Okay...went in to have the mammo feeling quite calm. Got called back in for an ultrasound - feeling pretty low and resigned, preparing myself for bad news. Then got called in as the dr wanted to speak to me. Turned out it was just because they couldn't access my Breastscreen films from a year ago and nothing sinister showing. Radiographer was really apologetic saying that she was not allowed to let on that it looked okay. Oh, and I have a dense breast apparently which was why they wanted the ultrasound to be sure.
I saw my surgeon this afternoon and he has reviewed all films and examined me. I also was a bit worried as there seemed to be a slight swelling near my collarbone (maybe - I wasn't sure) but it seems that it's likely to be due to rads and possibly the fact that I hold that side quite tensely now as there's no mass there at all. So, given the all clear.
Also had a brief discussion about reconstruction (tummy flap) - surgeon said that while it's an op that he finds really interesting to do, from a patient's perspective it is a really big deal and he's more than happy for me to sit on it for as long as I want to.
