The U.S. Surgeon General is calling to add cancer warning labels to alcohol. In a recent advisory, U.S. Surgeon General Vivek Murthy called on Congress to include a cancer risk warning in the warning labels on alcohol. He says alcohol is the third-leading preventable cause of cancer in the U.S., behind tobacco use and obesity.

The top U.S. health official is calling for all alcoholic beverages to carry a warning label about cancer risk.

Dr. Vivek Murthy’s report cites studies linking alcoholic beverages to at least seven malignancies, including breast cancer. But to add warning labels, Congress would have to act.
