Laryngeal cancer is a type of malignant tumor located in the larynx and is a common malignant tumor in otolaryngology, characterized by a high degree of malignancy and a tendency for early metastasis. Patients with laryngeal cancer primarily exhibit symptoms such as hoarseness, difficulty swallowing, and in later stages, breathing difficulties. Early detection and diagnosis of laryngeal cancer can lead to cure in most early-stage patients through treatments like laser surgery or open surgery. For mid to late-stage patients, in addition to surgical treatment, postoperative radiation and chemotherapy are generally required to manage symptoms and prevent metastasis of laryngeal cancer.
