Fatigue is the most common and distressing side effect of cancer treatment and persists beyond successful treatment completion in approximately 30% of breast cancer survivors, causing serious disruption in quality of life. Behavioral interventions incorporating physical activity or relaxation/stress management have demonstrated beneficial effects on cancer-related fatigue, although research in cancer survivors is limited. Mind-body interventions such as yoga are extremely popular among cancer patients and offer a promising alternative to traditional treatments. Research is needed to establish the feasibility and efficacy of these interventions in cancer populations, particularly those who are experiencing problems with fatigue.
