In case you need another reason to get up and move, scientists now report a lower risk of 13 cancers in active people.

Researchers pooled data on 1.44 million people (aged 19 to 98) from 12 U.S. and European studies that tracked participants for 7 to 21 years. Compared to people who reported doing the least moderate-to-vigorous activity during their leisure time, those who did the most had about a:

42 percent lower risk of esophageal cancer (adenocarcinoma).

20 to 26 percent lower risk of liver, lung, kidney, stomach, or uterine cancer and myeloid leukemia,

10 t0 15 percent lower risk of myeloma, colon, head and neck, rectal, bladder, or breast cancer:

There was no lower risk of 13 other cancers. On the other hand, being more active was linked to a 27 percent higher risk of malignant melanoma (probably because of sun exposure) and a 5 percent higher risk of local (but not advanced) prostate cancer. For all but a few cancers, liver stomach, and uterine, exercise seemed to have benefits beyond keeping off extra pounds. The lower risk of lung cancer was not seen in people who never smoked.

What to do:  Walk, run, bike, swim, or dance. Just keep moving.
