Hi Anne, I also had a double mastectomy. First one due to cancer in Dec 2010, and the next one as a precaution, in September 2011 after all my chemo was over. I have also had bilateral implants, and am very happy with the result. My first tumour never showed up on a mammogram, and it was lucky that I found it, 3 months after a clear mammogram. I would find it hard to trust a mammogram again, so figured this would save me lots of anxiety. I have not once had any regret about making this decision. As I planned my second mastectomy, I had another mammogram and ultrasound prior to seeing my surgeon. The mammo was clear, but a suspicious lump showed up on the ultrasound. It was like history repeating itself, and how I regretted not having had them both removed at the same time. I endure a core biopsy this time and an anxious wait for results. This time it was benign, but if ever there was a sign that I was about to do the right thing, it was this little scare. I never doubted my decision after this. Good luck. Love Chris xx
