TUESDAY, Oct. 7 (HealthDay News) -- Men who drink a moderate amount of red wine may lower their risk of lung cancer, even if they smoke, researchers report.

"An antioxidant component in red wine may help to prevent lung cancer," said lead researcher Chun Chao, a research scientist with the Kaiser Permanente Southern California Department of Research and Evaluation. "The findings provide an impetus for future research to find out if there is something in red wine that may help to either prevent or treat lung cancer."
