Context: Primary brain tumor (PBT) causes poor prognosis and significant complications, which includemovement problems such as balance disorders, failed return to work, and daily life activities. Objectives: The aim of the present study is to estimate the prevalence of PBT in Iran, using a meta-analysis method. Methods: This meta-analysis study was conducted in Iran in 2023 and articles published until the beginning of 2023 were included in the study, using the English keywords of brain cancer, brain tumor, tumor prevalence, prevalence, cancer, nervous system cancer, and their Persian equivalents. Data analysis was carried out, using CMA software. Results: After the initial search, 890 articles on BT were found, and 21 eligible articles were included in the meta-analysis. Also, the prevalence of brain cancer is 4% (95%CI: 3.3 - 4.8) in men and 2.9% (95%CI: 2.3 - 3.6) in women. Conclusions: According to the result, the BT incidence rate is 4% for males and 2.9% for females. Therefore, it is necessary to take necessary preventive measures in this regard.
