Coffee To Beat Prostate Cancer

Having a few more cups of coffee can reduce a man’s risk of dying of prostate cancer, a new study indicates.

While the case for coffee as a preventative for prostate cancer is far from proven, results show a definite link, particularly with aggressive forms of cancer, US News reports.

“I wouldn’t recommend that people change their coffee-drinking habits based on this study,” said Kathryn M. Wilson, a research fellow in epidemiology at the Harvard School of Public Health and lead author of one report. “But if you like coffee, there is no compelling reason to cut back at this point.”

Aggressive Cancer Affected Most

Data collected on 50,000 men showed nearly 10 per cent (4975) were diagnosed with prostate cancer in the 20 years from 1986 to 2006.

But only 846 of those cancers were life-threatening. And 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.

And there was a clear relationship between the amount of coffee consumed and prostate cancer risk, Wilson said: “The more coffee you drank, the more effect we saw.”

Decaf Works Just As Well

The caffeine in coffee doesn’t seem to be the link, since the same reduction was seen for consumption of decaffeinated coffee, she said.

Instead, “it has something to do with insulin and glucose metabolism,” Wilson said. “A number of studies have found that coffee is associated with a reduced risk of diabetes.”

This study is just a starting point for establishing a relationship between coffee and prostate cancer, Wilson stressed.

“We hope that this study drives more research so that we really know what is going on.”
