Molecular Subtypes of Breast Cancer - HER2-enriched: Microscopic photo showing a high grade invasive breast carcinoma. The tumor cells are negative for ER (estrogen receptor)(see insert), and negative for PR (progesterone receptor)(see insert). HER2/neu is overexpressed (see next image), and Ki-67 (proliferation rate) is high. Image courtesy of: Jian-Hua Qiao, MD, FCAP, Los Angeles, CA, USA.
