A meta-analysis, consisting of a review of nine studies and 964 participants, and published in the journal Breast Cancer, found that MBSR shows a positive effect on psychological function and quality of life for breast cancer survivors.
Another study, by Reich et al, published in the Journal of Pain Symptom Management, found clinical effectiveness evidence that MBSR works to improve symptom clusters in breast cancer patients, particularly for psychological and fatigue symptom clusters, with the greatest improvement occurring during the six-week program with sustained effects for several weeks after MBSR training.
