These tumors most commonly start in legs. Alveolar soft-part sarcoma is a rare cancer that mostly affects young adults.It's most common in people between the ages of 20 and 60, but can occur in people of any age, even in infants. Adult fibrosarcoma usually affects fibrous tissue in the legs, arms, or trunk.Some are quite rare, and not all are listed here: Types of soft tissue sarcomasÄifferent types of soft tissue sarcomas.

Sarcomas that most often start in bones, such as osteosarcomas, and sarcomas that are most often seen in children, such as the Ewing Family of Tumors and Rhabdomyosarcoma, are not covered here. They can also be found in the trunk, head and neck area, internal organs, and the area in back of the abdominal (belly) cavity (known as the retroperitoneum). They can be found in any part of the body.

Soft tissue sarcomas can develop in soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues. Bone and soft tissue sarcomas are the main types of sarcoma. A sarcoma is a type of cancer that starts in tissues like bone or muscle. When the word sarcoma is part of the name of a disease, it means the tumor is malignant (cancer). These are called intermediate soft tissue tumors. Some soft tissue tumors behave in ways between a cancer and a non-cancer. These tumors can't spread to other parts of the body. The word benign means they're not cancer. Many benign tumors are found in soft tissues. There are many types of soft tissue tumors, and not all of them are cancerous. To learn more about how cancers start and spread, see What Is Cancer? Cells in nearly any part of the body can become cancer and can spread to other areas. Cancer starts when cells start to grow out of control.
