Exercise Lowers Cancer Risk

If a healthy heart and trim waistline aren’t enough incentive, maybe a lower risk for cancer will inspire sedentary people to get moving. A new study from the National Cancer Institute shows that exercise may significantly lower the risk for 13 different forms of the disease, Time.com reports. Researchers analyzed 11 years of data on the health, diet, and activity of 1.4 million people and found that a higher level of physical exertion was associated with a 7 percent lower overall chance of developing cancer. Just a few hours of weekly exercise had a particular effect on esophageal cancer, lowering the risk for the disease by 42 percent. Working out also cut the risk for lung, kidney, stomach, and endometrial cancers by more than 20 percent and significantly reduced the likelihood that people would suffer from leukemia, colon cancer, or breast cancer. The more active people were, the more their risk dropped, notes study leader Steven Moore. “Cancer is a very feared disease,” he says. “But if people understand that physical activity can influence their risk for cancer, then that might provide yet one more motivating factor to become active. “
