Description

A sarcoma is a type of cancer that develops from certain tissues, like bone or muscle. Bone and soft tissue sarcomas are the main types of sarcoma. Soft tissue sarcomas can develop from soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues. They can be found in any part of the body. Most of them develop in the arms or legs. They can also be found in the trunk, head and neck area, internal organs, and the area in back of the abdominal cavity (known as the retroperitoneum). Sarcomas are not common tumors, and most cancers are the type of tumors called carcinomas. Sarcomas that most often start in bones, such as osteosarcomas, and sarcomas that more often occur in children, such as the Ewing Family of Tumors and Rhabdomyosarcoma, are discussed separately. Adult fibrosarcoma Alveolar soft-part sarcoma Angiosarcoma (includes hemangiosarcoma and lymphangiosarcoma) Clear cell sarcoma Desmoplastic small round cell tumor Epithelioid sarcoma painful swallowing, and headache.
