A systematic review and meta-analysis brought together 49095 colorectal and breast cancer survivors.
“Each 10 metabolic equivalent task-hour/week increase in post-diagnosis physical activity (equivalent to current recommendations of 150 min/week of at least moderate intensity activity) was associated with 24% decreased total mortality risk among breast cancer survivors and 28% decreased total mortality risk among colorectal cancer survivors. Breast or colorectal cancer survivors who increased their physical activity by any level from pre- to post-diagnosis showed decreased total mortality risk compared with those who did not change their physical activity level or were inactive/insufficiently active before diagnosis. CONCLUSION: Physical activity performed before or after cancer diagnosis is related to reduced mortality risk among breast and colorectal cancer survivors.”
