School-age Drinking May Increase Risk of Breast Cancer

According to a new study by researchers at Washington University School of Medicine in St. Louis, if a female averages a drink per day between her first period and her first full-term pregnancy, she increases her risk of breast cancer by 13%.

The researchers also found that for every bottle of beer, glass of wine or shot of liquor consumed daily, a young woman increases her risk of proliferative benign breast disease (BBD) by 15%. Although such lesions are noncancerous, their presence increases breast cancer risk by as much as 500%.

The study is published online August 28, 2013 in the Journal of the National Cancer Institute.
