Bone cancer - a malignant tumor that may develop throughout the bone system. Despite the fact that malignant bone tumors represent the second most common form of solid (dense, compact growing) tumors arising in children and young people aged between 10 and 20 years, this is a rare disease: a little more than 5 cases per million children to meet each year in the United States.

Any tumor that arises in the bone and connective tissue of the skeleton is called primary bone cancer. Second place on the incidence of primary bone cancers occurring in children and adolescents, take osteogenic sarcoma, which usually begins in the brain of the bone, and Ewing sarcoma, usually originating from bone marrow. Less common malignant tumors include chondrosarcoma and non-Hodgkin’s lymphoma bone.
