The symptoms of laryngeal cancer are different according to its location and symptoms. The most common location of laryngeal cancer is the vocal cord, which is the most common type of glottic laryngeal cancer. The symptoms of glottic laryngeal cancer are mainly hoarseness. Therefore, if a person has hoarseness, that is, hoarseness, which lasts for more than three weeks, he should go to the hospital for examination. It may be an early stage of laryngeal cancer. But for supraglottic cancer and subglottic cancer, there are basically no symptoms at the early stage, and there may be foreign body sensation and pain in the pharynx. Subglottic cancer is more hidden and harder to find. When it is found in the early stage, hoarseness or dyspnea are the main symptoms of subglottic cancer. Therefore, subglottic cancer is relatively rare, mainly dyspnea and hoarseness. Therefore, the early performance of different parts is different. Because glottic cancer is the most common type of laryngeal cancer, if hoarseness lasts for more than three weeks, it should be highly suspected of the possibility of laryngeal cancer, and should go to the hospital for treatment.
