Hello. I'm Doctor Clayton Hess, founder of CureRays Radiation Medicine. Let me walk you through this page: Keep Bone Cancer Away®. Primary bone cancer is rare — about 3,770 new cases a year in the United States — and it is one of the few cancers that peaks in teenagers. Nearly a quarter of cases occur before age 20. Here is what you'll find on this page. Where you are treated matters more than almost anything. The single most important thing on this page: sarcomas should be diagnosed and treated at a specialist sarcoma centre, and the biopsy should be planned by the surgeon who will do the operation. Who is at risk. Age — osteosarcoma and Ewing sarcoma peak in teenagers and young adults, during the growth spurt; chondrosarcoma occurs in older adults; Previous radiation therapy to the area, usually many years earlier; Inherited conditions — hereditary retinoblastoma (RB1), Li-Fraumeni syndrome (TP53), Rothmund-Thomson syndrome, and multiple hereditary exostoses or enchondromatosis (which predispose to chondrosarcoma). Here is what you can do next. Go deeper on bone cancer. Read the full plain-language guide, or ask our team where radiation fits for your tumour type.
