What is the procedure called for the surgical removal of one or more lymph nodes?

The procedure known as lymphadenectomy refers specifically to the surgical removal of one or more lymph nodes. This procedure is often performed to examine the nodes for cancer, to treat cancer that has spread to the lymph nodes, or to reduce lymphatic tissue in cases of infection or disease. By removing lymph nodes, healthcare providers can gather important diagnostic information and potentially control the spread of malignancies.

Other terms provided refer to different procedures or concepts. Lymphostomy typically describes the creation of an opening where lymph fluid can drain, while lymphoectomy, though it may suggest a removal of lymphatic tissue, is not an established surgical term like lymphadenectomy. A lymph node biopsy involves the removal of a portion of lymph node tissue for examination but is not synonymous with the complete excision implied in lymphadenectomy. Thus, lymphadenectomy is the precise term needed for the surgical removal of lymph nodes.
