Michelle, mine was exactly the same....grade III, invasive ductal, strongly ER/PR+, but I forgot if I was her2 ++ or +++. Dr. Wicha had told me then that it was considered "borderline" and not really positive, and that even if I had been stage IV, that I may not have been able to take it. Glad to hear you will benefit from it. It is like a double edged sword...the good news is that you have a great arsenal with herceptin and Tamoxifen. I also had AC, no T (negative nodes).
Ports are a whole 'nother issue. I did not have one for my 4 AC, but others who had one were very happy that they did.
Hang in there and stay dry today!
