March 3 is Triple Negative Breast Cancer Awareness Day. It is now commonly understood that most breast cancers are characterized by the presence of three receptors (proteins found inside or on the surface of breast cells): estrogen, progesterone and HER2. These receptors are not “expressed” in women with triple negative breast cancer – hence the name. Since most treatments available today are aimed at those receptors, TNBC is difficult to treat, and the tumors are often more aggressive. TNBC represents approximately 15 percent of all breast cancer cases.
