Biopsy, MRI, CT chest. An MRI will will tell you where the soft tissue sarcoma is, but will not definitively confirm the diagnosis. A ct of the chest will look for possible sarcoma spread. The lungs are the most likely place of spread. But a biopsy will establish or rule out the diagnosis of sarcoma and is the definitive test. It can be done with a needle in the office or through an incision in the operating room.
