Laryngoscopy can not directly judge whether the patient has tonsil cancer or not, after laryngoscopy, it can only observe the surface of tonsil clearly, for example, whether there is any ulcer, or whether there is any obvious malignant tendency, but the final diagnosis of tonsil cancer often needs to take the pathology, and the return of the pathology result will be the gold standard of diagnosis. It is suggested that patients can consider going to the hospital for detailed examination if they have uncomfortable throat in their life. Sometimes patients can cooperate well with opening their mouths, but sometimes the pharynx and throat may be involved relatively speaking, and this kind of situation often needs to do laryngoscopy, which is able to observe more carefully. If the tonsils can have the possibility of malignant changes, must take pathology to clarify the diagnosis, if necessary, the tonsils can be removed to send a large pathology.
