Coffee and Prostate Cancer
Dec. 8 (Bloomberg) -- Drinking coffee may lower the risk of developing the
deadliest form of prostate cancer, according to a Harvard Medical School study.
In research involving 50,000 men over 20 years, scientists led by Kathryn
Wilson at Harvard’s Channing Laboratory found that the 5 percent of men who drank 6 or more cups a day
had a 60 percent lower risk of developing the advanced form of the disease than those who didn’t consume any.
The risk was about 20 percent lower for the men who drank 1 to 3 cups a day, and 25 percent lower for those
consuming 4 or 5 cups.
The study is the first to associate coffee with prostate cancer, contradicting previous research that’s found no
link. The difference may be because Wilson and colleagues looked for the first time at the link between coffee and
different stages of the disease, instead of grouping them all together. More research is needed to confirm the
findings, she said.
“People shouldn’t start changing their coffee consumption based on one study,” Wilson said in a phone interview on
Dec. 5. “It could be chance, and we really need to see whether it pans out in other studies.”
Prostate cancer struck almost 200,000 men in the U.S. this year and killed more than 27,000, making it the
second-deadliest malignancy among American men after lung cancer, according to the American Cancer Society. About
54 percent of U.S. adults drink coffee, according to the New York-based National Coffee Association.
