Effect of Long-term Yoga Practice on Psychological outcomes in Breast Cancer Survivors

AIM Breast cancer has become a pandemic with an ever-increasing incidence. Although better diagnostics and treatment modalities have reduced mortality, a large number of survivors face cancer and treatment-related long-term symptoms. Many survivors are taking up yoga for improving the quality of life (QoL). The present study attempts to evaluate predictors of psychological states in breast cancer survivors with long-term yoga experience. MATERIALS AND METHODS A case-control study recruited early breast cancer survivors, 30-65 years, completing treatment > 6 months before recruitment, and grouped them based on prior yoga experience (BCY, n = 27) or naïve (BCN, n = 25). Demography, cancer history, diet, exercise habits, and yoga schedule were collected and tools to assess stress, anxiety, depression, general health, and QoL were administered. Multivariate linear regression was done to identify predictors of psychological variables. RESULTS BCY had significantly lower stress, anxiety, depression, better general health, and QoL (P < 0.001). Global QoL and trait anxiety were significantly predicted by Yoga practice; depression was predicted by yoga practice, annual income, and sleep quality; state anxiety was predicted by Yoga practice and income; and stress was predicted by Yoga practice and sleep quality. CONCLUSION Results indicate that breast cancer survivors, doing yoga, have better psychological profiles and are able to deal with demanding situations better. The psycho-oncogenic model of cancer etiology suggests that a better psychological state in survival has the potential to improve prognosis and survival outcomes and Yoga may be a suitable practice for staying cancer-free for a longer time.
