Osteosarcoma Staging

Osteosarcoma is described as either localized or metastatic.

Localized osteosarcoma

Localized osteosarcoma has not spread out of the bone where the cancer started. There may be one or more areas of cancer in the bone that can be removed during surgery.

Metastatic osteosarcoma

Metastatic osteosarcoma has spread from the bone in which the cancer began to other parts of the body. The cancer most often spreads to the lungs. It may also spread to other bones.
