Yoga Program Shows Promise for Cancer Survivors' Mental Health
A randomized trial led by the University of Rochester Medical Center has found that a structured, four-week yoga program significantly reduces insomnia, fatigue, anxiety, and mood disturbances in cancer survivors. The findings were presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting.
Study Demographics and Design
The study included 410 adult cancer survivors (average age 54). The participant group was largely homogeneous, consisting of:
- 75% breast cancer survivors
- 96% female
- 93% Caucasian
- 82% with some college education
Participants were assigned to two groups: standard survivorship care, or standard care plus the Yoga for Cancer Survivors (YOCAS) program. The YOCAS program consisted of two 75-minute instructor-led sessions per week, combining Gentle Hatha and Restorative yoga poses, breathing exercises, and mindfulness training.
Measurable Improvements
Based on patient questionnaires, the yoga group showed significant improvements across several measures:
- Moderate-to-large reductions in overall mood disturbance
- Small-to-medium reductions in anxiety
- Medium-to-large reductions in fatigue
Improvements appeared linked to yoga's effect on sleep quality. No serious adverse events were reported.

Limitations and Next Steps
The researchers noted several limitations, including the preliminary nature of the findings, the homogeneous sample, the exclusion of metastatic cancer patients, and the short study duration (four weeks).
Looking ahead, researchers plan to adapt the YOCAS intervention via a mobile app for rural communities. They emphasized the importance of consulting certified instructors with experience working with cancer patients for safe and effective practice.
