Symptoms

Signs and symptoms of osteosarcoma may include, among others:

• Swelling near a bone
• Bone or joint pain
• Bone injury or bone break for no clear reason

When to see a doctor

Make an appointment with your child's doctor if your child has any persistent signs and symptoms that worry you. Osteosarcoma symptoms are similar to many more-common conditions, such as sports injuries, so your doctor may investigate those causes first.
