Lumpectomy

A lumpectomy completely removes all of the tumour, with a rim of normal breast tissue surrounding it. A lumpectomy is also known as breast-conserving surgery.

A breast conserving procedure is usually not recommended if:

  • Your DCIS is large relative to the size of your breast.
  • You have already had radiation therapy to the affected breast.
  • You have 2 or more areas of DCIS in the same breast that are too far apart to be removed through one single surgical incision and still maintain a satisfactory appearance of the breast.
  • You have had an initial lumpectomy that had a positive margin requiring re-excision, if this re-excision margin remains positive, then mastectomy is recommended.
