The main metastatic site of nasopharyngeal cancer is the lymph nodes in the neck and occasionally the lymph nodes in the pre-auricular region. Nasopharyngeal cancer will firstly metastasize to the lymph nodes in the neck, and enlargement of lymph nodes in the neck is the first symptom of nasopharyngeal cancer patients. Nearly half of the nasopharyngeal cancer patients in China often unintentionally find lumps on their necks, and it is only after further examination that they realize it is nasopharyngeal cancer. Occasionally, lymph node metastasis in the area in front of the ear may occur. If the patient has nasal congestion and nosebleed, about 1/3 of the patients will be combined with enlarged lymph nodes in the neck, then nasopharyngoscopy is needed to confirm the diagnosis of nasopharyngeal carcinoma through pathological examination. In this case, nasopharyngoscopy is needed to confirm the diagnosis of nasopharyngeal cancer through pathologic examination. In addition, ultrasound-guided puncture biopsy of lymph nodes can be done to confirm whether the enlargement of lymph nodes is caused by metastasis of nasopharyngeal cancer. If the diagnosis of nasopharyngeal cancer is accompanied by lymph node metastasis in the neck or pre-auricular region, the first choice of treatment is to use local radiation therapy, and chemotherapy can also be added. Besides the neck, metastatic lymph nodes can also be seen occasionally in the pre-auricular region. If there is a painless lump that continues to increase in size, does not shrink significantly after anti-inflammatory treatment, and is hard, with poor mobility, and fuses into a mass, one should go to the hospital for consultation in time.
