Hormone status different after surgery?
Not sure where to ask this. Has anyone heard of hormone status change between the initial biopsy and the surgery? I found info on it possibly changing on mets, but this pathology was done on the breast tissue. The original biopsy pathology was er+ pgr + her-. I did 6 months of treatment, then had surgery. The pathology now says er+ pgr- her-. Did the treatment change it?
I see my surgeons next week, and my MO the following, so I'll ask then. I'm just trying to figure out what I should ask.
