The Connection Between Cancer and Exercise

It’s no secret that exercising is good for us and provides plenty of health benefits. It’s good for mental health, weight loss, heart health, and more. According to an 11-year-long study done by JAMA Internal Medicine, exercise also reduces the risk of 13 types of cancer. The study involved approximately 1.44 million men and women between the ages of 19 and 98, and it measured how frequently they exercised and the intensity level of that exercise.

Those that were the most active in the study experienced lower risk in 13 of the 26 types of cancer tested; esophageal (42% decrease), liver (27% decrease), lung (26% decrease), and kidney (23% decrease) cancers were the top four. The 10 percent of participants who exercised least were up to 20 percent more likely to develop cancers mentioned in the JAMA study than the top 10 percent of exercisers. Previous research has indicated that exercise contributes to reduced risk of breast, lung and colon cancers as well.

While most cancers were significantly lowered, risk of prostate and skin cancer actually increased. Although there is no apparent explanation for the prostate cancer increase, it is assumed that those who exercised more frequently did so outside, causing them to have a 27% increased risk of malignant melanoma.

Although there is margin for error in this study as it relies on individuals to remember their daily exercise, it still supports that more exercise correlates to lower disease risk.
