Physically fit middle-aged men are less likely to develop lung and colon cancer in later life than their out-of-shape peers. Also, if they do develop cancer, they are more likely to beat it. Researchers looked at the notes of 14,000 men who had underwent treadmill tests at midlife. By 65 years or older those who performed well had a significantly lower risk of cancer by one-third lower. Interestingly the chance of getting prostate cancer was not reduced but the chance of surviving it was much higher - read more.

Other studies have also shown smoking increased rectal damage. Clearly smokers after prostate should be strong counselled to quit. Read more | Tips to quit.
