Chondrosarcoma in children

Chondrosarcoma is a type of bone sarcoma that mostly occurs in adults.

It is very rare in children and young people, with cases making up about 10% of all chondrosarcomas.

Chondrosarcoma mostly affects the upper arm, thigh bone (femur), shoulder blades, ribs and pelvis.

Please note that this information is specific to chondrosarcoma that occurs in children.

Signs and symptoms

Symptoms of chondrosarcoma can vary depending on the size and location of your child’s tumour.

  • Bone pain, particularly occurring at night
  • A mass or swelling
  • Restricted movement in a joint

Symptoms can sometimes be confused with more common problems such as a sports injury or growing pains.


Your GP will examine your child and may arrange tests or X-rays. If your GP suspects that your child may have chondrosarcoma, they should refer your child to a specialist centre or hospital for further tests.

Your child will have a physical examination at the specialist centre or hospital. They may also be given a blood test to check their general health.

The doctor may conduct an X-ray of the bone that is in pain, which is often used to diagnose a bone tumour.

Your child may also have a number of tests, including a chest X-ray, a biopsy, an MRI or a CT scan. You can read more about scans and tests here.



Surgery is the main form of treatment for chondrosarcoma.

During surgery, the surgeon will remove the tumour and will aim to take out an area of normal tissue around it too. This is known as taking a margin. To achieve this margin of normal tissue, your child may receive limb-sparing surgery. The aim of this surgery is to preserve the limb where the tumour is rather than amputating it.

Limb-sparing surgery involves taking out the affected bone and replacing it with a bone graft (bone taken from another part of the body). Unfortunately, it’s not always possible to use limb-sparing surgery. Sometimes the cancer may spread from the bone to the nerves and blood vessels around it. If this happens the only way to treat the cancer may be to remove part of the limb known as a partial amputation. Your child may need to have all of their limb removed. This is called a full amputation.


Chemotherapy uses anti-cancer drugs to destroy cancer cells. It is sometimes used:

  • before surgery to reduce the size of the tumour so it can be operated on and removed (neo-adjuvant chemotherapy)
  • after surgery to kill off any local cancer cells which remain in the area of the tumour (adjuvant chemotherapy)


Radiotherapy uses high-energy radiation beams to destroy cancer cells. Chondrosarcoma is not usually sensitive to radiotherapy; however, this type of treatment may be used after surgery in some cases, if there is a risk that the cancer has spread to the surrounding soft tissue.

After treatment

Many children with chondrosarcoma are cured, although they may need to have surgery to lengthen their limb as they grow. Your child will have regular check-ups and X-rays as needed at an orthopaedic specialist centre.
