Lumpectomy removes only the breast lump and is followed by radiation therapy. Many surgeons also remove and test some of the underarm lymph nodes for possible spread of cancer.
- Advantages -The breast is not removed.
- Disadvantages -Small-breasted women with large lumps may have a significant change in breast shape. Scar tissue from the treatment may make it more difficult to examine the breast later. There is a possibility of arm swelling.
