Synovial sarcoma is a slow-growing tumor. Because it grows slowly, a person may not have or notice symptoms for some time, resulting in a delay in diagnosis. The most common symptoms of are swelling or a mass that may be tender or painful. The tumor may limit range of motion or press against nerves and cause numbness. The symptoms of synovial sarcoma can be mistaken for those of inflammation of the joints (arthritis) or other non-cancerous conditions that cause inflammation such as bursitis and synovitis.
