Human epidermal growth factor receptor-2 (HER2), a member of epidermal growth factor receptor (EGFR) family, is overexpressed in about 25% of invasive breast cancers and its expression is positively correlated with vascular endothelial growth factor (VEGF)-associated high vascularity of within solid tumor [13, 14]. This evidence concerns the gene VEGFA and invasive breast carcinoma.
