Hi Yvonne,
hope you're recovering well. Just something to share: I bought a prosthesis fairly soon after my surgery, when I'd only just begun chemo. But I lost a bit of weight thru chemo and now my v expensive prosthesis is way bigger than my remaining breast! So just be aware that lots of ppl gain or lose weight through chemo, but your prosthesis won't. I guess as long as you don't lose weight you should be able to make it work, but if you're already a bit thin, just be careful--maybe keep using a cheap soft-form until yr weight settles...
Go well,
Heather
