An analysis of 5108 cases of invasive breast cancer from the African American Breast Cancer Epidemiology and Risk (AMBER) Consortium indicated that African American women who reported current drinking of ≥ 14 drinks per week had higher odds of invasive breast cancer compared with light drinkers (> 0 to < 4 drinks per week) [adjusted OR (AOR) (95% CI) = 1.33 (1.07–1.64)], while those who reported drinking ≥ 7 drinks per week had higher odds of human epidermal growth factor receptor 2 negative (HER2-) breast cancer [AOR (95% CI) = 1.36 (1.09–1.70) [3]. This evidence concerns the gene ERBB2 and breast cancer.
