(WashingtonPost) - Whether sipping beer, wine or whiskey, women who drink just three alcoholic beverages a week face slightly higher chances for developing breast cancer compared with teetotalers, a study of more than 100,000 U.S. nurses found. The link between alcohol and breast cancer isn’t new, but most previous studies found no increased risk for breast cancer among light drinkers. The new research provides compelling evidence because it followed so many women for up to almost 30 years, experts said.
