Lumpectomy is the surgical removal of a breast lump and a surrounding margin of normal breast tissue. Lumpectomy usually does not significantly alter the physical appearance of the breast. Mastectomy is the surgical removal of an affected breast and often some or all of the axillary (underarm) lymph nodes and pectoral (chest) muscles. Breast reconstruction is possible in most cases after mastectomy.
