In a breast lumpectomy, the operation focuses on the breast and possibly the lymph nodes under the arm in the setting of invasive cancer. During the operation, the surgeon usually removes some of the lymph nodes under the arm to check for cancer. This approach is termed a sentinel lymph node biopsy, in which the first few nodes that drain the breast are removed and checked under the microscope. A lumpectomy is also called a partial mastectomy or segmental mastectomy. These are all types of breast conservation surgery, in which the cancer is removed with a margin of normal tissue around it. An excisional biopsy is a surgery for a noncancerous lesion that involves removing an area of breast tissue for diagnostic purposes. This involves removing the lesion in question without a margin of healthy tissue around it in order to make a definitive diagnosis (usually done to rule out a cancer).
