Love your Pinot Grigio nightcap? You’ll want to hear this. A new study in the Journal of the American Medical Association (JAMA) reports that women who consumed three to six drinks a week over several decades were 15 percent more likely to develop breast cancer than non-drinkers. That’s certainly no reason to panic (the risk is still relatively low; for example, that would raise the average risk level from about 2.8 percent to only 3 or 4) but it’s worth noting. But heavy drinking—at least two drinks per day—is associated with a 51 percent increased risk. So if that better describes you, then yes, it’s definitely time to cut back.
