Nasopharyngeal carcinoma is a malignant, occupying lesion that occurs in the nasopharyngeal area, and clinically it is mainly squamous cell carcinoma. Relatively speaking, although this tumor is malignant, its degree of malignancy is relatively low, especially when compared to liver cancer, lung cancer, and other malignant tumors. The definitive diagnosis of any tumor primarily relies on histopathological diagnosis, which means that pathological examination is the gold standard. In the case of nasopharyngeal carcinoma, we can make a pathological examination by using nasopharyngeal biopsy tissue with forceps under nasendoscopy. If cancer cells are found, then it is essentially confirmed. Of course, other examination methods, such as CT and MRI, are also helpful in diagnosing nasopharyngeal carcinoma and determining whether there are any metastases.
