Sarcoma is a type of cancer of the bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. The different types of sarcoma are named for where the cancer forms. For example, osteosarcoma is sarcoma that forms in the bone, and cardiac sarcoma is sarcoma that forms in the tissues of the heart.
