Average age at diagnosis is 15. Boys and girls are just as likely to develop this tumor until the late teens, after which it occurs more often in boys.

However, it can occur in any bone. Symptoms The first symptom is usually bone pain near a joint. This symptom may be overlooked, especially in young people, because of other more common causes of joint pain. Other symptoms may include any of the following:Bone fracture (may occur after a routine movement) Limitation of motion Limping (if the tumor is in the leg) Pain when lifting (if the tumor is in the arm) Tenderness, swelling, or redness at the site of the tumor Exams and Tests The health care provider will perform a physical exam and ask about the medical history and symptoms.Tests that may be done include:Biopsy (at time of surgery for diagnosis) BiopsyA biopsy is the removal of a small piece of tissue for laboratory examination.Read Article Now Book Mark Article Blood tests Bone scan to see if the cancer has spread to other bones Bone scanA bone scan is an imaging test used to diagnose bone diseases and find out how severe they are.ImageRead Article Now Book Mark Article CT scan of the chest to see if the cancer has spread to the lungs CT scanA computed tomography (CT) scan is an imaging method that uses x-rays to create pictures of cross-sections of the body.
