Where in the world is sinonasal cancer most common?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Sinonasal Cancer Answer length: short, citable
Quick answer

Sinonasal Cancer is not evenly distributed: the highest-burden regions are Europe (occupational clusters), North America and East Asia. In 2022 there were roughly 3–5% of all head and neck malignancies; incidence around 0.5–1 case per 100,000 per year in Western registries worldwide (no single global ASR — sinonasal sites are grouped within C30–C31 and are too rare for stable country rankings), with marked country-to-country variation driven by local exposures such as tobacco, areca nut, oncogenic viruses, ultraviolet radiation and occupational carcinogens.

In detail

The regional pattern matters clinically. A patient from Europe (occupational clusters) may present with a different risk-factor profile and a different stage distribution than a patient from a low-incidence country, which changes both the differential diagnosis and the pretreatment work-up.

All incidence figures on this site are age-standardised rates or absolute case counts from GLOBOCAN 2022 and its subsite analyses. They describe populations, not individual risk.

  • Europe (occupational clusters): Wood-dust exposure in furniture, cabinet-making and sawmill workers is a recognised cause of ethmoid sinus adenocarcinoma, with well-documented occupational cohorts in France, Italy, Germany and the Nordic countries.
  • North America: Occupational nickel, chromium, formaldehyde and wood-dust exposures plus HPV-associated sinonasal squamous cell carcinoma are the main recognised risk patterns.
  • East Asia: Sinonasal undifferentiated carcinoma and EBV-associated sinonasal lymphoepithelial lesions are reported more often in EBV-endemic Asian populations, though all types remain rare.
  • North Africa & the Middle East: Nasopharyngeal carcinoma rather than sinonasal cancer dominates this region; distinguishing the two requires endoscopy and MRI because symptoms overlap.
  • No true endemic region: Unlike NPC or oral cavity cancer, sinonasal cancer shows no strong population-level geographic hotspot; exposure history matters more than nationality.
