Does radiotherapy treat voice box cancer?

Voice box cancer is also called laryngeal cancer. Radiotherapy uses carefully planned beams to damage cancer cells in a chosen area. It may be considered when the tumour is localised, after surgery to address remaining risk, or with other treatment when the team is trying to preserve the voice box. The plan depends on the tumour’s exact site, size, spread, and how well the larynx is working. Treatment can affect nearby tissues, so the team plans the field to limit exposure where possible. Possible effects include a sore throat, hoarseness, skin irritation, tiredness, or difficulty swallowing. Some effects settle after treatment, while others need ongoing support.

Ask the head and neck cancer team why radiotherapy is being recommended and what it is intended to achieve. Before treatment, you may be offered dental review, swallowing assessment, and advice about nutrition and voice care. Tell the team about smoking, medicines, previous radiation, or problems swallowing. During treatment, report worsening pain, reduced drinking, coughing while swallowing, or voice changes so support can be arranged early. Do not stop a prescribed course without speaking with the treating team.

Seek urgent medical help for severe breathing difficulty, noisy breathing that is getting worse, inability to swallow saliva, or signs of dehydration such as very little urine and marked dizziness. Contact the cancer team promptly for fever, rapidly increasing neck swelling, bleeding, or pain that prevents drinking. These symptoms need assessment regardless of whether radiotherapy has started.

Which part of my larynx is affected, and what is the aim of radiotherapy? Could surgery, chemotherapy, or another approach be combined with it? How might treatment affect my voice, swallowing, breathing, and nutrition? Who should I contact if side effects make eating or drinking difficult?
