My decision for a Mastectomy was the hardest one I have made. Agonizing all about the "what ifs". In the end it was really the lack of clarity surrounding the diagnostic tools. The MRI could still only see high grade DCIS and found it throughout my breast. What the MRI found was not connected to the original mass, and without that test it would have been left behind in a lumpectomy to recurr later. This really scared me as I would be one of the very unlucky ladies who had cancer come back into their lives. The second reason was really about my family. I never wanted to face them in the future with recurrance of cancer, and know that I didn't do everything possible at the time to never have it return. So...I decided mastectomy with immediate reconstruction, bilateral, as the chance for cancer in the second breast was 30-50%. Don't know if my breast are high density. I had the 2 lumpectomies July and August. My mast will be around March next year when chemo finishes in Feb. I had 2 IDC tumors, one positive for hormone, one negative. I am not having radio. I have only seen one plastic surgeon at this stage, I am seeing 3 for opinions. This first one prefers implants with muscle over, for the best cosmetic result and lower risk operation. I'm not sure how long the stages are, but a process that will take many months. You are in a really are place right now trying to decide what to do. What helped me was to say "if there is doubt, there is no doubt". Meaning, if you are not sure, then keep asking until you have no doubts left. Then you have your decision. I also read somewhere, when you've made your decision, go with it and don't second guess yourself....or you'll go mad. I'm very happy to share my experiences if it helps you, good luck. Louie
