It is no fun to wear a prosthesis. You are always so uncomfortable with it riding up or it is so hot. With a breast reconstruction you can do all the things (like swimming, etc.) that you could not (or would not) do without a breast.
I am very happy with my reconstruction. Just be realistic though. It will not look like your other breast for awhile and you do have scars. I had radiation, chemo, and breast removal. It has been great to have something to put back in place. Overall I am very pleased with my results.
