prevented by avoiding the risk factors and adopting evidence-based measures3.
Factors which might put a person at an increased chance for being affected by cancer are termed risk factors. These include:
Increasing age is considered one of the common risk factors of cancer. However, the age at which cancer may develop can vary based on the type of cancer. Cancers affecting the breast, colon, lung, and prostate usually occur around 63-72 years of age, while cancers like leukaemia are more common in children4.
Certain cancers can run in families through the passing down of genetic changes, which might increase the risk of cancer from their parents. This does not mean that cancer itself is passed down from the parents; rather, the changes in genes that put the person at an increased risk can be passed5.
Alcohol intake is linked with mouth, throat, liver and breast cancers. While, there is no completely risk-free level of alcohol consumption with to respect to cancer, the risk can be higher for those people who drink alcohol along with the use of tobacco6.
Certain infectious agents can increase the risk for developing cancer. Some viruses act by disturbing normal cell proliferation, and some infections might lead to weaker immunity and thereby to cancer. Viruses such as Epstein-Barr Virus (EBV), Hepatitis B and C viruses (HBV and HCV), Human immunodeficiency virus (HIV), human papillomavirus (HPV), human T-cell leukaemia virus (HTLV-1) and a bacterium named Helicobacter pylori (H.pylori) might increase the risk of certain cancers. Certain parasitic flatworms can also be involved in cancer development7.
High-energy radiation such as X-rays and gamma rays is most involved in the incidence of certain cancers. Some of the diagnostic procedures, including X-rays, computed tomography (CT), or positron emission tomography (PET) scans, might produce small changes in cells, though the risk for developing cancers is limited. Low-energy radiation such as that from cell phones and visible light has not proved to induce cancers in humans8. Radiotherapy on the other hand, intentionally uses high doses of ionizing radiation and can cause DNA damage to normal tissues; however, its benefits usually outweigh the long-term secondary-cancer risk when appropriately indicated.
Inflammation that lasts for a prolonged period might be caused by some infections, certain conditions such as obesity and abnormal immune reactions. The changes induced by these can also be reflected in DNA abnormalities and thereby lead to cancer. Chronic inflammatory diseases such as ulcerative colitis and Crohn’s disease can increase the risk of developing colon cancer9.
Hormones such as oestrogen are found to be associated with an increased risk for developing cancers, though they possess some normal functions in the human body. Evidence highlights the risk of breast cancer in women is more linked with the production of hormones such as oestrogen and progesterone from their ovaries. Long exposure to these hormones from early menstruation (menarche) and late permanent stoppage of monthly periods (menopause), delayed pregnancies and no history of any childbirth can be considered risk factors10.
In healthy individuals, under normal physiologic conditions, certain types of cancer cells can be detected by the body’s immune system, which tries to eliminate these abnormal cells. But, in people who have undergone organ transplants, certain immunosuppressive medicines are given to avoid rejection by the body. When these immunosuppressive drugs are taken, or under in case of certain infections like HIV, which weakens the immune system, these cells fail to detect the cancer cells. In HIV affected people, most cancers caused by certain viral infections are seen, although some non-infectious related cancers such as lung cancers can also be seen11.
Obese people are more prone to get affected with cancers of the breast, colon, rectum, kidney cancer, pancreas and gallbladder, although some other factors can also contribute to the development12.
Ultraviolet radiation (UVA and UVB) in sunlight is considered an inducing factor of cancer development. These radiations can accelerate skin ageing and cancers. People of any skin tone can develop skin cancer; however, people with a light skin tone are more prone to develop it13.
Use of tobacco is considered one of the common causes of death due to cancers. People who use tobacco or who are constantly exposed to environmental tobacco smoke might develop cancer due to the presence of certain chemicals in it. They are more prone to develop lung, mouth, throat, kidney, liver, stomach, colon and rectum cancers. Smokeless tobacco is involved in inducing mouth cancers, and it increases the risk of oesophageal or pancreatic cancers14.
Certain chemicals in the environment, including the ones in the air, water, food or in the materials we use, might cause some DNA damage. Some of these can be avoided, such as tobacco smoke, radiation, and UV rays. Other substances that might also cause cancer are arsenic, cadmium, radon, untreated mineral oils, etc. However, chances of developing cancers depend on many other factors, including the exposure duration and amount15.
These risk factors can be modifiable, that is those which can be altered by adopting some healthy lifestyle measures, or nonmodifiable, those which cannot be controlled. While nothing can be done about the nonmodifiable factors, reducing exposure or avoiding the modifiable risk factors might be helpful in cancer prevention.
