Tracey, as my 2nd diagnosis in 2015 was a recurrence, I did chemo finished in December 2016, I didnt do the single mastectomy/diep flap reconstruction until February this year 2017. I had a lumpectomy back then so was all clear and had time to think. My Surgeon and Plastic Surgeon are private but they also work in the Public System too. I was put as a Category 1 as it was my 2nd diagnosis of Breast Cancer which meant I didn't have a waiting period. So it depends on your complete history and diagnosis. I'm also big breasted at a 10E, and the diep flap recon has the left side a little smaller which I love LOL, so he is going to reduce my right side to match. Really happy with the outcome. Definitely worth doing your research and checking with your Surgeon what your options are at the time of Mastectomy. Hugs Melinda xo
