Abbreviation for triple-negative breast cancer.
Full Definition
TNBC is the standard medical abbreviation for triple-negative breast cancer, a breast cancer subtype that lacks estrogen receptors, progesterone receptors, and HER2 protein overexpression. This abbreviation is widely used in oncology literature, medical records, and clinical protocols. The term emphasizes the absence of three key biomarkers that typically guide targeted therapy decisions, making TNBC a particularly challenging subtype to treat.