Limiting or avoiding the modifiable risk factors along with adopting the evidence-based preventive measures are beneficial in preventing the deaths associated with certain cancers. The complications associated with these cancers can also be reduced by timely detection and early initiation of management strategies:
Avoiding all forms of tobacco, including smoking and smokeless tobacco is advised16.
Achieving a healthy weight can help in preventing obesity associated cancers16.
A diet including a lot of fruits and vegetables is recommended16.
Intake of alcohol can be seen linked with many cancers, such as mouth, throat, liver and breast and avoiding it can help in preventing the associated cancers6.
Regular exercise can help in prevention16. For adults, aiming for at least 150 minutes of moderate activity or at least 75 minutes of vigorous-intensity activity weekly is recommended17.

Vaccinations against hepatitis B virus (HBV) and human papillomavirus (HPV) can be beneficial in preventing the cancers caused by them3.
Limiting sun exposure, particularly between mid-morning and late afternoon, can be beneficial in preventing UV-induced cancers. Wearing a hat that covers the face, neck and ears, wearing sunglasses when under sunlight, and wearing dresses with long sleeves and pants are preferred. Application of sunscreen with sun protection factor (SPF) of at least 30 and 30 minutes before going outside is recommended. Reapplication every two hours or after swimming or sweating can provide an added advantage13.
Reducing unnecessary exposure to radiation from occupational sites or following safe medical use of radiation in diagnosis and management can help in the prevention of certain cancers8.
No single test is available to detect cancer. Your doctor can diagnose cancer by sequential diagnostic methods. However, these tests can vary from person to person based on the type of cancer and their symptoms18:
Note: Specific screening tests for selected cancers also need to be considered such as mammography for breast cancer, HPV testing for cervical cancer screening, sputum cytology for lung cancer, colonoscopy for colorectal screening etc.
Screening and early detection can reduce cancer mortality for selected cancers.
Many types of cancer treatments are available, and the type of treatment for one person may vary from another based on the type of cancer and how advanced it is. Most people will have a combination of treatments, though some have only one. These can include19:
Certain common myths about cancer might lead to unnecessary concerns and related anxieties, which can lead to other complications. These myths can sometimes delay evidence-based preventive measures, timely identification and management strategies20:

If you notice any unusual symptoms such as new lumps, persistent fatigue or fever, unexplained weight loss or any changes that are not normal or if you are worried that these could be signs of cancer, you need to consult a doctor.
Cancer is considered one of the major health burdens worldwide. Cancer is considered the abnormal growth and multiplication of certain cells following certain mutations in associated genes. Cancer can affect any organ, and there can be several cancers which vary in their causes, symptoms, preventive measures, and treatment modalities. Having proper awareness about cancer can avoid unnecessary concerns and can help in timely medical evaluation and taking appropriate management measures.

Though all cancers are not completely preventable or treatable, certain types of cancers can be prevented by adopting some healthy lifestyle measures such as limiting alcohol and tobacco, being physically active, avoiding UV radiation from sunlight and maintaining a healthy weight21. If persistent anxiety about cancer is affecting daily life, consulting a doctor is recommended.
Antioxidants are beneficial in preventing the damage caused by free radicals associated with cancer. However, limited evidence is available regarding the role of antioxidants in preventing the development of cancer. Some studies have shown an increased risk for cancer development linked with antioxidant usage22.
Regular exercise can help alter some risk factors associated with cancer occurrence. Being physically active can help maintaining a healthy body weight and lower inflammation, which have been linked to cancer development3.
Certain vaccines against hepatitis B and human papillomavirus (HPV) might help prevent the cancers that are caused by these viruses3. However, these vaccines might not prevent all cancers.
Autophagy is a natural process that occur in cells which involve transportation of cell components to lysosomes for their digestion. Autophagy is involved in several processes associated with cancer. It can limit cell death and inflammation and the spreading of tumour cells to other sites in the body. In contrast, it can also promote the invasion of tumour cells to new sites in its later stages. So, the role of autophagy as a lethal or protective factors are needed to be explored further23.

Do you often feel unusually tired, unwell, or uncomfortable in your upper abdomen without knowing why? Many women may link these changes to stress or hormonal fluctuations. However, they can also be signs of fatty liver disease, especially when risk factors such as weight gain, diabetes, high cholesterol, polyendocrine metabolic ovarian syndrome (PMOS), or menopause are present1. This blog explains the common symptoms of fatty liver in women, why they may happen, and when to speak with a doctor.
