Moderate Drinking Linked to Breast Cancer Risk

November 6, 2011

A study recently published in the Journal of the American Medical Association has found a correlation between the consumption of alcohol and increased risk of breast cancer. The data showed that even low-levels of drinking (3-6 glasses of wine per week) led to a 15% increase in breast cancer risk and that women who consumed higher levels of alcohol (at least 2 drinks per day) were found to have a 51% increase in breast cancer risk when compared to women who did not drink alcohol. The study spanned nearly 3 decades and involved more than 100,000 women.

Dr. Wendy Y Chen of Brigham and Women’s Hospital and Harvard Medical School and her colleagues cited alcohol’s effect on circulating estrogen levels as a possible, while unconfirmed, explanation for the correlation between levels of alcohol consumption and risk of developing breast cancer.
