Laryngeal cancer is a malignant tumor in the larynx, clinically mainly squamous cell carcinoma. The treatment of laryngeal cancer primarily involves comprehensive treatment centered around surgery, which is adapted according to the type of laryngeal cancer the patient has and the extent of the lesion. For some early-stage tumors, such as carcinoma in situ or T1 stage tumors, treatment often involves local removal with a laser or radiation therapy, after which a cure is achieved without the need for partial or total laryngectomy. This approach preserves the function of the larynx, especially the function of phonation. In summary, the treatment of laryngeal cancer should be based on its specific circumstances and does not necessarily involve the removal or excision of the larynx.
