@Indexia - after a double mastectomy and diep reconstruction - I believe that most specialists do not recommend mammograms, as I guess, with the tissue coming from the tummy, it isn't breast tissue - and they don't want to damage it, as the pressure from the mammogram is quite severe. (Same with women having breast inserts - they don't have mammograms either, for the same reason.)
With a Lumpectomy - sure - mammograms and ultrasounds are definitely recommended yearly to start off with - but I am unlikely to go back to BreastScreen, even after I finish with my Oncologist, as they missed my cancer, twice. I'll be seeing the radiology dept that I've been going to since my diagnosis 6 years ago .... as they have my full history up there, including 4 subsequent biopsies on the same breast.
Most women can go back to BreastScreen after they finish seeing their Medical Oncologist - usually after about 5 years.
