Immunotherapy has become one of the most promising advances in modern cancer treatment. Unlike conventional therapies, immunotherapy works by activating the body’s own immune system to recognize and destroy cancer cells more effectively.
While immunotherapy delivers remarkable results for many patients, responses can vary. According to Prof. Dr. Yeşim Yıldırım, Medical Oncology Specialist at Anadolu Medical Center Hospital, supportive factors play a critical role in maximizing treatment outcomes.
“Lifestyle choices and daily habits can significantly influence how the immune system responds during immunotherapy,” says Prof. Dr. Yıldırım.
One of the most important supportive factors during immunotherapy is gut microbiota health.
The Link Between Gut Microbiota and Immunotherapy
The gut microbiota—home to the largest bacterial ecosystem in the human body—is directly connected to immune system regulation. Scientific studies have demonstrated that a balanced gut microbiome can enhance immune responses and, in some cases, improve immunotherapy effectiveness.
Research has shown that in aggressive cancers such as melanoma, patients with a healthier gut microbiota may respond better to immunotherapy, both in laboratory settings and clinical trials. For this reason, daily habits that support gut health may also serve as complementary support during cancer treatment.
10 Habits That May Help Support Immunotherapy
1. Prioritize Green Vegetables
Include gut-friendly green vegetables such as broccoli, asparagus, spinach, leeks, and artichokes in your daily diet to support microbiota diversity.
2. Consume Fermented Foods Regularly
Foods like yogurt, kefir, and pickles help maintain healthy gut bacteria balance and support immune function.
3. Limit Red Meat Consumption
Reducing red meat intake can contribute to improved gut health and a more balanced intestinal environment.
4. Choose Natural Sweet Alternatives
Instead of processed sugar and packaged foods, opt for honey, dark chocolate, apples, mulberries, and sweet potatoes.
5. Use Probiotics Under Medical Supervision
Probiotics may be beneficial when used with a doctor’s recommendation and during appropriate periods.
6. Avoid Unnecessary Antibiotic Use
Excessive or improper antibiotic use can disrupt beneficial gut bacteria and weaken immune balance.
7. Increase Fiber Intake
Support beneficial bacteria with fiber-rich foods such as whole grains, onions, garlic, bananas, hazelnuts, pumpkin seeds, sunflower seeds, beans, and lentils.
8. Prioritize Quality Sleep
Adequate and restful sleep plays a vital role in maintaining a balanced immune system.
9. Stay Physically Active
Make regular physical activity part of your daily routine to support overall immune health.
10. Manage Stress Effectively
Practices such as meditation, breathing exercises, and relaxation techniques help reduce stress and support both mental and physical well-being.
A Supportive Approach to Cancer Treatment
While immunotherapy remains a medical treatment that must be guided by oncology specialists, adopting supportive lifestyle habits may help optimize immune system performance and overall well-being during the treatment process.
On World Cancer Day, raising awareness about both medical advancements and supportive daily practices is an important step toward a more holistic approach to cancer care.
