Laryngeal cancer is a common malignant tumor in daily life. Its occurrence is due to factors related to long-term smoking, drinking, and stimulation from physical and chemical factors in the air or work environment. For patients with laryngeal cancer, it is usually necessary to make a definitive diagnosis through examinations such as electronic nasopharyngoscopy, electronic laryngoscopy, and CT of the larynx. Particularly when the patient presents symptoms such as hoarseness, cough with blood, and breathing difficulty, it should draw the patient's attention to seek timely medical examination at a hospital, aiming for early detection and early treatment.
