Exercise Can Lower Risk of Some Cancers By 20%

Exercise can have a big impact on the development of cancer.

You know the virtues of regular physical activity: it can lower your risk of becoming overweight and can keep diseases like heart problems and diabetes at bay. But can it help reduce the risk of cancer, too? A new study published in JAMA Internal Medicine sheds new light on that question.

Previous studies have found that people who are more active tend to have lower rates of colon, breast and endometrial cancer. Exercise might lower colon tumors by speeding the transit of waste through the intestines, leaving little time for any potential cancer-causing agents to harm intestinal tissues. And physical activity can lower estrogen levels, which are known to contribute to breast and endometrial tumors. Still, there was plenty scientists didn’t fully understand about the mechanism, if there is one, by which exercise cuts down on cancer risk.

In an effort to get a more complete picture of how exercise and cancer interact, a team led by Steven Moore, a cancer epidemiologist at the National Cancer Institute, took on the ambitious task of pooling data from 1. 4 million people who reported on their physical activity levels over a period of 11 years. Moore matched these peoples’ exercise records with whether they developed 26 different types of cancer.
