BrCa’s tumors are classified into the following categories: Estrogen Receptor (ER+) which includes luminal A and B subtypes, human epidermal growth factor (HER2)-enriched, and triple-negative BrCa (TNBC), the last of which encompasses the basal-like and claudin-low subtypes [7]. Here, ERBB2 is linked to invasive breast carcinoma.
