About to have treatment for DCIS Stage 3

I was diagnosed 5 weeks ago and after trying for reconstruction at the same time as masectomy, have been turned down,due to my weight.

I am so stressed about having a masectomy and as I am large-breasted (42 DD) I am worried about how this will look.

I am also worried that I will not be able to have a reconstruction unless I loose weight (18 stone now). It is all too much to take really and as I have been waiting so long it just feels a bit ‘unreal’ at the moment.
