Increased physical activity is associated with lower risk of 13 types of cancer
Previous studies that had examined associations between physical activity and cancer risk showed that people who engage in more physical activity have reduced risks of developing colon, breast, and endometrial cancers. However, research results were inconclusive for other cancer types due to small numbers of participants in the studies.
IRP researchers led by Steven Moore, Ph.D., M.P.H., pooled data on 1.44 million people from 12 prospective U.S. and European cohorts and found that increased leisure-time physical activity is associated with lower risks for 13 cancer types (esophageal adenocarcinoma, liver, lung, kidney, gastric cardia, endometrial, myeloid leukemia, myeloma, colon, head and neck, rectal, bladder, and breast). Most of the associations were evident regardless of body mass index or smoking history.
The team’s findings confirm and provide specific evidence that physical activity has significant positive effects on cancer risk and should play a key role in population-wide cancer prevention and control efforts.
