Quality of Life and Breast Cancer: How Can Mind⁻Body Exercise Therapies Help? An Overview Study.

Breast cancer survivors experience extensive treatments, threatening their quality of life. Complementary therapies used as a supplement to cancer treatment may control symptoms, enhance quality of life, and contribute to overall patient care. Mind⁻body exercise therapies might motivate cancer survivors to exercise, and assist them in regaining health. The purpose of this overview study is to study benefits from mind⁻body exercise of yoga, tai chi chuan and qigong upon quality of life in breast cancer populations. A systematic overview of reviews was applied. Literature search in five electronic databases and in reference lists was performed during April 2017. In addition, experts in the field were consulted. Of 38 identified titles, 11 review articles, including six meta-analyses were found eligible for review. Methodological quality was high for the majority of quality domains. Yoga, the most studied mind⁻body therapy, was found to benefit breast cancer patients' psychological quality of life, while less support was established concerning physical quality of life elements. The evidence of improvements of quality of life from tai chi chuan and qigong remains unclear. Breast cancer survivors' experiences of psychological and social well-being may be enhanced by practicing yoga.
