THURSDAY, March 26, 2015 (HealthDay News) -- Fit middle-aged men appear less likely to develop lung and colon cancer in later life than their out-of-shape peers. And if they do develop cancer, they are more likely to beat it, a new study suggests.
Nearly 14,000 men underwent treadmill tests at midlife and had their medical records reviewed at age 65 or older. Researchers found that the fitter guys had roughly half the risk for lung and colon cancer compared with unfit men. Their risk for death from these cancers was about one-third lower.
