Hi Jane. Its a terribly decision to make and you will make the right one. I had a choice of single or double mastectomy. Lucky I had over xmas to think about it. I would change my mind daily. My decision was made when I had an MRI. The surgeon wanted to make sure nothing was missed on my left breast when I had mammagram and ultrasound. The report came back no cancer but extremely dense breast tissue. Same as the right breast. Cancer can b easily missed with dense tissue. That made my decision to have bilateral. I am very happy with my decision as I wouldn't want to be doing it again as some women have. It honestly hasnt bothered me loosing both. At least i'm even . I just wanted the cancer gone and not grow in the othet breast. You will come to your decision. Dont be influenced by others. Its your body. My other is fine. He'd sooner have me than boobs he said. Good luck. Airlie x
