It would be lovely to have one of these BC nurses who seem to work wonders but if like me, you don't, ring your surgeon's office to find out what's going on (even if it's just to find out who you've been referred to so you can ring them) and if you get no joy, talk to your GP.
I had my second surgery on 8/1 and the path report from a few days prior to that was what indicated that I would need chemo. My first treatment was scheduled for 5/2 which was the earliest that it could be done after surgery. As far as I know, this was to ensure healing rather than convenience for the doctors. In fact, the onc squeezed me in for the first consultation before he went on holiday so that there would be no delay when I got the all clear to go ahead.
