- Epidemiology
- The annual global age-standardized incidence of primary
malignant brain tumors is ~3.7 per 100,000 for males and 2.6 per
100,000 for females2, 3. Rates appear to be higher more developed
countries (males, 5.8 and females, 4.1 per 100,000) than in less
developed countries (males 3.0 and females 2.1 per 100,000).