Fatty liver disease means there is excess accumulation of fat within liver cells, exceeding 5%–10% of total liver weight, a condition called steatosis2,3. The liver produces bile, which helps digest fats and supports the absorption of fat-soluble substances, stores energy, and metabolises waste products from the body2. Excess fat accumulation can cause inflammation of the liver and may lead to swelling of the liver cells due to fat deposition, scarring (also known as liver fibrosis), or long-term liver damage in the form of cirrhosis if it is not managed3.
Fatty liver disease is renamed steatotic liver disease. The common forms are:
Fatty liver can affect both women and men. In women, the risk may increase with hormonal changes after menopause and with conditions such as PMOS, which can be linked to insulin resistance and weight gain. If fatty liver is not managed, it can progress in some people to liver inflammation, injury to the liver cells, or liver failure5.
Fatty liver disease often has no clear symptoms, and hence it is important to screen for MASLD6. When symptoms do occur, they may be mild and easy to confuse with other health issues. Symptoms may very rarely include:
Symptoms that may suggest more serious liver damage/end stage liver disease, requiring urgent medical care, include:
Several factors can increase a woman’s risk of developing fatty liver disease. These include:
Doctors diagnose fatty liver disease based on a person’s medical history, symptoms, and other associated risk factors such as concomitant alcohol use or chronic viral hepatitis, physical examination, and test results. They may recommend:
Treatment mainly focuses on healthy lifestyle changes and managing related health conditions. The goal is to reduce fat in the liver, lower the chance of scarring, and improve overall health. It is recommended to start the following:
If you are overweight, gradual and steady weight loss can reduce liver fat. Even modest weight loss (target of 0.7-1 kg/ week while maintaining a sustainable diet) may help, and larger sustained weight loss may improve liver swelling and scarring in some people5,9.
Inherently, a staple Indian diet lacks protein; hence, incorporating adequate protein helps counteract the quantity of fat and carbohydrate intake, in turn leading to a balanced meal. A balanced diet with vegetables, fruits, whole grains, pulses or lean proteins, and healthy fats can support liver health. It is helpful to abstain from alcohol- there is no “safe limit” of alcohol it is not recommended in small quantities, sugary drinks, sweets, fried foods, processed foods, and foods high in saturated fat. Quitting smoking is also important for overall health9.
Activities such as brisk walking, cycling, swimming, along with strength exercises can help improve blood sugar control, blood pressure, cholesterol levels, and weight. Many guidelines suggest aiming for about 150 minutes of moderate activity or 75 minutes of intense physical activity each week, if your doctor says it is safe for you9.
Managing conditions such as type 2 diabetes, high cholesterol, high blood pressure, and PMOS can help reduce the risk of fatty liver progression5,9.
Follow-up tests may be recommended to track liver health and check for any signs of progression.
Speak with a doctor if you have:
Fatty liver disease in women often has no symptoms at first, but it can become serious if it is not managed. Knowing your risk factors, maintaining a healthy weight, eating a balanced diet, staying active, and abstaining from alcohol can help protect your liver. Regular check-ups are especially important for women with diabetes, PCOS, obesity, high blood pressure, or high cholesterol.

Yes, fatty liver can be asymptomatic (without any specific symptoms) in both men and women during the early stages. However, when symptoms occur, women may experience fatigue, a general feeling of being unwell, or abdominal discomfort1,11.
Yes, PMOS can increase the risk of fatty liver, as it is associated with insulin resistance, weight gain, hormonal changes, etc5.
Yes, menopause can increase the risk of fatty liver disease, as the decline in oestrogen levels during this phase is associated with increased fat accumulation in the liver5.
Women with fatty liver should limit foods high in sugar, unhealthy fats, and refined carbohydrates, as they can increase fat buildup in the liver. Examples include sugary drinks, sweets, processed foods, and fried foods9.
Fatty liver symptoms in females are generally similar to those in males, but many people may not experience symptoms in the early stages11. However, women may have certain risk factors, such as menopause and PMOS, that can increase their likelihood of developing fatty liver disease5.
Fatty liver disease may cause bloating or a feeling of fullness in some people. However, weight gain is generally a risk factor for fatty liver, rather than a direct symptom of the condition5.

Hypertension means an increase in blood pressure, i.e., greater than 140/90 mmHg. This happens when the blood pushes against the arteries at high pressure. People with hypertension may not feel any symptoms. But very high blood pressure can cause headaches, chest pain, and blurred vision. Severe hypertension can cause major complications like heart disease, stroke, etc1.
