Surgery and radiation therapy are the common forms of treatment. Chordomas at the base of the skull can be difficult to remove. Surgical resection may be possible if the tumor is located in the spine.

Please speak with your health care provider for more information about your tumor type, biomarkers, and treatment options, including clinical trials.
