When is radiotherapy recommended for nasal and sinus cancer?

The nasal cavity and sinuses sit close to the eyes, brain, nerves, and other delicate structures. Specialists use scans, examination findings, tumour location, and the planned operation to decide whether radiation can reduce the chance of tumour cells remaining in the treated region.

Radiotherapy may be given after surgery when the pathology shows features that raise concern for local return. In some situations it is combined with medicines or used as the main local treatment. The plan is shaped to protect nearby organs as much as possible while treating the identified target.

Bring details of previous surgery, dental work, eye problems, medicines, and any changes in smell, vision, hearing, nasal blockage, or facial sensation. Ask whether an ear, nose and throat specialist, dental professional, dietitian, or eye specialist should be involved before treatment begins.

Radiation can irritate the lining of the nose, mouth, or throat and may affect saliva, skin, or energy. Ask how to clean the treated area, manage dryness, protect the skin, and maintain food and fluid intake. Report symptoms early so supportive care can start promptly.

Contact the treatment team urgently for sudden vision changes, severe eye pain, new facial weakness, confusion, heavy bleeding, breathing difficulty, or inability to drink. These symptoms need prompt clinical assessment rather than waiting for the next scheduled visit.

Ask what the radiation is intended to achieve, whether surgery or medicines come before it, which nearby structures are being protected, how nasal and oral symptoms will be managed, and when follow-up scans or examinations are planned.
