The study of nearly 113,000 men and women found those who drank three or more cups of coffee a day had a 20 percent lower risk of basal cell carcinoma than those who said no to Joe.
Caffeine in non-coffee substances was found equally effective. The cause is speculated to be related to caffeine's ability to "kill off damaged skin cells," said Dr. Josh Zeichner, assistant professor of dermatology at Mount Sinai Medical Center in New York. "If you get rid of these cells that are damaged, then they don't have the opportunity to grow and form cancers."
