I need an idea of what to expect

[KRISS]

Hi Ladies
I need an idea of what to expect. I was told on Friday that I was her2+ and ER+ at 4:30 in the afternoon by my surgeons nurse. Of course he will be out all this week and my appointment is not until late afternoon on the 3rd.
I have invasive ductal carcenoma. They removed a 1.2cm tumor and my entire nipple on the 18th. Margins and nodes clear. Stage 1 grade 2. Before the path came back on her2 and er I was just going to do 6 wks of radiation. But the nurse said with the++ that will all change. Is there anyone out there similar to me that could give me a rough idea of what to expect? I know we are all different but my mind is going crazy with all the scenarios. I can't wait 11 days with no feed back. Any info would be much appreciated. Thanks Kriss
PS sorry on being wordy, I am not up on the lingo and abbreviations. Could somone explain those to me as well?
