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, such as osteosarcoma, can develop in any of the bones of the body. They may also develop in the soft tissue near bones.
Soft tissue sarcomas can develop in muscle, fat, blood vessels, and any of the other tissues that support, surround and protect the organs of the body.
