“People who were consistently active over the course of their adulthood had a lower risk of death from colon cancer than those who were sedentary,” says first author Kathleen Y. Wolin, ScD. “People often wonder around the start of a new year whether exercise really will help them stay healthy or whether it’s already too late. It’s never too late to start exercising, but it’s also never too early to start being active. That’s the message we hope people will take away from this study.”

Wolin, assistant professor of surgery in the Division of Public Health Sciences, says the benefits of starting an exercise program include not just preventing colon cancer and death from the disease, but also reduced risk of heart disease, diabetes and other cancers.
She says the greatest benefits seem to accrue in those who have exercised for the largest percentage of their lives. But it isn’t necessary to run marathons or to work out for many hours every day.
