So the next stage begins...

So ...the next stage begins. I had my surgery - lumpectomy and nodes removed last Tuesday and am feeling really well. A bit  of post operative pain but this was mostly due to me over doing things as I felt so good. The good news is I don’t need more surgery. 
I am now waiting on an appointment with the medical oncologist- probably looking at chemo, radiotherapy and hormone therapy- yay
Does anyone have any resources/ information on KI numbers and what these mean.
