The aim of surgery is to remove all of the cancer in the breast. The initial pioneering operation was a quadrantectomy.
This proved to be very successful but was a deforming operation. Excellent cosmetic results are now expected with lumpectomy which is a more modest procedure, performed with meticulous technique with the goal of achieving cancer free margins. When followed by radiation therapy, the risk of recurrence in the breast is low.
