What studies found

Pooling 12 cohorts, the most active people had lower risk of 13 of 26 cancers, including colon, breast, endometrial, lung, liver, kidney and bladder, and 7% lower cancer risk overall. Most links held regardless of body weight.

The catch

This is observational. For lung cancer the National Cancer Institute calls the effect unclear, because smokers and nonsmokers differ in how active they are. The same study saw slightly more diagnosed prostate cancer and melanoma among the most active; for prostate, fitness studies point the other way.

What to do

Aim for 150–300 minutes of moderate activity a week. See the Exercise section.
