Breast Cancer DCIS

Facts about ductal carcinoma in situ (DCIS):

  • Ductal carcinoma in situ (DCIS) refers to cancer of the milk ducts that is confined to the milk ducts and has not spread outside the ducts.
  • DCIS tends to spread along the milk ducts.
  • DCIS also can be multifocal: meaning that it can appear in more than one portion of the breast.
  • Overall, DCIS is a more treatable form of cancer than infiltrating (or invasive) ductal carcinoma.
  • When DCIS is small and localized to one area, treatment will usually involve simple lumpectomy.
  • Radiation therapy may be offered in some cases following lumpectomy.
