In the United States, yoga has become one of the most popular complementary and integrative therapies. Leading medical centers—including Memorial Sloan Kettering in New York and MD Anderson Cancer Center in Texas—have integrated yoga into rehabilitation programs for cancer survivors.
Scientific evidence shows that through breathing, stretching, and meditation, yoga effectively alleviates common post-treatment side effects, reduces stress and inflammation, and enhances overall quality of life.
In Hong Kong, more cancer patients are turning to yoga as supportive therapy. Yoga generally includes three key components: postures (asanas), breathing exercises (pranayama), and meditation practices. Among them, Hatha Yoga is most commonly recommended for cancer survivors due to its gentle, adaptable nature.
Evidence-Based Benefits of Yoga for Cancer Patients
Research demonstrates that yoga can:
- Improve cancer-related fatigue and insomnia
- Reduce anxiety and depression
- Enhance quality of life and mental focus
- Relieve chronic pain and lower back discomfort
- Lower stress hormones (cortisol) and inflammatory markers (IL-6, TNF-alpha)
- Improve irritable bowel symptoms and functional disorders
- Enhance balance and reduce fall risk in older patients
Clinical Research Highlights
- A 2014 Journal of Clinical Oncology study showed that breast cancer survivors practicing yoga twice weekly for three months experienced a 57% improvement in fatigue and significant reductions in inflammation.
- A U.S. randomized controlled trial found that breast cancer patients undergoing radiation therapy who joined three weekly yoga sessions reported better quality of life and lower stress hormone levels compared with those who only did stretching or daily activities.
Safety Guidelines for Cancer Patients Practicing Yoga
- Avoid practice when experiencing extreme fatigue, dizziness, or shortness of breath.
- During radiation or chemotherapy, avoid overstretching the treated area.
- After surgery, wait at least one month before resuming practice, especially for abdominal or pelvic procedures.
- If white blood cell or platelet counts are very low, take extra precautions to avoid infection or bleeding.
- Always rehydrate and rest adequately after sessions.
Conclusion
Yoga is more than exercise—it is a mind-body therapy. For cancer patients, it offers a pathway to improve both physical and emotional health, reduce side effects, and regain a sense of control during recovery. With proper guidance and scientific backing, yoga can empower survivors not only in their cancer journey but also as a long-term lifestyle for health and resilience.
