After a mamogram I had a biopsy done in late Dec. 2010 that showed I had DCIS with microinvasion. I had an incomplete lumpectomy done in Jan. 2011, followed by another incomplete lumpectomy in Feb. 2011. So on April 1, 2011 I went through a bilateral mastectomy. My oncologist was sure it would by the cure for my breast cancer. The mastectomy was also incomplete. The margins were non-existant and the lab indicated a high grade tumer larger than 2cm., DCIS subtype was solid and micropapillary with comedo-type necrosis. The ER/PR studies were both negative. My oncologist believed no other therapy was needed after the bilateral mastectomy. She told me to seek the advise of a radiation oncologist for a second opinion. I saw a radiation oncologist who recommended 28 days of radition which I recently completed. I'm confused as why my stage is 0, when they keep telling me the type of cancer I have is aggressive. No scan other than the intial mamogram was ever performed. What the next step for me?
