Firstly, thyroid cancer is the most common malignant tumor in the neck area. Therefore, it is recommended to consult with the most professional oncology department for diagnosis and treatment when the disease occurs. If thyroid cancer is operable, surgery can be performed by the head and neck surgery department. After surgical treatment, if radiotherapy and chemotherapy are needed, it is still recommended to see an oncologist for treatment and specific therapies. Thus, different departments may be consulted during different stages of the disease, but the primary recommendation is still to seek treatment from the oncology department.
