New research shows those who down a lot of java have a lower rate of head and neck cancers.
In this report, scientists pooled results from nine earlier studies which also included tea drinkers.
The overall the risk of developing head and neck cancers was 12 percent lower in coffee drinkers, and the more coffee people consumed, the lower the risk.
Researchers said there are thousands of chemicals in the popular beverage, so it is difficult to speculate at this time why coffee might be protective.
Details are in the journal Cancer Epidemiology, Biomarkers and Prevention.
