Exercise activities like swimming -- when done for about an hour per day -- can lower the risk of colon cancer, according to a new study. Even two hours of less-strenuous activity like housecleaning or similar lower-intensity exercises can also have an effect on lowering the risk of colon cancer.
A team of international scientists analyzed the impact of physical activity on the risk of colon cancer, and the data studied concluded that people with the highest levels of exercise were 22 percent less likely to develop that often-deadly form of cancer.
Exercise had the largest impact in cutting colon cancer risk in people of normal weight, but exercise was also beneficial to a lesser extent in men and women who were overweight or obese. Oddly, exercise did not have a protective effect against rectal cancer in the same study's results.
Estimates in developed countries state that colon and rectal cancer are among the most common cancers, with more than 940,000 cases being diagnosed each year. However, about 492,000 people will die from colon and rectal cancer as a result of being diagnosed.
