Higher levels of leisure-time physical activity may lower your risk for 13 types of cancers, according to a new study published online by JAMA Internal Medicine.
Steven C. Moore, Ph.D., M.P.H., of the National Cancer Institute, Bethesda, Md., and coauthors pooled data from 12 U.S. and European cohorts (groups of study participants) with self-reported physical activity (1987-2004). They analyzed associations of physical activity with the incidence of 26 kinds of cancer.
The study included 1.4 million participants and 186,932 cancers were identified during a median of 11 years of follow-up.
