Laryngeal cancer is a malignant tumor of the larynx, which is clinically primarily squamous cell carcinoma and belongs to epithelial malignancies. Generally, epithelial malignancies are not contagious. However, laryngeal cancer may sometimes be related to certain viral infections, such as papillomatosis, which might be contagious. This is an aspect of its etiology, but laryngeal cancer itself is not contagious. In summary, laryngeal cancer is not contagious. It is a malignant tumor disease, and its clinical treatment mainly involves surgical intervention, which can be supplemented with radiation therapy and other treatments.
