Answer

Lumpectomy is defined as complete surgical resection of a primary tumor with a goal of achieving widely negative margins (ideally a 1-cm margin around the lesion). It is applicable in most patients with stage I and stage II invasive carcinomas.

Other terms synonymous with lumpectomy include partial mastectomy, segmental mastectomy, and tylectomy. A quadrantectomy is a type of lumpectomy that is defined as complete removal of the entire affected breast quadrant; it is less cosmetically satisfactory than lumpectomy.
