Exercise may raise your odds of surviving breast or colorectal cancer.
Researchers at the National Cancer Institute reviewed 23 studies that tracked 37,500 breast cancer patients for 3 to 13 years. Those who got regular exercise were less likely to die, even if they didn’t start exercising until after their diagnosis. Exercise may help by lowering insulin levels, curbing inflammation, and strengthening the immune system.
“Adequate physical activity should be a standard part of cancer care,” wrote Edward Giovannucci of the Harvard School of Public Health in an editorial published with the study.
