Lumpectomy is the removal of the breast tumor (the "lump") and some of the normal tissue that surrounds it. Lumpectomy is a form of “breast-conserving” or "breast preservation" surgery. There are several names used for breast-conserving surgery: biopsy, lumpectomy, partial mastectomy, re-excision, quadrantectomy, or wedge resection. Technically, a lumpectomy is a partial mastectomy, because part of the breast tissue is removed. But the amount of tissue removed can vary greatly. Quadrantectomy, for example, means that roughly a quarter of your breast will be removed. Make sure you have a clear understanding from your surgeon about how much of your breast may be gone after surgery and what kind of scar you will have.
