Hello. I'm Doctor Clayton Hess, founder of CureRays Radiation Medicine. Let me walk you through this page: Keep Childhood Cancer Away®. This page is written for parents. Childhood cancer is rare, and it is one of medicine's genuine success stories — around 85% of children diagnosed today are alive five years later, up from roughly 63% in the 1970s. Here is what you'll find on this page. If you have just been told. The main childhood cancers. Leukemia; Brain and CNS tumours; Lymphoma. Who is at risk. For the great majority, no cause is ever found. Childhood cancers are largely not linked to lifestyle or environment in the way adult cancers often are; Inherited predisposition accounts for roughly 10% — Li-Fraumeni, hereditary retinoblastoma, neurofibromatosis, Beckwith-Wiedemann, DICER1, Down syndrome (which raises leukemia risk); Previous cancer treatment — chemotherapy or radiation for an earlier cancer can rarely cause a second one years later. Here is what you can do next. Talk with us about radiation in children. If radiation has been proposed for your child, we will explain honestly what it protects, what it risks, and whether it can be reduced or avoided. Look for the button marked Contact CureRays.
