Sarcomas are rare cancers that develop in the supporting tissues of the body. There are two main types: bone sarcomas and soft tissue sarcomas.
Bone sarcomas can develop in any of the bones of the body, but may also develop in the soft tissue near bones.
Soft tissue sarcomas can develop in muscle, fat, blood vessels, or any of the other tissues that support, surround and protect the organs of the body.
Ewing sarcoma most commonly occurs in the bone. This information should be read with our general information about bone cancer.