Appropriate treatment is important to prevent complications of hypertension, and the condition usually requires long-term treatment2. Since high blood pressure requires long-term treatment, generic high blood pressure medicines can help reduce the treatment cost and encourage patients to take medicines consistently, leading to better blood pressure control3.
A generic drug is an approved form of the brand drug that mimics the branded drug in its safety, effectiveness, dosage and route of administration4. Many people with high blood pressure prefer switching from branded medicines to generics, which provide the same clinical effect at a lower cost. As hypertension is a long-term disease condition, affordability plays an important role in helping patients take their medications regularly. Doctors recommend generic medicines when an approved generic medicine is available in the market.
Reasons to switch to generic hypertension drugs can be as follows5:
There are several types of generic high blood pressure medicines available. Each belongs to a different drug class and lowers blood pressure in a different way. Your doctor will choose the most suitable medicine based on your blood pressure, age, overall health, and other medical conditions. As per the regulatory authorities, these medicines are categorized as follows6,7:
How do they work?
These medicines reduce the production of a hormone called angiotensin II, which normally causes constriction of blood vessels.
How do they work?
Instead of reducing the production of angiotensin II, ARBs prevent it from attaching to its receptors. This keeps blood vessels relaxed and helps lower blood pressure.
How do they work?
These medicines reduce the amount of calcium entering the muscle cells of the heart and blood vessels. As a result, blood vessels relax, making it easier for blood to circulate.
How do they work?
Diuretics help the kidneys remove extra salt and water from the body through urine. This reduces the amount of fluid in the blood vessels, lowering blood pressure.
How do they work?
Reduces the heart rate and the force of heart contraction. This helps reduce blood pressure.
Generic medicines used to treat high blood pressure are considered safe, effective, and reliable once they have been approved by regulatory authorities. Before a generic medicine becomes available to patients, it undergoes a thorough scientific evaluation to confirm that it performs in the same way as the original brand-name medicine. This means it must contain the same active ingredient, be available in the same strength and dosage form (such as a tablet or capsule) and be administered in the same way. It must also show that the body absorbs and uses the medicine similarly to the branded product, ensuring that patients receive the same blood pressure-lowering effect.
In addition to proving effectiveness, manufacturers must comply with strict quality standards during production. Every batch of an approved generic medicine is expected to meet the same manufacturing, purity, and quality requirements as the corresponding brand-name medicine. Therefore, patients can use approved generic blood pressure medicines with confidence, knowing they provide effective blood pressure control at a more affordable cost4,5.
All blood pressure medicines have side effects. Mild side effects may improve over time. Some of the common side effects of blood pressure medicines include8:
Contact your healthcare provider as soon as you observe any side effects. Changes in the dose of the medicines can help reduce the side effects. Do not stop or skip any medicines on your own.
The following are a few tips to be considered while taking generic high blood pressure medicines9:
Although hypertension has no symptoms, regular blood pressure check-ups are important. Regular monitoring by a healthcare professional is particularly needed if you have factors that increase your risk of having hypertension, like a sedentary lifestyle, an unhealthy diet typically high in sodium, excessive body weight, smoking or alcohol habit, or a family history.
Immediate medical attention may be needed in the following situations:

Generic high blood pressure medicines play an important role in the treatment of hypertension. They provide the same therapeutic benefits at a reduced cost as compared to branded medicines. This helps patients to take the medicines regularly, improving medication adherence. Patients should take medicines as prescribed, not stop/change medicine on their own, monitor their blood pressure regularly and adapt lifestyle changes along with medication for optimal management of hypertension. Keeping a check of warning signs is important to avoid any complications.
Also Read: Are Generic Medicines Effective for the Elderly?
Yes. Generic blood pressure medicines are as effective as brand-name medicines. They have the same active pharmaceutical ingredient, strength, dosage form, etc. Regulatory authorities ensure that generic medicines are safe and effective as brand-name medicines3,5.
The commonly prescribed generic medicines for blood pressure are ACE Inhibitors, Angiotensin II Receptor Blockers, Calcium Channel Blockers or Diuretics6. Your doctor decides which is the best suited for you.
No. Do not stop or skip your blood pressure medicine without consulting your doctor. A normal blood pressure reading often means that your medicine is working effectively. Stopping treatment suddenly can cause your blood pressure to rise again, increasing the risk of heart attack, stroke, kidney disease, and other complications8.
