Nasopharyngeal carcinoma has metastasized?

Nasopharyngeal carcinoma (NPC) is a malignant tumor that occurs in the neck and side walls of the nasopharynx. The most common metastatic sites of NPC are the liver, bones and lungs. To determine whether NPC metastases occur, clinical symptoms and related tests can be used to confirm the diagnosis. If NPC metastases occur, surgery, chemotherapy and radiation can be used to treat them.
