Hi I was diagnosed with Stage 3 Invasive Ductal Carcinoma in Feb. of this year, I finished chemo July 3 and had my mastectomy about 5 weeks ago and im getting ready to start radiation therapy next week, but my question is when I went to tattoo for my radiation, why did the technician tattoo me under my breast of the opposite side I had cancer? Does that mean that when they did CT Scan that it should cancer cells, it did spread to my lymph nodes and they were removed
