What is soft tissue sarcoma?
Soft tissue sarcomas may develop in any tissue that connects, supports or surrounds other structures and organs in the body. Some examples of where soft tissues sarcomas can develop are muscles, fascia (the tough membrane that surrounds muscles), tendons, fat, blood vessels, nerves and synovial tissues (connective tissue that makes up the membranes surrounding joints).
Soft tissue sarcoma incidence
Soft tissue sarcomas are rare in adults, accounting for less than 1 percent of all new cases of cancer.
Sarcomas can be found almost anywhere in the body. According to the National Cancer Institute, about 43 percent of soft tissue sarcoma cases occur in the extremities (arms and legs), 34 percent form in or around the internal organs, 10 percent occur in the trunk (back and chest) and 13 percent occur in other locations.
The American Cancer Society reports that about 11,930 new cases of soft tissue sarcoma will be diagnosed in 2015 (6,610 cases in males and 5,320 cases in females).
