Hi Kathy Jane,
Very similar diagnosis to mine... I rattled my head again and again when diagnosed as eberyone was assuring me lumpectomy would give me just as good of an outcome as mastectomy and in my case tjey were very much against a mastectomy as I suffer from neuralgias and they were ademant that for me it would pretty much guarantee them thus would very adversely affect my long term quality of life.
It sounds like you know exactly where you are at and what you want and need and are going full steam ahead so wishing you all the best for this next stage.
