How Exercise Can Help You Deal with Breast Cancer

Introduction

Breast cancer is a condition in which the cells in the breast proliferate out of control. Breast cancer comes in several forms and based on which breast cells develop into cancer, the type of breast cancer is determined1.

It is crucial to realise that the majority of breast lumps are referred to technically as a tumour but may be benign and not cancerous (malignant). Some benign breast lumps can increase a woman’s risk of breast cancer, even if the majority of them are not life-threatening. Any breast lump or change in the breast should be examined by a medical professional to determine whether it is benign or malignant (cancer) and whether it may increase your risk of developing cancer in the future. 

Different areas of the breast may be affected by breast cancer. Connective tissue, ducts and lobules are the three fundamental parts of a breast. The glands that generate milk are called lobules. In order to reach the nipple, milk passes through ducts. Everything is wrapped in and held in place by connective tissue, which is composed of fibrous and fatty tissue. Most breast cancers begin in the lobules or ducts.

Breast cancer can spread outside the breast via lymphatic and blood arteries. Breast cancer is said to have metastasised when it spreads to other areas of the body.

There are several parts to the breast where cancer can start:

Occasionally, breast cancers develop in tissues other than the breast. Sarcomas and lymphomas are the names of these cancers, which are not typically thought of as breast cancers.

Breast Cancer Signs and Symptoms

You must be aware of how your breasts typically feel and look. Mammograms do not always detect breast cancer, despite the importance of routine screening tests for the disease. This implies that it’s crucial for you to check your breasts routinely and look out for any changes.

The most typical sign of breast cancer is a new tumour or lump (although most breast lumps are not cancerous). Breast tumours can sometimes be soft, spherical, tender or even painful and some are painless, like a hard mass with irregular borders.

The following are some of the signs of breast cancer:

There are numerous benign (non-cancerous) breast disorders that can also cause these symptoms. Nevertheless, it’s crucial to get any new breast tumour, lump or alteration examined by a skilled medical practitioner so the cause can be identified and treated, if necessary.

Keep in mind that regular breast cancer screenings are crucial. Breast cancer can be detected early, before any symptoms are noticed, through mammography. You have a better chance of receiving effective treatment if breast cancer is detected early.

Exercising After Being Diagnosed With Breast Cancer

One of the most crucial things you can do to maintain your health after receiving a breast cancer diagnosis is exercise. Exercise or any other home remedies cannot help in eliminating any cancer. However, according to research, women who exercise have a higher quality of life and experience fewer side effects both during and after treatment. Additionally, studies have shown that exercise improves mood, stamina and general health and fitness. These factors are crucial for the health of the mind and body, especially when a person is dealing with something as stressful as undergoing cancer treatment. 

Breast cancer may limit your ability to move your shoulder and arm or carry out daily tasks like getting dressed, taking a shower and combing your hair. Your arm and shoulder’s range of motion may be restricted by pain and stiffness5.

That is why it’s critical to perform exercises to regain movement in your arm and shoulder. Along with that, you will need to focus on exercises for overall fitness. Exercises must also be done in the post-surgery recovery stage to aid in reducing post-surgery side effects and speed up your return to regular activities.

Exercises are especially more crucial if you have radiation therapy following surgery to maintain your arm and shoulder flexible. Your arm and shoulder may still be affected by radiation even after your therapy is over. As a result, it’s critical to establish a regular exercise routine to preserve arm and shoulder mobility following breast cancer radiation treatments.

Types of Exercises

1. Cardiovascular exercise

Also known as cardio, this is a sort of exercise that increases your heart rate and may make you sweat. Exercises like walking, running, rowing, riding a bike or swimming are all very effective cardio exercises. It is advised that patients diagnosed with breast cancer do cardio for at least 30 minutes five days a week (or 150 minutes total). This type of physical activity enhances heart health and aids in maintaining a healthy weight. Many people also find it helpful for stress management and preserving feelings of positivity.

Cardiovascular exercises increase blood flow to all parts of the body, help with better oxygen retention, keep the joints smooth and aid in digestion. They improve sleep quality, which in turn helps with stress management. 

Studies3 can show that breast cancer survivors and those carrying the gene for the same benefit from staying active. Other studies4 have found that the chances of recurrence of cancer are lower among people who exercise regularly. 

2. Shoulder exercise

As explained, breast cancer may limit shoulder movement. The trick is not to go overboard and strain your shoulders. People new to shoulder exercises can try shoulder rotation, plank, shoulder stretch, wall pushups and lifting dumbbells that are not heavier than 1 kg each. 

