According to immunohistochemistry (IHC) classification, BC can be roughly divided into the luminal A subtype, luminal B subtype, human epidermal growth factor receptor 2 (HER2) overexpression subtype, and triple-negative breast cancer subtype (TNBC) (Stovgaard et al., 2019). This evidence concerns the gene ERBB2 and triple-negative breast carcinoma.
