Health Alert WEB EXCLUSIVE: Metastatic Breast Cancer: Part 2

BRIDGEPORT, W.Va. (WDTV) -- Question: What are the different kinds (subtypes) of metastatic breast cancer?

MGN

Answer: Subtypes for early stage and metastatic breast cancer are the same: An estimated 65% of patients have Hormonal (estrogen or progesterone driven), also called ER+/PR+; 20% have Her2+(fueled by a protein identified as Her2 neu) and 15% have Triple Negative Breast Cancer (TNBC- which does not have any of the 3 above known biomarkers: ER. PR or HER2). These numbers are approximate, because some people have more than one subtype ( HER2+ and ER+) or their subtype may change over time.
