Hi Kek, what bad luck getting breast cancer 3 times. On this site you will come across others who had had BC more than once. I have had a bilateral mastectomy, but only had cancer in one breast. This didn't show up on a mammogram, so I was always worried that the same thing could happen again. My cancer was also larger than what they thought they were after, so following a lumpectomy I went back for a mastectomy, and then 9 months later, after recovering from chemo I had the other one off and the start of reconstruction with expanders. I believe the chance of getting cancer following a mastectomy is greatly reduced, but I don't think it is 0%. something like 4% I think. I felt I couldn't really trust a mammogram, so I was happy with my choice, and I haven't had any regrets.
Love Chris xx
