USC Surgery / Treatments / Lumpectomy

Lumpectomy is a form of breast conserving surgery that removes the breast tumor and a small rim of surrounding normal tissue. Sometimes the procedure is preceded by guiding a wire into the breast to the tumor to aid the surgeon in properly removing the diseased tissue. Other names sometimes used for this procedure include: partial mastectomy, segmental mastectomy, re-excision and quadrantectomy (the latter meaning that roughly a quarter of breast tissue is removed).

Needle localization

Needle localization means that prior to breast conserving surgery, the patient will have a wire placed into the breast either by ultrasound or mammographic guidance. This wire will direct the surgeon more accurately in finding the tumor and allowing him or her to preserve as much normal tissue as possible.
