Even minimal exercise may protect against colon polyps.HealthDay (5/8, Gardner) reported, "Even a little exercise may ward off polyps in the colon, which are sometimes precursors to cancer," according to findings presented Sunday at Digestive Disease Week in Chicago. In study, half of the nearly 1,000 middle-aged patients of "different ethnic and racial" groups, who were at "no increased risk for colon cancer or polyps" exercised for "at least an hour a week." About "two-thirds" of the participants were overweight. By performing screening colonoscopies, the researchers found that participants who "exercised one or more hours a week had a 25.3 percent risk of polyps, versus 33.2 percent for those who didn't meet this exercise threshold. ... Also, 'individuals who exercised for at least three years had increased protection from colon polyps,'" said study author Dr. Nelson Sanchez from Memorial Sloan-Kettering Cancer Center in New York.
