Hi Sharon,
first of all, sorry I didn't see your message sooner -- I hope everything's okay and that you're recovering well. But I just wanted to say that I was diagnosed on 11Jan11 (memorable date, that) and didn't have surgery until March -- so about seven weeks on. My surgeon assured me that there would be no difference in waiting up to 8 weeks, even though we already knew (from biopsy) that I had lymph node involvement. The tumour was big, 6.5cm (yep that's cm not mm), and aggressive (grade 3). Like you I was really nervous about the long wait between diagnosis and surgery, but in the end I was grateful for those extra weeks -- I got organised, got my team organised, and went on a quick holiday with my partner.
A year on, and I'm good as gold -- fighting fit, feeling great.
Hope you can find ways of dealing with the worry and everything else, it sure isn't easy.
Go well,
Heather
