Bone cancer

Also called Primary bone cancer, Osteosarcoma, Ewing sarcoma, or Chondrosarcoma

Primary bone cancer starts in the bone itself. It is rare and is different from cancer that spreads to the bones from elsewhere, which is much more common. The main types are osteosarcoma and Ewing sarcoma, which mostly affect children and young adults, and chondrosarcoma, which is more common in older adults.

What it is

The first sign is usually bone pain that gets worse over time and is often worse at night. It can be mistaken for a sports injury or growing pains.

Treatment is planned by specialist sarcoma teams and usually combines surgery with chemotherapy or radiotherapy. Limbs can often be saved.

Common signs

  • Persistent bone pain, often worse at night
  • Swelling or a lump over a bone
  • A bone that breaks after a minor injury
  • Reduced movement in a nearby joint

How it is usually diagnosed

  • X-ray
  • MRI and CT scans
  • Biopsy at a specialist centre
  • Bone scan or PET-CT to check for spread

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • X-ray, MRI and CT reports
  • Biopsy and pathology reports
  • Treatment plans and operation notes
  • Follow-up scan schedule

Questions to ask your doctor

  • What type of bone cancer is it, and has it spread?
  • What will treatment involve and how long will it take?
  • What support is there for school, work and fertility?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden severe pain and inability to use a limb, which may be a fracture