People who work out in gyms can try dumbbell shoulder presses, arm circles and one-arm dumbbell rows. Talk to your doctor before you hit the gym after your diagnosis or surgery. 

3. Arm exercises

The arms, too, must be exercised so that your daily activities can continue uninterrupted. Simple home exercises that can free up your arm are- tricep dips, wall pushups, bicep curls with gentle weights and plank. 

4. Yoga

Yoga is a great way to stretch sore and aching muscles without causing further injury. Some ‘asanas’ or postures are particularly beneficial for the chest, shoulder and arm muscles- dhanurasana, marjaryasana, uttana shishosana and garudasana. 

For control, stress and anxiety, balasana, sukhasana and viparita Karani will come to your assistance. 

Exercises To Avoid

Some exercises are best avoided when you are ill or recovering. Your body is vulnerable and the best way forward is to strengthen it with limited doses of exercise. 

It is imperative that you avoid-

Tips on Exercise

The start of treatment is not the right moment to start a rigorous fitness regimen. You’ll probably have days when you feel energised and days when you feel more worn out.

Conclusion

Breast cancer requires immediate and categorical treatment. The treatment and, in fact, the diagnosis of cancer can be stressful for the mind and body of the patient. That is why doctors recommend regular exercise to help your body cope with and respond to treatment. Exercise also speeds up recovery post-surgery. Start exercising when your doctor advises. 

Frequently Asked Questions (FAQs)

Can exercising reduce the risk of breast cancer? 

Ans: It is difficult to say for sure if exercise lowers cancer chances. But some studies have found that since exercise regulates the secretion of oestrogen and insulin, it may be beneficial against the development of cancer cells in the breasts. 

Is exercise recommended for people with a breast cancer diagnosis? 

Ans: Exercise is a simple and extremely efficient way to manage pain, improve mobility and control stress. Exercise may not directly cure you, but it will help by keeping your mind and body fit. 

Which exercises will help breast cancer?

Ans: While exercise does not cure cancer, some exercises will help with symptom management and relieve stress. Arm and shoulder exercises like planks, wall pushups, shoulder rotation and yoga will help. Regular cardio activities like power walking, swimming and cycling are recommended based on the patient’s health.

Breast Cancer: Foods to Have and Avoid During and After Treatment

Introduction

Breast cancer is one of the most common cancers in women. It may also occur in men, although very rare. Breast cancers can start from any of the different parts of the breast1. The breast is an organ composed mainly of glands, ducts and fatty tissue. In women, the breast makes milk for feeding newborns and infants.

Types of Breast Cancer

The most common types of breast cancer are2:-

Invasive Ductal Carcinoma

The cancer cells begin in the ducts and then grow outside the ducts into other parts of the breast tissue. Invasive cancer cells can also spread or metastasise, to other parts of the body.

Invasive Lobular Carcinoma

The cancer cells begin in the lobules and then spread from the lobules to the breast tissues that are close by. These invasive cancer cells can also spread to other parts of the body.

There are other types of breast cancers as well, which a doctor usually diagnoses with the help of lab tests and biopsies.

Breast cancer must not be left untreated once diagnosed. The treatment for breast cancer comprises surgery, chemotherapy and radiation therapy. Proper diet and food supplements help in combating and overcoming, partially or otherwise, the side effects of the treatment cycle, especially chemotherapy and radiation.

Best Foods for Breast Cancer Warriors

Good nutrition is the key for cancer patients throughout the various phases of treatment and after. The treatment may affect the way your body metabolises certain foods and uses nutrients and this varies for each individual.

During the treatment process, your diet must help build up your strength. You must eat high protein, high-calorie foods which will promote the following-

Food Recommendations During and After Treatment of Breast Cancer

1. Protein

If you had surgery, chemotherapy or radiation therapy, you need a lot of protein to feel fit and fight off infections. The body loses substantial immunity in the process of breast cancer (and other cancer) treatment. Fish, poultry, lean meat, eggs, low-fat dairy products, nuts and nut butter, dried beans, peas, lentils and soya foods are all good sources of protein.

In my opinion, depending on whether you are vegeterian or follow other diets, increase your consumption of poultry, fish, and legumes like beans and lentils for a healthy source of protein. Scientists suggest daily protein consumption may help cope with breast cancer3. One to two servings of soy food per day, such as tofu, edamame, and soy milk, may also be included assuming soy is used in moderation.

