What to expect from radiotherapy for throat cancer

Planning scans show the tumour and nearby structures so the team can shape treatment to the intended area. A fitted mask or positioning support may help keep your head and neck still. The treatment beam is not felt, and each visit follows the same positioning process.

As treatment continues, the throat or mouth may feel sore, dry, or coated, and swallowing can become uncomfortable. Taste may change, saliva may become thick, and skin in the treated field can redden or peel. Tiredness is common. A dietitian, speech and swallowing specialist, dentist, or nurse may join your care team.

Follow the mouth-care plan and use rinses, pain relief, and saliva support only as advised. Keep drinking as directed and choose soft, moist foods if swallowing is sore; tell the team if eating or drinking becomes difficult. Do not smoke, vape, or use alcohol-based mouth products unless your clinicians specifically approve them.

Attend dental and nutrition appointments, practise swallowing exercises if prescribed, and protect neck skin from sun, friction, and unapproved creams. Take rest breaks while maintaining gentle activity that your team considers safe. Early reporting can prevent dehydration and loss of nutrition.

Contact your team promptly if pain prevents drinking, swallowing becomes suddenly worse, mouth sores bleed, or you have signs of dehydration such as very little urine, dizziness, or unusual weakness. Seek emergency help for trouble breathing, inability to handle saliva, sudden swelling, or a high temperature with marked illness.

Ask which parts of the throat and neck are treated, how swallowing will be assessed, and who to call about pain or nutrition. Ask about dental care, mouth rinses, exercises, feeding support if needed, skin products, and how other treatments may be coordinated.
