A lumpectomy is a surgical procedure used to diagnose or treat breast cancer. The procedure removes the breast lump and a margin of healthy tissue. The rest of the breast is left intact.
A woman is a candidate for lumpectomy if the following conditions apply:
The woman is put to sleep with conscious sedation or general anesthesia. The skin over the affected breast, chest, and upper arm is cleaned. An incision is made around the previous biopsy site and the surrounding skin is removed. The goal is to remove all of the cancerous breast tissue and leave the rest of the breast intact. Bleeding is stopped and the wound is irrigated. A small drain may be placed in the wound. The incision is carefully closed to minimize scarring.
Some lymph nodes under the arm may be removed to see if cancer has spread. This is called an axillary node dissection. It requires a separate incision in the underarm area. A small drain may be used here, too. The incision is carefully closed to minimize scarring. The lymph nodes removed are sent to a lab for analysis.
Bandages are applied and the woman is awakened.
