Living with Chordoma

A rare, slow-growing cancer that can occur anywhere along the spine, from the skull base to the tailbone.

Understanding Chordoma

Chordoma is a rare cancerous tumor that can occur anywhere along the spine, from the base of the skull to the tailbone.

Chordomas grow slowly into nearby bone and soft tissue and often come back after treatment. In about 40 percent of cases they spread to other areas, such as the lungs. About half occur at the base of the spine, and a third at the base of the skull. They typically occur between ages 40 and 70, and about 5 percent are found in children. Males are affected about twice as often as females.

Signs & symptoms

Symptoms depend on where the tumor is. GARD says a chordoma may cause:

  • Pain, weakness, or numbness in the back, arms, or legs
  • Double vision (skull base tumors)
  • Headaches (skull base tumors)
  • A lump you can feel (tailbone tumors)
  • Bladder or bowel problems (tailbone tumors)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, cancer specialists, genetic specialists and hormone specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Chordoma Foundation and Pituitary Network Association may keep lists of experts for this condition.
