Aerobic exercise has the potential to reduce the risk of colon cancer and colon polyps in men, a new study by US researchers says. Lead researcher Dr. Anne McTiernan of Seattle's Fred Hutchinson Cancer Research Center studied 102 men and 100 women aged 40-75 years.
WebMD reports that half the participants were asked to exercise, while the rest were not. Neither group had any change in their diets. Men who exercised showed less cancer-cell growth compared to men who did not. No such difference was observed in women.
