Biopsy (HER2 3+) vs Surgical specimen (HER2 0)? What this means?
I'm new on this forum. I have this dilemma about my HER2 status.
Pathology report from biopsy gives HER2 3+, while pathology report from surgical specimen is HER2 0. This is very strange as these two results for HER2 are completely the opposite. Is this theoretically possible and what that means, especially in terms of chemotherapy, should I receive one or not? Or maybe one of these two reports are false? Or some other explanation...
Anyone have a clue?
Thank you very much.
