Osteosarcoma is a cancer of the bone that is most common in adolescents. Osteosarcoma usually starts in osteoblasts, which are a type of bone cell that becomes new bone tissue and usually forms in the ends of the long bones of the body, which include bones of the arms and legs. It affects more males than females.
Malignant fibrous histiocytoma (MFH) of bone is a rare tumor of the bone. It is treated like osteosarcoma.
