I haven't had any scans, not even a mammogram. I was diagnosed in April of 2012...stage 2A. No node involvement. Originally had lumpectomy and then decided to have bilateral mastectomy. I had chemo but no radiation. I wondered the same thing but was told I don't need scans unless I feel something. They order blood work once a year (CBC complete blood count) to test levels. I have heard mixed things about that but it does make me feel good to know my levels are all within normal range.
