Did not have any issues with expanders, and waiting for exchange to implants. BUT i started smoking again 3 months after mastectomy/ expanders placed , in expansion now, and up to a pack a day again. Worried what this will do to my outcome if I don't get my act together and quit now? Exchange will be about 6 to 8 weeks from May 31st. I told my doctor and he is concerned as is everyone around me. For some reason I don't feel the urgency to quit like I did when I was going to have Mastectomy. Fill me in.
