Does radiotherapy treat tongue cancer?

Radiotherapy may be the main treatment for some tongue tumours, or it may follow surgery when the team needs to treat the original site or nearby lymph nodes. It can also be combined with medicines for selected cancers, or used to ease symptoms when the disease cannot be treated with surgery. The plan depends on the tumour’s location within the tongue, its size, nearby structures, lymph-node findings, and your ability to eat and speak.

Common treatment effects can include mouth soreness, taste changes, dry mouth, tiredness, and difficulty chewing or swallowing. A dental assessment, mouth-care plan, and advice from a dietitian or speech and swallowing specialist can help protect daily function.

Ask how treatment could affect speech, eating, taste, and saliva. Complete any recommended dental care before treatment if there is time. Tell the team about dentures, loose teeth, mouth ulcers, tobacco use, and current eating difficulties. Use the mouth-care and nutrition plan provided, and report problems early rather than stopping food or fluids without advice.

Call the treatment team promptly if mouth pain prevents drinking, swallowing becomes markedly worse, you develop fever, or sores interfere with prescribed medicines. Seek urgent help for choking, severe breathing difficulty, or bleeding that does not settle with gentle pressure. These warning signs need direct assessment.

Is radiotherapy replacing surgery or following it? Will my neck lymph nodes be included? What support is available for speech, swallowing, teeth, and nutrition? How should I manage mouth soreness between appointments?
