Coffee and exercise may prevent prostate cancer.

The Health Professionals Follow-Up Study show a clear association with coffee and exercise in the prevention of prostate cancer.

Data on 50,000 men that participated in the study shows a common diagnosis of prostate cancer since widespread screening began 20 years ago.  Of these 50,000 men 4,975 cases of prostate cancer were diagnosed according to findings from this study.

While the study found just a weak relationship between consumption of six or more cups of coffee a day and a reduced risk of all forms of prostate cancer (down about 19 percent), the reduction for the aggressive form was much more marked — 41 percent.
