Scientists recruited about 900 people with colon cancer who’d recently had surgery and chemotherapy. Participants were randomly assigned to one of two groups.

These participants could do any type of exercise, such as brisk walking (aiming for three or four 45-minute walks per week). Over an average follow-up of nearly eight years, the people in the exercise program had about 30% better odds of surviving. One way regular aerobic exercise might protect against both cancer and cancer-related death is by reducing inflammation, which increases the risk of cancer as well as many other chronic diseases.
