BONE SARCOMA OVERVIEW
There are several types of bone cancer.
Osteosarcoma is the most common bone cancer. It starts in bone cells that make new bone tissue. It usually forms at the end of long bones, such as the leg bones, but can form in any bone. It is most common in teenagers and in adults older than 65 years. Malignant fibrous histiocytoma of bone is a very rare bone cancer. It is treated like osteosarcoma.
Ewing sarcoma includes several types of bone tumors. Ewing sarcoma tumors usually form in the hip bones, the ribs, or in the middle of long bones. The disease occurs most often in teenagers and young adults. Ewing tumors are most common in bone but can also form in soft tissue.
Having past treatment with radiation can increase the risk of osteosarcoma. A small number of bone cancers are caused by inherited conditions. Signs and symptoms of bone tumors include a lump, swelling, and pain.
