Information about Radiotherapy for Childhood Cancer

Radiotherapy is a type of treatment used to help control childhood cancers. Radiotherapy can be delivered at various points during a child’s course of treatment for cancer. It can also be given in differing schedules, where the number of treatment sessions varies, depending on factors such as the intention of the treatment, the type of cancer, and the age of a child. When a child is referred to a radiation oncologist for treatment, detailed information including an explanation of the child’s individual treatment course will be given by the team in the radiotherapy department.

This website aims to support patients through offering general information about radiotherapy in children for parents and caregivers, offering a broad understanding of the treatment and what to expect. For any further questions surrounding a child’s care, in particular for radiotherapy, please contact the radiation oncologist or the local radiotherapy department.
