Exercise. The single most effective thing you can do you keep your body healthy.

Nope not just that. Diet, not smoking not drinking will go a long way to reduce your risks too. And also keeping good vitamin D levels (highly correlated with lower cancer risk)

But is that because vitamin d protects against cancer, or because cancer lowers your vitamin D levels?

Or is it because people with higher vitamin D levels probably spend more time outdoors, and are getting more exercise?

I wish it was easier to figure this stuff out.
