Hey Bon Bon!! Well its a very individual thing I suppose. Everyone is different and no 2 people the same. I had lumpectomy, rads and tamoxifen 2011, recurrence in 2015, another major lumpectomy and nodes out all clear, chemo and now on Arimidex. Im big breasted so my Surgeon of 6yrs said lumpectomy was all that was necessary. Im having a single mastectomy in 2 weeks with Diep Flap recon as I had rads so cannot have implants. Genetic Counsellors found I was negative and like Rowdy, said a double was unnecessary and odds of getting it in my other side were no different to how random it is. So big breasted and opted for one...well to be honest don't want it at all!!! but not doing this again so this will be prevention and the end for me!!! I dont regret the lumpectomies at all it was right for me. Melinda xo
