I had a skin sparing masectomy, and have a bulge in my underarm area. It is called a, " dog ear". You can have them across your breast scar, as well. Women who have large breasts, and body fat will have more of a problem with this. My surgical nurse said I can get a breast reconstruction plastic surgeon to reduce the appearance. My dog ear is not that bad, so I am leaving it. But, there is help.
