Giant cell tumors are rare, aggressive, non-cancerous tumors. They usually develops near a joint at the end of the bone. Symptoms include a visible mass, bone fracture, swelling, and pain.
Treatments for giant cell tumors depend on many factors such as age, health, and the extent of the disease. Treatments may include amputation, bone grafting, bone reconstruction, or surgery. Tumors that can't be removed surgically can sometimes be destroyed with radiation therapy.
