Laryngeal cancer is a malignant tumor of the larynx. Therefore, initially, one should consult the otorhinolaryngology department. However, in some specialized hospitals, such as cancer hospitals, there might not be a specific otorhinolaryngology department, but there is a head and neck surgery department, so in that case, one should consult the head and neck surgery department. After surgery for laryngeal cancer, comprehensive treatment including chemotherapy and radiotherapy is required. Thus, post-surgery, if radiotherapy is needed, one should visit the radiotherapy department, and if chemotherapy is needed, one should visit the oncology department. Generally, the decision for surgical, radiotherapy, and chemotherapy treatments is based on the condition of the disease.
