Invasive/infiltrating ductal carcinoma (IDC) is the most common type of breast cancer, accounting for approximately 80 percent of all diagnoses and more than 144,000 new US cases annually. Triple-negative breast cancer (TNBC), a molecularly diverse subgroup defined by a lack of ER, PR, and Her-2/neu expression, comprises about 15 percent of all IDC cases. Black women are twice as likely to present with TNBC, as evidenced by a study evaluating 39,000 women. Read the full story & the medicine behind it.CME Callout