Dr. Rajeev Singh, BAMS

2. Grapes

grapes

Grapes are a rich source of the antioxidant resveratrol, which has the potential to possibly stop cancer from starting in the breast4. You must eat grapes with their skin intact as it has the most resveratrol.

3. Figs

figs

These have always been popular for their medicinal properties. They contain high levels of the flavonoid quercetin beneficial for lung and colon cancers5. Figs can reduce inflammation which is the major cause of cancer. 

4. Broccoli and Cauliflower

Cruciferous vegetables must be included in your regular diet. Broccoli has a high amount of a phytochemical called sulforaphane, which is a cancer-fighting plant compound6. These vegetables are effective sources of nutrition and also boost immunity.

5. Garlic and Onion

The antimicrobial and antitumor properties of garlic and onion have been known for over 1000 years. They must be part of your daily diet.

6. Tea

Tea (both green and black) has active antioxidants that keep the harmful effects of free radicals in check, which cause cellular damage7. Fresh tulsi tea can be a good choice.

7. Turmeric

turmeric

It is already an integral part of Indian foods. Curcumin I, II and III inhibit carcinogenesis and have proven anti-inflammatory properties. It is also an antitumour agent8

8. Rosemary

rosemary

This herb is rich in carnosol, a phytochemical that can slow the growth of cancer cells, strengthen the immune system and limit the production of cancer-related hormones. It acts as an antioxidant and can be included in your diet during and after breast cancer treatment9.

9. Fenugreek

fenugreek seeds

This ingredient in every Indian kitchen helps inhibit tumour cell growth. It is useful for patients with breast cancer and it has anticancer potential10. You may include it in your diet during and post-treatment.

10. Saffron

This exotic flower product has excellent inhibitory properties against cancer cells11.

11. Soya Products

soy proteins

Nutritional properties of soya milk and other soya products make them preferred inclusions in your breast cancer diet.

If you ask me, roughly 25 to 30 grams of fibre should be taken daily. To my knowledge, whole grains are rich in vitamins, minerals, phytochemicals, fibre, and complex carbs. According to a study12, eating a lot of fibre may keep you away from breast cancer and other hormone-dependent tumours. Make sure that at least 50% of the grains in your diet are whole grains, such as brown rice for dinner or whole-grain bread for lunch.

Dr. Siddharth Gupta, B.A.M.S, M.D (Ayu)

Foods to Avoid when Affected by Breast Cancer

Apart from the usual culprits like sugary foods, fatty foods and processed and preserved food, if you suffer from breast cancer, make sure you avoid the following:

Conclusion

The most important part of breast cancer treatment is a regular follow-up, maintaining a healthy lifestyle and following a good diet. Apart from keeping to a diet rich in proteins, minerals, vitamins and nutrients, you must always be well hydrated. Drink plenty of water, exercise and keep your weight in check, as fat and obesity are inimical for breast cancer. Form a habit of taking small meals rather than heavy ones, spaced throughout the day. Do enough activities caring to avoid stress on the arm where the axillary nodes have been surgically removed. 

Frequently Asked Questions (FAQs)

What should a breast cancer patient eat?

Your diet should be such that you eat enough nutrients to keep your body strong. A balanced diet consisting of fruits, vegetables, grains, beans, nuts, seeds, meats/eggs and dairy products is ideal. Talk to your doctor about any additional supplements that you may need.

What are the juices best for breast cancer patients?

Cruciferous vegetable-based juices, i.e. juices that contain vegetables like cabbage, spinach or any other belonging to the family of cruciferous vegetables containing loads of vitamin A.
You may go for any of these juice combinations:
– Orange, carrot, turmeric.
– Green apple, beetroot.
– Beetroot, carrot orange, cucumber.
Make sure to consume freshly prepared juices and not packaged ones. Whole fruits are always better than juices because they include all the fibre content. 

Are eggs permitted for breast cancer patients?

Eggs are rich in powerful antioxidants, lutein and zeaxanthin. It inhibits cancer cell growth in breast cancers. It is good to have an egg a day unless you suffer from any other health conditions and must avoid it.

What food should I take to fight breast cancer naturally?

Berries, broccoli, tomatoes, walnuts, grapes and other coloured and leafy vegetables, fruits and nuts from the list. All plant foods that contain phytochemicals typically comprise foods for fighting your battle against breast cancer naturally.
