Body Weight and Cancer

Can cancer risk be reduced by intentional weight loss, given that excess body fatness increases the risk of cancers at various organ sites, including the bowel?

There is strong evidence that being physically active reduces the risk of various cancer types, and emerging evidence that sedentary behaviour increases the risk.

There is also clear evidence that the greatest change in diet and physical activity across a population can be achieved by combining a policy approach with individual actions.

Although excess body fatness increases the risk of cancers at various organ sites, including the colon and rectum, the risk may be reduced by intentional weight loss.