Yes. In most cases, you can safely switch from a brand-name medicine to its approved generic equivalent after discussing it with your doctor. Generic medicines are designed to provide the same clinical effect as brand-name medicines while being more affordable. However, always consult your doctor before making any changes to your medication to ensure the generic medicine is appropriate for your individual health needs11.

Have you ever noticed changes in your bowel habits, blood in your stool, unexplained abdominal discomfort, or ongoing tiredness and wondered if it could be bowel cancer? These symptoms can have many causes and may occur with a number of benign (non-cancerous) diseases, but it is important not to ignore them when they persist1. This article explains everything you should know about bowel cancer in a simple and easy-to-understand way.
Large bowel cancer, also called colorectal cancer, is a type of cancer that develops in the large intestine1. The large intestine includes parts like the colon and rectum, which help the body process waste before it leaves the body2. Bowel cancer usually begins when abnormal cells in the inner lining of the bowel (intestine) grow and multiply in an uncontrolled manner. Over time, these cells can form a growth called a tumour and may spread to other parts of the body if not treated1.
Did You Know?
The different types of bowel or colorectal cancers include:
The stage of bowel cancer describes how far the cancer has grown or spread. Bowel cancer is generally divided into Stages 0 to IV:
Note: The exact stage is determined using test results, including examination of the tumour and lymph nodes. The stage may be further divided into Stages 2, 3 and 4 and into sub-stages based on the extent of spread.
Bowel cancer symptoms in early stages are minimal. However, symptoms can be more noticeable in the later stages and include:
Bowel cancer does not usually have one single cause. It develops when changes occur in the DNA of bowel cells, causing them to grow and divide abnormally. These changes can build up over time and may eventually lead to cancer. Important causes include:
A risk factor is something that increases the likelihood of a disease. The risk factors for bowel cancer include:
Note: Although these factors increase the risk of developing the disease, having one or more of them does not necessarily mean that a person will develop bowel cancer or that people with none of these risk factors may not develop bowel cancer. Bowel cancer may also occur in people who have no known risk factors.
Bowel cancer is diagnosed using a combination of medical history, physical examination and tests. The doctor may use the following strategies to diagnose a bowel cancer:
Bowel cancer treatment depends on factors such as the location and stage of the cancer, its size and the person’s overall health. Doctors may use one treatment or combine several approaches.
Surgery is an important treatment for many colorectal cancers, and it may be performed during different stages of the cancer as needed. The surgeon removes the cancer along with an appropriate area of surrounding tissue. Nearby lymph nodes will also be removed and examined. The healthy ends of the bowel are then joined back together.
Examples: Hemicolectomy or total colectomy. In case of polyps (which may be precancerous) polypectomy or endoscopic submucosal dissection can be performed for complete & safe removal.
This treatment uses medicines that destroy cancer cells or stop them from multiplying. It may be given in different forms, such as an injection or tablets to be taken orally. Chemotherapy may be done after surgery to reduce the risk of cancer returning, before surgery in selected cases (to shrink the tumour), or for advanced disease.
Examples of chemotherapy medicines: Leucovorin, capecitabine, and oxaliplatin.
This method uses high-energy radiation to destroy cancer cells. Radiation therapy can be external (radiation is given using a machine, outside the body, to the area where cancer is present) or internal (sending radioactive waves directly into the cancer cells or near them). It may be given before or after surgery depending on the need.
This treatment uses specific medicines that act on specific cancer cells. The doctor may choose the type of medicine based on the biomarker test. It may be given alone or with chemotherapy.
Examples of targeted therapy medicines: Encorafenib, bevacizumab, and panitumumab.
This method uses medicines that help the immune system recognise and attack cancer cells. The doctor may choose the type of medicine based on the biomarker test. It may be suitable for certain colon cancers with specific characteristics.
Examples of immunotherapy agents: Ipilimumab, nivolumab, and pembrolizumab12.
Note: When colorectal cancer has spread to the distant organs, treatment may include a combination of chemotherapy, targeted therapy, immunotherapy and surgery or other local treatments in selected patients. The treatment plan is individualised based on the area of spread of cancer.
Although not all bowel cancers can be prevented, certain lifestyle changes may help reduce its risk. These include:
Note: These lifestyle measures may help lower the risk of bowel cancer, but they cannot guarantee that cancer will be prevented. Some people may develop bowel cancer even after following a healthy lifestyle.
It is important to seek medical advice if you have any of the following:
You may require urgent medical attention if you have symptoms like heavy bleeding through the rectum, bloody diarrhoea, and severe abdominal pain1,8.

