Is Chordoma contagious?

Chordoma is not contagious and cannot be spread from person to person through touch, saliva, breath, or any other form of contact. Because chordoma is a rare type of cancer that arises from remnants of the notochord, it poses absolutely no risk of infection to family members, caregivers, or friends.

What exactly is chordoma?

Chordoma is a rare, slow-growing primary bone tumor that originates from the remnants of the notochord—an embryonic structure that usually disappears before birth. Chordoma typically develops along the spine, most commonly at the base of the skull (clivus) or the bottom of the spine (sacrum). It is a neoplastic process, meaning it is a result of uncontrolled cell growth, not an infectious disease caused by a virus or bacteria.

Why do some people worry about contagion?

The fear that chordoma might be contagious often stems from a lack of public awareness regarding rare cancers. Because chordoma is so uncommon—affecting approximately 1 in 1,000,000 people per year—the general public is rarely exposed to accurate information about it. Unlike infectious diseases, chordoma is not caused by pathogens, so there is no medical reason for isolation or social distancing when interacting with a patient.

Is there a genetic or environmental link?

Research into chordoma suggests that the condition is not hereditary in the traditional sense, though there are important biological factors involved:

• Genetic factors: Most cases are sporadic. However, a duplication of the brachyury gene (T gene) has been identified in some rare familial clusters.


• Environmental triggers: There is no evidence that environmental toxins, lifestyle choices, or infectious agents trigger the development of chordoma.


• Biological origin: The disease is fundamentally a developmental error occurring during embryogenesis.
