Introduction: Central nervous system tumors are rare; in 2015 they represented approximately 1.4% of new cancer diagnoses, causing 2.6% of deaths by cancer that year. Their prevalence decreases over time: between the ages of 0 to 14 years, these constitute the first cause of neoplasia, between 15 and 39 years they correspond to the third most frequent cause followed by breast and thyroid cancer, and in patients older than 40 years, it is among the rarest form of neoplasms. Given these data, knowledge about its incidence, mortality and epidemiology is necessary to develop and carry out health policies and diagnostic screening. In our country there are few reports, and those that do exist are based off of local population. Due to the limited epidemiological information, this work aims to characterize the epidemiology of brain tumors in Colombia over a period of 10 years, collected from population records in different cities of our country.
