Lymph node enlargement in the neck of patients with nasopharyngeal carcinoma usually indicates that nasopharyngeal carcinoma has reached stage II or even stage II or above. However, if the lymph nodes in the neck metastasize, it does not mean that the patient has distant metastasis, but only local lymph node area metastasis. Patients are advised not to panic too much because stage II is not particularly serious, unless the neck mass is large. If the neck mass is larger, most patients have already visited the hospital, so the treatment effect is actually better for enlarged lymph nodes in the neck. The main factors for the development of nasal cancer are as follows: 1. family factors: caused by some family history of cancer or family history of nasopharyngeal cancer; 2. infection virus: more patients are infected with EBV; 3. others: consuming too much nitrite-based food or environmental pollution, etc.
