I was diagnosed September 1 with a 7 cm grade 3 DCIS lesion. I had such a disconnect between my diagnosis (since they kept telling DCIS cannot spread) and the recommendation for a mastectomy. I just, in my heart, could not understand why I needed to go through that if this could not spread. Of course in my research I learned that in it's purest form, DCIS cannot spread because it is considered contained within the milk duct. I also learned, that with a grade 3 and large size, it was unlikely to stay contained! So it was really hard after I met with the plastic surgeon who told me she doubted I would be happy with the cosmetic result of a single mastectomy with reconstruction. So I made the decision to have a double mastectomy. My heart had no peace with that decision and in the end, since I did not have a genetic marker for breast cancer, I decided the risk and loss of sensation were too high a price to pay for a non-spreading cancer treatment for one breast! I am so happy with my decision. I told the plastic surgeon that I was sorry I made her job harder, but that I believed her to be an excellent surgeon who was up to the challenge! What they accomplished with the mastectomy side is nothing short of amazing. Now to heal and move on to making them match!
