I got into trouble with a group of women once having this discussion...my point was that if you have cancer and can completely go into remission by removing the breast, what's the big deal? It's not like boobs are penises....after nursing children boobs become decorations. Penises on the other hand serve a lifelong purpose.
I know it's a traumatic thing to have a mastectomy but there are worse things...
btw, I didn't get laid that night
