External beam radiotherapy

Radiation is directed at a defined area after preparation and planning. Effects depend on the treated volume and may involve skin, fatigue, mucous membranes or nearby organs. External beam sessions alone do not make a person radioactive. Follow the department's skin-product and local-care instructions. NCI

Preparation

Points to clarify with the care team before the procedure.

Use only products and treatments approved by the service on the treated area. Report all medicines and topical products.

Food and fluids

Needs depend on the irradiated area. Report painful swallowing, diarrhoea, vomiting or reduced intake so support can be adapted.

Mobility and rehabilitation

Adapt travel and activity to fatigue and disease-related limitations. Arrange transport to sessions.

Hygiene and activity

Ask for washing, skin protection, sex and travel instructions specific to the technique and treated area.
