My wife recently had a double mascetomy for a breast tumior. Expanders were put in at that time. She is a smoker and did not have time to quit before the surgery. The plastic surgeon warned here of dead tissue during the healing process/recovery if nicotine was in her system,. She is very worried that she will find dead tissue under the bandages when they come off. She is trying to find out if anyone statistics are out there on the percentage of women who smoke and it has shown up in the incision scar. Make sense? I probably could have worded it better. Her doctor really scared her about the black/dead tissue...
