How is diagnosis of a chordoma confirmed?

ANSWER

A biopsy is the only test that can confirm you have a chordoma. Your doctor will use a needle to take a small sample of cells from the tumor. A specialist will look at the cells under a microscope to see what kind of tumor you have.

Your doctor might also do a blood test, a CT scan of your lungs, or a bone scan to see if the tumor has spread.
