I had a Radical Mastectory 65 years ago. The surgeon told me he left extra skin flap incase of excessive swelling. I don't remember any swelling but still have the pouch
in the rear of my armpit. I have complete use of that arm, although there has always been a tightness of the muscle across my chest. Right side simple mastectomy. At the time of surgery, there was just skin across the chest, and just looked like I had never had a breast. Unfortuately, I am a lot heavier today and I have a 1/2 pouch on my chest. Not a breast, just an annoyance. Too old to worry about it. Just glad to be alive. I am 92. I also have two new knees, two new hips, and a shoulder replacement. I had a TAVA (name of Aortic Valve Replacement), two years ago, so I think I have had my quota of surgeries for this century. It would have been lovely if replacement had been available, but unfortunately, it is not possible after a radical (not enough tissue and skin for replacement) and it is much easier to have both breasts gone, than to have just one. With just one breast removed, your bra is always being pulled to the side or up too high. Life is always changing, and you just have to be ready for the next one when it comes.
