Sentinel Node Biopsy Topic Guide
Sentinel Node Biopsy: A sentinal node biopsy is the surgical removal of one to five lymph nodes closest to a cancerous tumor -- usually breast or skin cancer (melanoma) -- in order to figure out the stage of the cancer, that is, how advanced the cancer is.
Lumpectomy Lumpectomy is surgery to remove a suspected malignant (cancerous) tumor, or lump, and surrounding tissue from a woman's breast. The size and location of the lump determine how much of the breast is removed. Lumpectomy replaced radical mastectomy to because it leaves the breast mostly intact. After surgery, radiation therapy or chemotherapy may be recommended.