Understanding the meaning of bowel cancer can help you recognise the disease and its warning signs early. Regular screening, a healthy lifestyle and timely medical advice can lower the risk and support early detection. If you notice ongoing changes in your bowel habits or other unusual symptoms, consult a doctor without delay.
Survival depends on how early the cancer is found. When detected before its spread, the 5-year survival rate can be around 91%13.
Yes, bowel cancer can be cured, especially when it is found and treated early. The chances of cure depend on the cancer’s stage, type and how well it responds to treatment3.
Bowel cancer can run in families, but not all bowel cancer is inherited. Having a close family member with bowel cancer may increase your risk1,3.
Increased gas or flatulence alone is usually not a sign of bowel cancer and can happen due to diet or other digestive problems. However, if it is persistent and occurs with blood in the stool or lasting changes in bowel habits, consult a doctor14.
Constipation does not always mean bowel cancer. However, constipation that is new, persistent or occurring with blood in the stool, weight loss or ongoing abdominal pain should be checked by a doctor1,8.
Yes, bowel cancer and colorectal cancer generally mean the same thing; cancer that develops in the colon or rectum, which are parts of the large intestine1.
Regular or heavy alcohol use can increase the risk of bowel cancer. The risk tends to increase further as alcohol intake increases1,10.
Yes, smoking can increase the risk of bowel cancer. Risk increases with the number of cigarettes smoked1,10.
Weight gain is not a typical sign of bowel cancer. Unexplained weight loss is more commonly associated with the disease. However, people with increased weight have a higher chance of getting bowel cancer1,8.
Back pain is not usually an early sign of bowel cancer. However, some people with bowel cancer may experience back pain if there is spread to the vertebrae/spine15.
Bowel cancer can sometimes cause pain or discomfort around the anus, particularly when the cancer affects the anus. However, conditions such as piles or anal fissures are more common causes of pain in the anus16.
Men and women may have many of the same bowel cancer symptoms, such as changes in bowel movements, blood in the stool, and stomach or abdominal pain. Women are more likely to develop cancer on the right side of the bowel, where symptoms may be less common. Signs such as anaemia and ongoing abdominal discomfort may occur, so the condition can sometimes go unnoticed until it becomes more advanced17.

Persistent indigestion, stomach discomfort, or unintentional weight loss can be a cause for concern, especially if the symptoms persist or recur. In many cases, these symptoms may be caused by common digestive problems1. However, when such symptoms continue or become worse, they should not be ignored, as they can sometimes be linked to stomach cancer. In this blog, we will discuss stomach cancer, its stages, symptoms, causes, treatment options, and when to seek medical attention.
The stomach is a muscular organ in the upper abdomen that helps break food down during digestion. Stomach cancer, also known as gastric cancer, is a type of cancer that begins when cells in the stomach start growing abnormally and uncontrollably. The most common type of stomach cancer is adenocarcinoma, which develops from the mucus-forming cells in the innermost lining of the stomach2,3. Over time, abnormal cells from this lining can grow deeper into the stomach wall and may eventually spread to other organs2.
In the early stages, stomach cancer may have mild to no symptoms, making it difficult to notice1. This is why ongoing or unusual digestive symptoms should be evaluated by a doctor rather than being treated as simple indigestion that occurs repeatedly4.
Stomach cancer symptoms may change as the disease progresses. The table below compares symptoms that may occur in the early and advanced stages of stomach cancer.
| Early Symptoms | Advanced Symptoms |
| Unexplained indigestion | Vomiting (often with blood) |
| Nausea (mild) | Blood in the stool (rarely) |
| Stomach discomfort | Unexplained weight loss |
| Lack of appetite | Difficulty swallowing |
| Heartburn | Abdominal pain or bloating |
| Yellowing of skin and eyes (jaundice) | |
| Fluid build-up in the abdomen (ascites) | |
| Anaemia accompanied by easy fatigability/generalised weakness |
Stomach cancer does not usually have a single cause. It develops when changes in the cells of the stomach cause them to grow and multiply abnormally. Factors that may increase the chance of these changes include:
Certain factors can make a person more likely to develop stomach cancer. These include:
Note: Having any of these risk factors does not mean that a person will develop stomach cancer. These factors only indicate that the likelihood of stomach cancer may be higher. If you have concerns about your risk or experience persistent digestive symptoms, speak with your doctor for appropriate advice and evaluation.
There are different types of stomach cancer based on the type of cells they originate in.
