What is Sarcoma?

Sarcoma is the name given to a broad category of tumors-approximately one percent of adult cancers and 20 percent of all childhood cancers. This class of tumor occurs in connective tissue such as bones, joints, nerves, muscles and blood vessels. Though no one knows for sure, possible causes of these tumors may be exposure to certain chemicals and radiation. As is true of most cancers, sarcomas are locally invasive and often spread to distant organs and tissue. These tumors are detected by physical examination, xray, CT, and MRI, but definitive diagnosis is by surgical biopsy. Treatment options are resection locally, chemotherapy, and radiation therapy.
