For tumours in the nasal cavity, oral cavity, throat or neck, radiotherapy can be used following surgery or, occasionally, as the sole treatment measure. The treatment of advanced head/neck tumours is generally carried out using combined techniques and thereby requires close cooperation between doctors from various disciplines (ENT medicine, radio-oncology, internal oncology), right from the time of diagnosis. Tumours which also affect lymph nodes require combined treatment with post-operative radiotherapy.
Radiotherapy is primarily considered for use as the sole method of treatment when surgery is not possible due to the size of the tumour, or in order to avoid complex, extended surgery (e.g. removal of the larynx resulting in the loss of the voice).
