A study of more than 100,000 men and women found that those who drink more than three cups of coffee a day have a 20-percent lower risk of basal cell carcinoma.

Doctors said people should not drink caffeinated beverages by the gallons based on this study. More research is needed to better understand why caffeine cuts the risk of developing a skin cancer that affects 2.8 million Americans each year.
