It usually presents with pain or pain with movement in the area of the tumor, generally near a joint commonly at wrist, knee or hip joint. As it progresses, there is swelling, a mass, or fracture at the site of the tumor. There is weight loss. Please go to see your doctor when you have a persistent joint pain or bone pain.
