Strong muscles lower cancer risk

Researchers at the University of Alberta used body scan imaging to show that cancer patients with the least muscles lived an average of 10 months less than patients who were more muscular, even after controlling for other variables such as cancer stage and severity (Lancet Oncology, January 2009). This supports many other studies that show people who exercise have lower risk of some cancers and better survival rates.

A possible mechanism is that muscles are the source of the body’s protein which is necessary to make antibodies and cells to prevent cancer from occurring and spreading. Extremely low muscle mass is associated with a poor immunity.
