Laryngeal cancer usually does not affect the tongue, but if the disease progresses and the lesion invades the hypoglossal nerve, glossopharyngeal nerve, vagus nerve, etc., it may cause uncomfortable symptoms such as limitation of tongue movement, numbness, etc., and the specific manifestation varies from person to person. The larynx includes three parts: supraglottis, glottis and subglottis. When laryngeal cancer occurs, it usually does not affect the function of tongue, but if the laryngeal cancer progresses, it may cause uncomfortable symptoms such as limited movement of tongue, pain, sensory abnormality such as numbness or loss of sense of taste. Supraglottis laryngeal cancer may have symptoms such as foreign body sensation in throat, sore throat, cough, hoarse voice, dyspnea, etc. Supraglottis laryngeal cancer may have symptoms such as dysphagia, hoarseness, dyspnea, hemoptysis, etc. Subglottis laryngeal cancer may have symptoms such as coughing, hemoptysis and dysphagia. Laryngeal cancer needs to cooperate with doctors for treatment in time, pay close attention to the changes of condition in daily life, have balanced nutrition, provide psychological counseling when necessary, and consult doctor in time if there is any discomfort.
