Symptoms
In the early stages, synovial sarcoma does not always trigger symptoms. When the tumor progresses, people with this condition tend to have some signs that are similar to those of bursitis or arthritis. These include reduced mobility in legs or arms, pain, numbness, and swelling. Also, you might feel or see a lump in the affected area. When the tumor grows in the neck, it would change the voice or affect breathing. Shortness of breath can happen when the condition spreads to the lungs.[3]
