The country’s top doctor is calling for cancer risk warning labels on alcohol. On “Post Reports,” why, and what that could mean for you.Read more:Last week, U.S. Surgeon General Vivek Murthy said in an advisory that studies suggest alcohol is the third leading preventable cause of cancer, contributing to 100,000 cancer cases and 20,000 related deaths each year. For that reason, he says health warning labels on bottles of alcohol should be updated to include a cancer risk warning and that recommended limits for alcohol consumption should also be reassessed, given the increased risk of certain cancers. Today on “Post Reports,” public health reporter Fenit Nirappil breaks down the science behind the surgeon general’s advisory, what it would take to get warning labels amended and what it could all mean for you. Today’s show was produced by Rennie Svirnovskiy with help from Sabby Robinson.
