Types of Bone Cancer
The most common type of bone cancer is osteosarcoma. Osteosarcoma develops in the new tissue of growing bones. Other types include:
- Ewing's sarcoma.
While chondrosarcoma begins in the cartilage, evidence suggests that Ewing's sarcoma begins in the immature nerve tissue of the bone marrow. Osteosarcoma and Ewing's sarcoma tend to occur more often in children and adolescents, while chondrosarcoma occurs more often in adults. Some people may also develop a rare type of bone cancer called malignant fibrous histiocytoma.

Causes and Risk FactorsAlthough no one knows the exact causes of bone cancer, research has shown that people with certain risk factors are more likely than others to develop the condition. A risk factor is anything that increases a person's chance of developing a disease.
Specific risk factors of bone cancer include:
- Being a child or young adult
- Previous radiation or chemotherapy
- History of Paget's disease
- Family history of bone cancer
- People with hereditary retinoblastoma.
