I, too, chose not to reconstruct. I had a double mastectomy in May 2009. I think this was the best decision for me because I am tall and thin. No one can tell. Most all the time I go without any prosthesis.
It is SUCH a personal decision. This just happened to be the right one for me. However, when I made my decision, the "opinion givers" came outta the wood work. I was 43 and single. People were incredibly vocal about the mistake I was making. Crazy, huh? I have loved being boobless and free. I can out-jump my kids on the trampoline. LOL
I feel terrible that anyone feels pressure to do anything that is not in their heart. It is an individual's decision.
Love to you all,
Maureen
