Soft tissues connect, support, and surround other body parts and organs.
Soft tissue sarcomas are rare in children and adolescents. If a patient has symptoms of a soft tissue sarcoma, the doctor may order x-rays and other tests. The doctor may also cut out a small piece of tissue and have it looked at under the microscope to see if there are any cancer cells. This is called a biopsy. There are many different kinds of soft tissue sarcoma, depending on the soft tissue where the cancer begins.
