Bone Sarcomas Fund

Bone sarcomas are rare cancers that originate in the bones, accounting for less than 1% of all diagnosed cancers. The three main types are osteosarcoma, Ewing sarcoma, and chondrosarcoma. Symptoms typically include persistent bone pain, swelling, and sometimes fever or pathologic fractures. The severity varies, with those caught early and contained to one tumor having a 70-80% survival rate, while metastatic disease drops to 20-30% survival. Osteosarcoma and Ewing sarcoma primarily affect children and young adults, with a median age of onset in the teenage years, while chondrosarcoma usually occurs in adults aged 40-75.
