ST. LOUIS — A new study by Washington University in St. Louis supports the role of exercise in reducing colon cancer risk.
Researchers at Washington University School of Medicine and Harvard University analyzed several decades worth of data from past studies on the link between colon cancer risk and exercise.
They found that people who exercised the most were 24 percent less likely to develop the disease than those who exercised the least.
Lead study author Kathleen Wolin, a cancer prevention specialist at Washington University, says the study suggests physical activity protects against colon cancer. It was published Tuesday in the British Journal of Cancer.
Colorectal cancer is the third most common type of cancer.
