Ductal carcinoma in situ, or DCIS, is early stage breast cancer. It is considered non-invasive or pre-invasive, stage 0. The cells that line the breast's milk ducts have changed and look like cancer cells have not spread into the breast around them. Most DCIS cases are detected using breast imaging and biopsy, not symptoms. Treatment options include lumpectomy plus radiation or mastectomy.
