Pharyngeal cancer and laryngeal cancer are the same; the onset of pharyngeal cancer in patients is due to the stimulation of long-term smoking, alcohol consumption, and the intake of overly hot foods, causing malignant proliferation of the squamous epithelium in the pharyngeal mucosa, leading to tumor development. For patients with pharyngeal cancer, the first step should be to complete routine blood tests, coagulation function tests, electronic nasopharyngoscopy, and other relevant examinations, and use a biopsy of a pathological slice for diagnosis. The main treatment method for patients with laryngeal cancer is surgical removal, and postoperative radiotherapy can be appropriately carried out to prevent tumor recurrence.
