The incision on my lower abdomen goes from the side of the hip to the side of the hip and goes down along the hairline. It is new so I’m not gonna know for a while how it will look.. I’m pretty sure I can wear bikini underwear and it would not show. I have feeling all along The scar. There is no pain. I have read that some people have numbness and pain and that their abdomen is distorted. I have none of that. If you are considering this, the best thing to do is find an excellent plastic surgeon. I found mine by going to a lecture at a local hospital and he was just a wealth of information and brought pics and described how he did things. I felt very safe with him and everything he has told me has been right on. I do not know where you live but would be glad to share his name with you. There is supposed to be a wonderful place in New Orleans with wonderful doctors. I think the key is the plastic surgeon. I think the radiation could damage your breast skin which may affect whether you could have nipple sparing surgery or skin sparing surgery. If you are thinking of having a mastectomy with the diep flap surgery you might reconsider the radiation. I do not know anything about your case and am not a doctor so take this information Lightly. If only one breast is involved then that changes a lot of stuff. Mine was bilateral.
