Does radiotherapy treat throat cancer?

Radiotherapy may be used on its own for selected tumours, after surgery to treat cells that may remain, or with medicines such as chemotherapy when the care team believes combined treatment is appropriate. The plan depends on where the cancer started, its size, nearby lymph nodes, whether it has spread, and your general health. Treatment is carefully shaped so the intended area receives radiation while nearby healthy tissue receives as little exposure as practical.

Possible effects include a sore throat, dry mouth, skin irritation, tiredness, and difficulty swallowing. Your team can offer mouth care, nutrition advice, and medicines to help manage these changes.

Ask the oncology team whether radiotherapy is intended to remove the cancer, reduce it before another treatment, or ease symptoms. Bring a list of medicines and describe any dental problems, swallowing changes, or weight loss. A dental review and a plan for eating and drinking may be useful before treatment begins. During the course, report new mouth pain, reduced intake, or worsening swallowing early so support can be adjusted.

Contact your treatment team promptly if you cannot keep fluids down, swallowing becomes suddenly harder, mouth sores prevent eating, or breathing feels different. Seek urgent help for severe breathing difficulty, choking, or rapidly increasing swelling in the neck. These symptoms need assessment regardless of whether radiotherapy has started.

Which part of my throat will be treated, and what is the goal? Will radiotherapy be combined with surgery or medicines? How can I protect my mouth and maintain nutrition? Who should I contact outside appointments if swallowing or breathing changes?
