Breast Cancer

Cancer is a complex disease. Studies have found that excessive drinking is associated with an increased risk of certain types of cancer, and some have also reported an association between moderate alcohol consumption and an increased risk of breast cancer. Women who have questions regarding alcohol consumption should speak with their physician who can determine what is best for them based on individual risk factors, such as family history, genetics and lifestyle.

The Centers for Disease Control and Prevention (CDC) state that, “over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including cancer of the breast” and that “by not drinking too much, you can reduce the risk of these short- and long-term health risks.”1

The 2016 Surgeon General’s Report on Alcohol, Drugs, and Health further notes that “for breast cancer, studies have shown that even moderate drinking may increase the risk” and that “even one drink per day may increase the risk of breast cancer.”2
