What is a chordoma?
Chordomas are rare, slow-growing bone tumors. Less than 1% of all primary brain tumors are chordomas. This type of tumor is mostly found at the base of the skull, but sometimes appears in the lower spine. Chordomas can invade adjacent bone and put pressure on nearby nervous tissue.
