Exercise: Midlife Fitness Reduces Cancer Risk in Men.
Middle-aged men who are fit appear less likely to develop lung and colon cancer when they reach their later years. After treadmill testing nearly 14,000 men, researchers found that the more fit participants had roughly a 50% lower risk for lung and colon cancer and a 30% lower risk of death from such cancers when compared with the least fit men in the study. Lead researcher Dr. Susan Lakoski writes, “Importantly, fit men who developed prostate cancer in the current study had a lower risk of dying of cancer or cardiovascular disease. This speaks to the importance of being fit in midlife to improve survival, even if a man ultimately develops lung, prostate, or colorectal cancer.” JAMA Oncology, March 2015
