Laryngeal cancer is a malignant tumor in the larynx, and clinically, it is primarily squamous cell carcinoma. The causes of laryngeal cancer are diverse, with major triggers being the irritation from smoking and alcohol, as well as viral infections. Clinically, laryngeal cancer is categorized into glottic cancer, supraglottic cancer, and subglottic cancer. The most common type is glottic cancer, which occurs on the vocal cords, typically affecting one vocal cord; bilateral occurrence is extremely rare. Glottic cancer, or cancer of the vocal cord area, is often detected early because hoarseness appears as soon as the lesion develops, prompting patients to seek early medical attention. Therefore, when detected early, the treatment outcomes are generally better.
