Go and get yourselves some Nikes instead of chemotherapy.

If you engage in the equivalent of 150 minutes a week of physical activity -- basically, walking before and after [a colon cancer diagnosis] the risk reduction [in all-cause mortality] is 0.58. That is better than any chemotherapy we have ever given to anyone. Physical activity after diagnosis, and certainly pre- and post-, is better, but even if you just pick it up afterwards, you will have a significant improvement in outcome. If you are a couch potato and do not exercise, your risk goes the other way, to risk escalation, with a 1.36 hazard ratio [for all-cause mortality].

150 minutes a week of physical activity  .... is better than any chemotherapy we have ever given to anyone.
