ATLANTA, Dec. 18 (UPI) -- People who drank more than four cups of caffeinated coffee a day were about half as likely to die from oral/pharyngeal cancer, U.S. researchers found.
Lead author Janet Hildebrand, an epidemiologist and population expert with the American Cancer Society, and colleagues analyzed coffee and tea consumption among people enrolled in the Cancer Prevention Study II, a study begun in 1982 by the American Cancer Society.
