Laryngeal cancer is a common malignant tumor in otolaryngology with a high level of malignancy. Depending on the location of onset in patients, it is further classified into supraglottic, glottic, and hypopharyngeal tumors. When symptoms such as breathing difficulties, sore throat, and hoarseness occur, it is crucial to make a timely and accurate diagnosis using tools like electronic laryngoscopy and CT scans of the throat area, aiming for early detection and treatment. For early-stage laryngeal cancer that has not metastasized, the tumor can be completely removed surgically. With negative surgical margins, supplementary radiotherapy is usually performed. Some patients may receive low-dose chemotherapy to ensure the control of the tumor and prevent metastasis.
