I'd have to weigh in on the "no" side. I had a mastectomy 10 years ago on my left side and opted for a reconstructive implant. There are more negatives than you can imagine. The scar tissue makes your breasts less sensitive. They don't "feel" like regular breasts. They are harder and heavier (I had a saline implant, maybe silicone is different.) And after all that, my body kept manufacturing infections to get rid of it. In two years, I was on oral antibiotics almost constantly, I was in the hospital on IV antibiotics three times and spent one whole summer with a PICC line giving myself IV antibiotics 3 times a day. I finally said, "enough!" and had it removed and have had no problems since then. My case is probably extreme, but not uncommon.
I you decide to go with implants, though, I recommend my surgeon, Stephen Cahill, DO, without reservation. His work is extraordinary and he is the best. He works out of Select Surgical in Mt. Clemens. Best of luck with whatever you decide.
