When is radiotherapy recommended for salivary gland cancer?

The decision depends on the gland involved, the cancer type, its size and location, whether it has reached nearby nerves or lymph nodes, and what the operation removed. Treatment may target the original gland area and nearby tissues. A specialist plans the field to protect structures such as the eyes, jaw, swallowing muscles and spinal cord as far as possible. Radiotherapy can be given after an operation to reduce the chance of local return, or as the main local treatment when an operation would cause unacceptable harm. It can also shrink cancer or reduce pain, bleeding, pressure or nerve-related symptoms when cure-focused treatment is not appropriate.

Ask the treating team to explain the pathology report, including the tumour grade, surgical margins, nerve involvement and lymph-node findings. These details help show why radiotherapy is being proposed. Discuss whether imaging is needed before planning, how the treatment area will be marked, and how dental, swallowing or facial-nerve concerns will be managed. Report medicines, previous radiotherapy and any dental problems before treatment begins. During treatment, follow the skin and mouth-care instructions supplied by the radiotherapy team.

Contact the oncology team promptly for worsening facial swelling, new weakness of the face, trouble breathing or swallowing, uncontrolled bleeding, or severe dehydration from difficulty drinking. Seek urgent medical help for sudden breathing difficulty, confusion or heavy bleeding. New or changing symptoms should be assessed because they may reflect the cancer, treatment effects or another condition; they do not by themselves establish the cause.

Why is radiotherapy recommended in my case, and what area will it cover? Is the aim to reduce local recurrence, control existing cancer or relieve symptoms? How might treatment affect saliva, swallowing, hearing, teeth, skin and facial movement? What alternatives fit my pathology and overall health?
