ABSTRACT

Introduction: digital mammography allows us to increase the detection rate of high-risk breast lesions threefold. Objective: determine the incidence of high-risk breast lesions and their histomorphological characteristics. Material and methods: an observational, descriptive, retrospective, and longitudinal study was done at the Angeles Model Hospital from January 2015 to January 2020; through a review of the records of 388 Mexican women diagnosed with non-malignant breast lesions by surgical biopsy and/or percutaneous, 49 women were high-risk breast lesions, with a prevalence of 12%. Frequencies, proportions, minimum, mean, and maximum were used for data analysis. The software used was the statistical package Epi Info 7, a free-use program, and the SPSS version 25 program for Windows. Results: the distribution of cases by premalignant lesion was: flat epithelial atypia in two (4.1%) patients, radial scar in four (8.2%), atypical ductal hyperplasia in 12 (24.5%), atypical lobular hyperplasia in one (2.0%), papillomatosis in 16 (32.7%) and phyllodes tumor in 14 (28.6%). Conclusion: in our investigation, papillomatosis and phyllodes tumors were found with a very high frequency, leaving atypical ductal hyperplasia in third place.
