Coffee found to lower prostate cancer risk

Researchers have found that coffee may lower a man's risk of developing the deadliest form of prostate cancer.

Scientists at Harvard University tracked 50-thousand men over 20 years. They found those who drank six or more cups of coffee a day had a 60 percent lower risk of developing the advanced form of the disease.

The prostate cancer risk was 25 percent lower for men who drank four to five cups daily, and 20 percent lower for those who drank one to three cups.

Researchers suspect it's something other than caffeine that's preventing advanced prostate cancer, because they found the same results among those who drank decaffeinated coffee.

They presented their findings at a conference of the American Association for Cancer Research.