Note: There are certain other types of cancers, such as squamous cell carcinoma, small cell carcinoma, and leiomyosarcoma, that can develop in the stomach. However, these forms are uncommon.
Stomach cancer can be divided into different stages:
During this stage, abnormal or cancerous cells are limited to the innermost layer of the stomach lining (mucosa) and have not invaded deeper tissues but can spread to nearby parts. This is also called carcinoma in situ.
Stage I stomach cancer is divided into Stage IA and Stage IB, depending on the spread of the cancer and whether nearby lymph nodes are affected.
Stage II stomach cancer is divided into Stage IIA and Stage IIB based on how deeply the cancer has grown into the stomach wall and how many nearby lymph nodes are affected.
Stage III stomach cancer is divided into Stages IIIA, IIIB and IIIC. At this stage, the cancer has grown deeper into the stomach wall and may have spread to several nearby lymph nodes or surrounding organs.
The cancer at this stage has spread from the stomach to other distant parts of the body, such as the liver, lungs, distant lymph nodes or the lining of the abdomen. This stage is also known as metastatic stomach cancer. The cancer that has spread to other organs is the same type as the original tumour. For example, stomach cancer that spreads to the lungs will still have stomach cancer cells and it will be called metastatic stomach cancer8.
If stomach cancer is suspected, doctors may use a combination of tests to confirm the diagnosis, determine the extent of the disease and choose the most appropriate treatment. The common diagnostic tests include:
Stomach cancer treatment depends on factors such as the cancer stage, its location, the individual’s overall health, and whether the cancer has spread to other parts of the body. Doctors may use one treatment or combine several approaches as needed.

Not every case of stomach cancer can be prevented. However, certain measures may help reduce its risk:
Note: These steps may help lower the risk of stomach cancer; however, they may not be able to prevent every case. Your risk can also be influenced by factors such as family history and other health conditions. Speak with a doctor for personalised advice if you have concerns about your risk factors.
See a doctor if digestive problems persist, keep coming back or worsen over time. Seek medical advice for symptoms such as unexplained weight loss, ongoing indigestion, repeated vomiting, difficulty swallowing, loss of appetite, feeling full quickly, blood in vomit or black (or red) stools, unusual tiredness, swelling or persistent abdominal pain. These symptoms can occur with many common digestive problems and do not necessarily mean stomach cancer. However, it is important to consult your doctor for persistent symptoms as this may help find the cause early and ensure appropriate treatment1.

Being aware of changes in digestion and other unusual stomach symptoms can help encourage early medical evaluation. Knowing your personal risk factors and following healthy habits may help lower the chances of developing stomach cancer. If symptoms do not settle or become more severe, seeing a doctor promptly can help identify the cause and guide you to the right treatment.
Stomach cancer is often discovered when persistent digestive symptoms lead a person to seek medical advice and undergo tests such as an upper endoscopy and biopsy. In some cases, it may be found during tests performed for another stomach-related problem1,9.
Stomach cancer can be serious and may become life-threatening, especially when diagnosed at an advanced stage. However, early detection and appropriate treatment can improve the chances of recovery14.
Yes, stomach cancer can cause unintentional weight loss1,4, often due to reduced appetite, feeling full quickly, or the effects of the cancer on the body.
The rate at which stomach cancer develops depends on multiple factors, such as the type of cancer. It can also differ based on the characteristics and stage of the tumour, with some cancers progressing gradually while others may advance more quickly15.
Yes, smoking is linked to a higher risk of developing stomach cancer, as harmful chemicals in tobacco can damage cells in the stomach lining. Quitting smoking can help reduce this risk and improve overall health6,13.
Early stomach cancer may cause few or no noticeable symptoms, so it cannot be confirmed based on symptoms alone. Persistent indigestion, stomach discomfort, loss of appetite or unexplained weight loss should be checked by a doctor. They may recommend tests such as an upper endoscopy or biopsy1,9.

Heart attacks can sometimes be ‘silent’, and simple blood tests may reveal important information about heart damage that might otherwise go unnoticed. One such marker is troponin, a protein that can provide early clues about heart injury.
Changes in troponin levels can help your doctor determine if the heart is experiencing any damage/injury due to events such as a heart attack. But what do normal troponin levels look like, and can there be high troponin levels with no heart attack?
In this blog, we will explore the cardiac troponin test, discuss what level of troponin indicates heart attack, compare troponin T vs troponin I, and explain the key troponin I and T differences to help you better understand these critical heart markers.
