Coffee may lower risk of oral or throat cancer

Drinking coffee may lower your risk for oral cancer.

Researchers with the American Cancer Society found people who drank more than four cups of caffeinated coffee a day had nearly half the risk of dying from mouth or throat cancers, compared to those who only occasionally or never drank coffee.

The study's authors say more research is needed.

Although less common in the U.S., mouth and throat cancers are among the ten most common cancers in the world.

The study is published online in the American Journal of Epidemiology.
