Objective: To estimate the frequency of precursor intraepithelial lesions of cervical cancer in cytopathology laboratories belonging to the district network of the city of Bogotá D.C.

Materials and Methods: It was a descriptive study where the data corresponding to the year 2021 and the first semester of 2022 were taken, obtained by the information system of the Public Health Laboratory (LSP) of the network of laboratories of the district of Bogotá D.C., between January and December 2021, and January to June 2022.

Results: The total sample of cytology evaluated was from 1997, of which 189 corresponded to epithelial abnormalities, 1808 negative slides, 1602 with the presence of endocervical cells, 368 with the presence of microorganisms.

Conclusions: The most frequent positive diagnostic category was squamous cell atypia of undetermined significance in the group of women of 15-30 years-old; as well as in this group the frequency of non-neoplastic reactive changes and the presence of microorganisms, particularly Trichomona vaginalis.
