Recent updates from the AICR (American Institute for Cancer Research) suggest that even one drinking one drink a day can increase your risk of developing breast cancer compared to a woman who doesn't drink alcohol at all. The more you drink , the higher your chances of developing breast cancer. A lot of women struggle putting these studies in context. "Are you saying if I won't drink, I won't get breast cancer?" or "She didn't drink- why then did she develop breast cancer?"
