Soft-tissue tumors are typically painless, firm masses. While osseous tumors often present with pain. A number of diagnostic tests may be required to accurately identify a sarcoma, including blood tests, x-rays, CT scan, MRI, bone scan, and PET scan. Biopsy may also be indicated.
Fortunately, benign (non-cancerous) tumors are far more common than sarcomas. Depending upon tumor type, treatments range from observation to surgery, chemotherapy, and radiation therapy.
