Vigorous Exercise Prevents Prostate Cancer

Exercise prevents colon and reproductive cancers in men and women. Mark Magbanua and colleagues from the University of California, San Francisco, in a study of 71 men with a low risk of prostate cancer, showed that genes controlling cell cycling and DNA repair were upregulated in men who participated in three or more hours of vigorous activity per week. Both the duration and intensity of exercise were important. Regular exercise reduces the risk of death from all causes. The effects of exercise on cancer risk are not clear. It appears that both inactivity and overtraining can influence the risk of some cancers. (Cancer Causes Control, 25:515-523, 2014)
