Hi unknown. I had a single skin saving mastectomy In June with immediate reconstruction using implant. I don't have a medical reason at this stage for mastectomy on the other breast so my surgeon has suggested a reduction in size with a smaller implant to match my rebuild! I don't know when that is going to be scheduled but I have my next appointment with my surgeon in February. She was saying that there was a recommendation that any matching surgery be done two years after the initial surgery so that there is healing time and active treatment has finished. Again don't know if that is across the board or just at the hospital she works at. Xx
