Going through cancer treatment is a journey of strength — physically and emotionally. Whether you are being treated with chemotherapy, radiation therapy, immunotherapy or targeted therapy, or undergoing surgery, a weakened immune system can impact your overall health and increase your risk for infections. A powerful immune system enables your body to combat infections, recover sooner and endure treatment.
However, here is the truth: Your immunity can wane during cancer treatment because of the treatments (such as chemotherapy) themselves, poor nutrition, stress and lack of sleep. The good news is that you can still help your immune system protect yourself naturally and safely with the correct medical advice and daily practices.
In this doctor-approved guide we’ll explore how to boost immunity during cancer treatment in a safe, pragmatic and effective manner.
Why Immunity Falters in Cancer Treatment
Your immune system consists of white blood cells, antibodies, bone marrow, lymph nodes and other protective aspects of your body. Cancer and cancer treatments can weaken this system by:
- Leukocytopenia (especially neutropenia)
- Affecting bone marrow function
- Making loss of appetite and malnutrition
- Increasing stress and fatigue
- Creating inflammation in the body
This is why some cancer patients become increasingly susceptible to infection, fever, mouth ulcers, coughing and a poor ability to recover.
Consume Immune-Building Foods (According to Your Treatment)
Food is your daily medicine. Your body needs more nutrients to heal and stay strong while you’re being treated for cancer.
Best foods to include:
✅ Protein sources: dal, eggs, paneer, tofu, chicken (as recommended) and fish (if any)
✅ Seasonal fruits: apple, papaya, pomegranate, banana
✅ Vegetables: bottle guard, spinach, carrot, pumpkin, broccoli
✅ Good fats: almonds, walnuts, flax seeds, olive oil
✅ Whole grains: oats, brown rice, roti’s, quinoa
Doctor Tip:
Do not eat raw salads and unwashed fruits if your immunity is very low. Choose vegetables that are well cooked and food that has been properly washed.
Stay Hydrated to Support Recovery
Water helps your body flush out toxins, promotes kidney function and aids digestion — not to mention that it can help moderate side effects of treatment such as dry mouth and constipation.
Best hydration options:
- Normal water (boiled/cooled if needed)
- Coconut water (if permitted)
- Homemade soups
- ORS (if there is weakness or diarrhea)
Sip fluids gradually throughout the day rather than taking big gulps.
Natural Immunity Booster – Concentrate On Good Sleep
When you’re being treated for cancer, sleep isn’t a luxury, it’s a necessity. While you sleep, your immune system restores itself.
Easy ways to improve sleep:
- Keep a fixed bedtime
- Stay away from mobile screen 1 hour before you go to sleep
- Drink warm milk (if tolerated)
- Practice deep breathing before bed
If insomnia is chronic, consult your physician. Never self-medicate.
Keep it Clean & Prevent Infectious (Most Important)
By antitumor treatment preventing is preferred as a medicine.
Follow these hygiene rules:
- Wash hands frequently with soap
- Wear a mask in crowded areas
- Avoid contact with sick people
- Dry with fresh towels, bed linen and utensils
- “Keep your moth clean (oral hygiene is important to prevent infections)”.
Special advice:
If you develop upper, lower respiratory tract infection or fever, chills, sore throat or unusual weakness and bruising report promptly. Fever with low immunity (which many of us have) can turn for the worse and become serious rapidly.
Get Light Physical Activity (If You’re Allowed)
Physical exercise helps the blood circulate and reduces fatigue, supporting the immune system. Even small movements can help.
Safe activities include:
- Slow walking at home
- Gentle stretching
- Breathing exercises
- Gentle stretching or yoga (as long as clearance from your doctor)
Do not engage in rigorous gymnastic exercises, or overexert during treatment.
Manage Stress to Improve Immunity
Stress directly impacts your immunity. Anxiety and depression are not unusual during cancer treatments, but emotional support can make a big difference.
Stress management tips:
- Talk to family or a counselor
- Join cancer support groups
- Meditation for 10 minutes daily
- Listen to calming music
- Avoid negative online information
The mind at peace is more healing than you realise.
If Not Advised by Your Doctor, Do Not Take Supplements
A lot of people begin taking vitamins, herbs and immunity boosters without consulting their doctors. That can be dangerous, as some supplements may affect cancer medicines.
Common supplements patients ask about:
- Vitamin D
- Vitamin B12
- Zinc
- Iron
- Multivitamins
⚠️ Note: Always speak with your oncologist before trying any supplement. Even “natural” products can have side effects or interfere with how well your treatment works.
Keep Your Gut Healthy (Your Immunity Starts Here!)
Much of immunity, after all, depends on the health of your gut. Cancer therapies can upset digestion, leading to acidity, diarrhea, constipation and bloating.
Gut-friendly foods:
- Curd (if tolerated)
- Soft khichdi
- Banana
- Soup
- Steamed vegetables
If you have canker sores or nausea, eat soft bland foods that are conducive to digestion.
Monitor Blood Counts Regularly
Immunity is not only about eating well — it’s also medical surveillance. Your doctor will check:
- WBC count
- Neutrophils
- Platelets
- Hemoglobin
If your lymphocyte and neutrophil counts decline, your oncologist might recommend:
- Growth factor injections
- Antibiotics (if infection is likely)
- Treatment dose adjustment (if required)
This is why the doctor you select really matters.
