First Oncology appointment - what to expect/ask?

I was diagnosed with lobular in December.  All indications from mammograms, ultrasound and CT scans were that it was small - 2.5cm - and no node involvement.  The surgeon (who is lovely and has an excellent rep) recommended a partial with sentinel node and said that I would definitely need radiation.  He also said that things might change once he went in and the path report came back.  He did a magnificent job of the partial - I was thrilled with it.  Unfortunately, the results from the biopsy were not so good as the tumour was 4.5cm with no clear margins - too big for me to have anything but a mastectomy - and there were 3 nodes involved.  So, back in hospital a couple of weeks later to have the mastectomy and axilliary dissection - all came back clear after that.  That changed the course of treatment, though, and I am now partway through AC and Paclitaxol chemo - 6 months in all.  Radiation will follow and then hormone therapy as the cancer was OR/PR + and HER -.  My surgeon won't consider reconstruction until at least this time next year and I'm still undecided about whether I will do it or not.  I think if I had both breasts off, I wouldn't even consider it, but who knows.  I'll cross reconstructed bridges when I come to them!
It's nice to know the pathway that you are taking but things can change during the course of it.  And the interesting thing about bc treatment now is that it's obvious that one size does not fit all.  
Good luck with your research.
