Laryngeal cancer is a common malignant tumor in otolaryngology. The staging of laryngeal cancer mainly depends on the location of onset and whether there is lymph node metastasis. Symptoms of laryngeal cancer primarily include hoarseness, difficulty swallowing, difficulty breathing, and coughing up blood. Diagnosis can be definitively made through a laryngoscope, laryngeal CT, and pathological biopsy. If detected in the early to middle stages, patients should undergo timely surgical treatment. In the late stage, treatment can include radiotherapy and chemotherapy to extend the patient's lifespan.
