Triple-Negative Breast Cancer (TNBC) is an aggressive subtype of breast cancer in which the cancer cells do not have estrogen receptors (ER), progesterone receptors (PR), or HER2 receptors. It accounts for approximately 10–15% of all breast cancer cases in the United States, with an estimated 30,000–45,000 women diagnosed each year. TNBC is more commonly seen in younger women, African American women, and individuals carrying BRCA1 gene mutations.
