(Reuters) -Shares of European and American spirits makers and brewers fell on Friday after the U.S. surgeon general called for cancer warnings on the labels of alcoholic drinks. The consumption of alcoholic drinks increases the risk of developing breast, colon, liver and other cancers, U.S. Surgeon General Vivek Murthy said in an advisory. "For certain cancers, like breast, mouth, and throat cancers, evidence shows that the risk of developing cancer may start to increase around one or fewer drinks per day," according to the advisory.
