Laryngeal cancer is a common malignant tumor in otolaryngology. Patients with laryngeal cancer often experience coughs primarily because of the presence of tumors at the glottis, which then cause irritative coughs. For patients with the aforementioned symptoms, we should first diagnose the disease using a laryngoscope and CT scans of the throat area. Subsequently, it is crucial to remove the tumor through surgery as early as possible to achieve a complete cure. Post-surgery, patients usually undergo radiotherapy and chemotherapy. In the early stages before surgery, when the patient suffers from severe coughing, medications that clear the throat and benefit the voice can be used to alleviate the symptoms and reduce the patient's suffering. (Medication should be administered under the guidance of a doctor.)
