In January 2017 researchers from Germany and Australia published their review of the scientific literature to assess the effect of yoga on quality of life, mental health and cancer-related symptoms in women with breast cancer who were either receiving active treatment or had completed treatment. A total of 24 studies involving 2,166 individuals were included in the review. Results showed that yoga appeared to improve health-related quality of life, as well as reducing fatigue and sleep disturbances in the short term. In addition, yoga appeared to reduce symptoms of depression and anxiety.
