Lumpectomy (aka: tylectomy) is a common surgical procedure designed to remove a discrete lump, usually a benign tumor or breast cancer, from an affected man or woman's breast. As the tissue removed is generally quite limited and the procedure relatively non-invasive, compared to a mastectomy, a lumpectomy is considered a viable means of "breast conservation" or "breast preservation" surgery with all the attendant physical and emotional advantages of such an approach.
