Exercise and Cancer Risk — What Does the Science Say?
The answer is not definitive, but according to the National Cancer Institute:
There are a number of mechanisms through which physical activity could affect [positively influence] cancer risk [vis-à-vis prevention and survival]. It has been hypothesized that cancer growth could be initiated or abetted by three metabolic pathways that are also affected by exercise: sex steroids (estrogens and androgens); insulin and insulin-like growth factors; and proteins involved with both insulin metabolism and inflammation. Additionally, several non-hormonal mechanisms have been hypothesized to link physical activity to cancer risk, including inflammation, immune function, oxidative stress, and, for colon cancer, a reduction in time that it takes for waste to pass through the gastrointestinal tract.
