What is excision of a lymph node?

Excision of a lymph node, also known as lymphadenectomy, is a surgical procedure that involves the removal of one or more lymph nodes for diagnostic or therapeutic purposes. This procedure is commonly performed to assess the presence of cancer, infection, or other diseases. The removed lymph nodes are often examined histologically to determine any underlying pathology. Excision may be performed as part of a larger surgical intervention or as a standalone procedure, depending on the clinical situation.
