Wishing you lots of luck EVS, keep in touch, we can follow each other through recovery!
I'm haing mastectomy tomorrow and they are putting in an expander implant at the same time. I was having chemo first, but abandoned for now due to no effect on tumour. Resume chemo afterwards and radio to follow. They didn't want to put the silicone one just now in due to risk of damage from rads, but told me the expander one may get damaged but would be replaced by a silicone one anyway once treatment finished, or I can have the DIEP recon that I was originally planned for.
