MATERIAL and METHODS: Turkish National Cancer Statistics, statistics of Turkey in GLOBOCAN 2018 and worldwide statistics country-by-country in GLOBOCAN 2018 was compared to reach a summary on this topic.

RESULTS: CNS tumors are 10^th comman in cancers in men with 5.2 for per 100.000. Also, in women group, CNS tumors? rate is 4.1 for per 100.000 and take the 9^th place of mostly seen first ten neoplasms. In general, the incidence of CNS cancers in women in our country is less than men as in the whole World. Turkish data between the years of 2010-2014 has shown that there is no significant difference for both sexes.

CONCLUSION: Although CNS cancers do not have high incidence rates, they have important mortality rates and, they consist one of a serious cause of death. Increase in the lifetime, exposure to environmental factors for the longer time, increasing usage of radioactive materials in our lives, easier access to healthcare systems and developing diagnosing possibilities may rise the incidence rates on CNS in the future. On the other hand, developing treatment modalities and post-treatment care strategies may reduce the mortality in these group of patients.
