[forher]

That does sound very confusing! I am learning about Her2+ cancer myself and don't have answers for you, but I will say that cancers can change. I am surprised she did not get radiation. I had 1 lymph node involvement and had to have radiation. But, I did notice that my pathology report was written up wrong....it said I was hormone positive after my BMX. My onc said it was a mistake. I don't know who to believe.
I also had implant infection and had to have it removed. I only have one now. At the time of my infection and implant removal, I asked my plastic surgeon to check for any cancer. He said there was none. Did she get a second pathology at the time of her implant removal? It sounds like the there was nothing found in the breast tissue. You should get a copy of whatever she is referring to.
I wonder if there is another way to check for ER/PR receptors? Can blood work be done? Or only on actual tissue samples? Are you saying that she has NEW lymph node involvement? But you said she is in remission.
I know, you are asking the q's and I'm asking you q's too! It would be helpful to see a signature with all the history so we can get a clearer picture. I hope I was a little helpful...Anyways, get your hands on any reports from the first biopsy to the BMX and implant removal. Her tissues may have been sampled then.
