Short answer · Medically reviewed summary · Last updated: 2026-05-08
Chordoma is a rare type of cancer that arises from remnants of the notochord, with an estimated annual incidence of approximately 0.08 to 0.5 per 100,000 people. While it is considered a rare disease, the exact prevalence is difficult to determine due to its slow-growing nature and historical challenges in diagnostic reporting. How common is Chordoma in the general population? Chordoma is classified as a rare disease.
What is the prevalence of Chordoma?
Prevalence of Chordoma: how many people are affected worldwide, differences by sex and region, with sources.
Chordoma is a rare type of cancer that arises from remnants of the notochord, with an estimated annual incidence of approximately 0.08 to 0.5 per 100,000 people. While it is considered a rare disease, the exact prevalence is difficult to determine due to its slow-growing nature and historical challenges in diagnostic reporting.
How common is Chordoma in the general population?
Chordoma is classified as a rare disease. Because it often grows very slowly and may remain asymptomatic for years, many cases are likely underdiagnosed or reported only upon discovery during imaging for unrelated issues. Current estimates suggest that roughly one in every million people is diagnosed with Chordoma each year, though these figures vary by region and reporting standards.
What is the typical age and gender distribution for Chordoma?
Chordoma can occur at any age, but it most frequently presents in adults between the ages of 40 and 70. While it is rare in the pediatric population, it does occur and often follows a more aggressive clinical course in younger patients. Regarding gender, Chordoma demonstrates a slight predilection for males, who are affected at a ratio of approximately 1.5 to 2 times that of females.
What factors influence the epidemiology of Chordoma?
Epidemiological data for Chordoma reveals specific patterns regarding tumor location and demographic variables:
- Location: Approximately 50% of Chordoma cases occur in the sacrum, 35% in the base of the skull, and 15% in the mobile spine.
- Gender: Males are consistently reported to have a higher incidence rate across most global registries.
- Community Insight: At DiseaseMaps.org, 34 individuals living with Chordoma have joined our community, providing a real-world perspective that complements clinical data by highlighting the lived experience of diagnosis and long-term management.
Why is accurate prevalence data for Chordoma difficult to obtain?
The primary challenge in establishing the true prevalence of Chordoma is its rarity and the lack of comprehensive national tumor registries in many countries. Misdiagnosis is also a factor, as Chordoma can be mistaken for other bone or soft tissue tumors on initial imaging, leading to delays in definitive histological confirmation.
Next steps
