A new study has added considerable weight to the claim that exercise can lower the risk for colon cancer. Researchers combined and analyzed several decades worth of data from past studies on how exercise affects colon cancer risk, and found that those who exercised the most were 24 percent less likely to develop the disease.
Colorectal cancer is the third most common type of cancer. The study suggests that if the American population became significantly more physically active, there would be over 24,000 fewer cases of colon cancer in the U.S. each year.
The protective effect of exercise held for all types of physical activity, whether that activity was recreational or job related.
