Incidencia de tumores benignos de mama en pacientes comprendidas entre 18 a 45 años de edad. Consulta externa mastología - Hospital Teodoro Maldonado Carbo. Octubre 2018 - marzo 2019.

Abstract

Background: Benign breast disease has become more common as the use of mammography and ultrasound has increased, and therefore new epidemiological estimates of its frequency are imperative as these lesions are a risk factor for neoplasia. Objective: To establish the incidence of benign breast lesion in the Mastology outpatient clinic of the Teodoro Maldonado Carbo hospital in women aged 18 to 45 treated between October 2018 and March 2019 Methodology: a case report was carried out that randomly included 70 cases of patients with benign breast lesions treated at the institution. For the statistical analysis, relative and absolute frequencies, rates, average and standard deviation were calculated. Results: The prevalence of benign lesions was 38.1%. The incidence of 2.24 x 1000 cases in 2018 and rose to 4.71 x 1000 cases for 2019. 2 types of benign lesions were reported, fibrocystic changes (34.5%) and benign neoplasms that were the most frequent (65.5%). The mean age of the sample was 34.1 ± 8 years. The most important risk factors were xanthine intake (77.1%), family history of breast cancer (27.1%), and use of contraceptives (25.7%). In 95.7% of the cases ultrasound was performed for diagnosis. Conclusions: The incidence of benign breast lesions is low, with a lower prevalence than that of malignant lesions, a consequence of the status of this hospital as a reference.
