Laryngeal cancer is not contagious. Current medical evidence and research indicate that laryngeal cancer does not have a definitive contagious nature. There are many factors involved in the onset of laryngeal cancer, and clinically, the possible inducing factors have not been completely determined yet. These factors may include having a family history, or frequent exposure to radioactive or chemical substances, as well as potentially due to long-term smoking and drinking, which are risk factors that could lead to the disease. Overall, the exact cause of the disease is not particularly clear, but regardless of the factor, no contagious nature has been found. Therefore, laryngeal cancer is not infectious and is not considered a communicable disease. In terms of treatment, surgery is primarily considered, and some cases may also require consideration of radiotherapy or chemotherapy. Generally, it is regarded as a relatively common malignant tumor of the head and neck.
