What is DCIS, and how is it treated?
Surgery for DCIS Surgery is the first step to treat DCIS. It removes the abnormal tissue from the breast. Depending on how far the DCIS has spread within the milk ducts, surgery can be mastectomy or lumpectomy. If DCIS is spread throughout the ducts, affecting a large part of the breast, a total (simple) mastectomy will be done.

How serious is DCIS?
DCIS is non-invasive because it hasn't spread beyond the milk ducts into other healthy tissue. DCIS isn't life-threatening, but if you're diagnosed with DCIS, you have a higher-than-average risk of developing invasive breast cancer later in life.Feb 4, 2022
Can DCIS spread after lumpectomy?
Will DCIS return or spread? Since DCIS is a noninvasive form of cancer, it does not spread throughout the body (metastasize).
