A sarcoma is a rare kind of cancer. Sarcomas are different from the much more common carcinomas because they happen in a different kind of tissue. Sarcomas grow in connective tissue -- cells that connect or support other kinds of tissue in your body. These tumors are most common in the bones, muscles, tendons, cartilage, nerves, fat, and blood vessels of your arms and legs, but they can happen anywhere. Although there are more than 50 types of sarcoma, they can be grouped into two main kinds: soft tissue sarcoma and bone sarcoma, or osteosarcoma.
Osteosarcoma, less commonly, can occur in the back, the skull, and the ribs. In rare instances, it can occur in other bones of the body. Osteosarcoma is a very aggressive cancer; approximately 90% of all cases are highly malignant. There are several subtypes of osteosarcoma, and some are slightly less aggressive.
