The trial, in people treated for colon cancer, showed clear evidence that an exercise program lowered the risk of disease recurrence and death.

Following a supervised exercise lowered people's risk of colon cancer recurrence by 28% in an extensive new clinical trial.

An exercise programme for colon cancer patients can cut the risk of dying by a third, a major international trial shows. The researchers said it was "not a large amount" of exercise and any type of workout from swimming to salsa classes counted. The results could change the way colon cancer is treated around the world.
