A tumor that occurs in the bones and soft tissues.
Sarcoma is an uncommon type of cancer. In most cases, it's not clear what causes sarcoma. Family history and exposure to chemicals or radiation may increase risk.
Bones and connective tissue, such as fat and muscle, are affected. Symptoms depend on tumor type and location. They may include a noticeable lump or pain.
Treatment may include surgery, radiation, and chemotherapy.
