African-American women that are premenopausal are at higher than average risk to develop basal-like breast tumors, which are usually triple-negative for estrogen, progesterone, and HER2 receptors. Basal-like breast tumors may be high grade and diagnosed at a late stage, requiring powerful chemotherapy regimens.
