Does radiotherapy treat salivary gland cancer?

The treatment uses carefully planned radiation to damage cancer cells in a defined area. A specialist may recommend it after an operation if the tumour had features that raise concern about cancer cells remaining nearby, or if the tumour could not be fully removed. It may also be considered for a tumour that has returned in the salivary gland region. The plan depends on the gland involved, tumour type, size, position, nearby nerves, and whether lymph nodes or other areas are affected.

Radiotherapy is not automatically needed for every salivary gland cancer. It can affect nearby tissues, including the mouth, throat, skin, and the glands that make saliva. Your team can explain which effects are likely and how they will protect healthy tissue.

Ask the head-and-neck cancer team to review the pathology report and scans with you. Before treatment, discuss whether surgery, radiotherapy, or a combination is being recommended and what each option is intended to achieve. Tell the team about dental problems, dry mouth, medicines, and previous radiation treatment. A dental assessment may be arranged because mouth care matters during treatment.

During a course of radiotherapy, follow the skin and mouth-care instructions, keep appointments, and report difficulty eating, drinking, or swallowing early. Ask about nutrition support if meals become difficult.

Contact your treatment team promptly if you cannot keep fluids down, swallowing becomes harder, mouth sores stop you eating, or pain is not controlled by the agreed plan. Seek urgent help for trouble breathing, sudden facial weakness, confusion, or heavy bleeding. New or worsening swelling around the face or neck also deserves prompt assessment.

Which salivary gland and tumour features shape my treatment plan? Is radiotherapy intended after surgery, instead of surgery, or for a recurrence? What areas will be treated, and how might this affect saliva, swallowing, hearing, teeth, or facial movement? What support is available for eating and mouth care?