Troponin is a protein that is found in the heart muscle cells. Normally, only small amounts of troponin are present in the bloodstream. However, if the heart muscle is damaged, such as during a heart attack, these proteins are released into the bloodstream, causing troponin levels to rise.
Troponin consists of three protein components, T, I, and C. Of these, troponin T and troponin I are primarily associated with the heart (cardiac troponins) and can therefore be used as indicators of cardiac injury1. Since troponin is highly specific to the heart, the troponin test has become the preferred tool for detecting heart injury2.
Troponins I and T are two types of troponin that are used for the same purpose. They are not identical, but are very effective at detecting a heart attack and understanding the prognosis of the individual.
Here are a few similarities and differences between them:
Despite the differences, both troponin I and troponin T can be accurately measured and are reliable indicators of heart muscle injury.
Troponin levels are very low in individuals who are healthy. Higher-than-normal troponin levels indicate that heart muscle may be damaged and is releasing troponin into the blood4. However, this does not, by itself, confirm a heart attack. To diagnose a heart attack, the doctor will interpret the troponin test result along with ECG findings and the individual’s symptoms such as chest pain2.
Because different laboratories use different methods (assays) to measure troponin, the normal range depends on the assay used. The result is interpreted by comparing it with the 99th-percentile upper reference limit (URL) provided by that laboratory. A value above the 99th percentile URL for that specific assay is considered elevated6.
| Troponin Results | Interpretation based on 99th Percentile URL |
| Below 99th percentile URL | Considered within the normal range for that specific test |
| Above 99th-percentile URL | May indicate heart muscle injury7 and should be interpreted along with other parameters like the individual’s symptoms, ECG findings, and repeat troponin measurements |
Troponin levels, if elevated, are usually measured more than once over several hours. A rising and falling pattern, particularly when at least one value is above the 99th-percentile URL, is more suggestive of a sudden heart injury than a stable elevated value7.
High troponin levels with no heart attack are possible and can occur in several medical conditions, such as:
Note: To diagnose acute myocardial infarction (AMI), doctors look for a rise or fall in troponin levels, with at least one value above the normal upper limit (99th percentile), along with other signs that the heart muscle is not getting enough blood. However, a rise or fall in troponin levels indicates acute heart muscle injury, but it does not always mean a heart attack. Other conditions, such as myocarditis, pulmonary embolism, severe infection (sepsis), and very fast or abnormal heart rhythms, can also cause troponin levels to rise and fall.
The troponin test is not typically used as a screening test, as troponin tests are usually done in hospital settings. However, high-sensitivity cardiac troponin (hs-cTn) tests can detect extremely small amounts of troponin in the blood, which enables doctors to diagnose or rule out acute coronary syndromes (conditions such as heart attack that cause sudden reduction/blockage of blood flow to the heart) earlier. Evidence suggests that hs-cTn tests may be of use in identifying the risk of cardiovascular disease in individuals who seem healthy or are asymptomatic2,9.
Preventive cardiac testing is not necessary for everyone, but it may be worth discussing with your doctor if you:
Note: Routine high-sensitivity troponin (hs-cTn) testing is not recommended for people without symptoms. Instead, your doctor may recommend checking blood pressure, cholesterol, blood sugar, and overall heart disease risk.
A heart-healthy lifestyle can help manage key cardiovascular risk factors. You can support heart health by following these tips:
Consult a doctor if you experience symptoms that may suggest a heart problem, such as:
These symptoms require immediate medical attention.

Troponin testing can provide valuable information about heart health and help identify signs of heart muscle injury. Understanding troponin levels can support early awareness of cardiovascular risk. For the most accurate assessment, troponin testing and preventive heart screening should always be guided by a healthcare professional.
Yes, severe emotional stress can, in rare cases, trigger Takotsubo cardiomyopathy (also known as “broken heart syndrome”), a temporary heart condition that may lead to increased troponin levels.12
Yes. During a hypertensive emergency (a severe, sudden rise in blood pressure), the heart may experience significant strain, leading to elevated troponin levels13.
The length of time troponin levels remain high depends on the type of troponin and the cause and extent of the heart injury. In general, troponin I may remain elevated for about 7–10 days, while troponin T can stay elevated for about 14 days after heart muscle damage4.
The cardiac troponin test is highly accurate and the gold standard for detecting heart muscle damage, such as that caused by a heart attack (myocardial infarction)4.
Troponin test results are usually available within 1–2 hours. Once the results are ready, your doctor will explain what they mean and whether any further testing or treatment is needed4.
