[Breast cancer: suspicious findings on mastography associated with the histopathological result].

Background: Breast cancer occupies first place in mortality by neoplasms in women in Mexico; mammography screening (MS) interpreted by BI-RADS (Breast Imaging-Reporting and Data System), allows suspicion of malignancy, which will be confirmed when having the histopathological result (HPR).

Objective: o evaluate whether suspicious findings for breast cancer in MS are associated with malignant HPR in women aged ≥ 40 years.

Material and methods: Observational, analytical, cross-sectional, prolective study. Patients aged ≥ 40 years, with MS with BI-RADS 4a, 4b, 4c and 5, and RHP of sample obtained by Trucut, excisional or ultrasound-guided biopsy were analyzed. Sociodemographic, anthropometric, clinical variables, BI-RADS classification and HPR variables were recorded.

Results: 148 patients were included, median age 53 years; these were stratified into BI-RADS 4a, BI-RADS 4b, BI-RADS 4c and BI-RADS 5. Suspicious findings of malignancy due to MS were associated with HPR. MS BI-RADS 4c, palpable lesion and late menopause were identified as risk factors for malignant HPR; as well as MS BI-RADS 5 and palpable lesión.

Conclusion: MS with suspicious findings of malignancy is associated with the malignant HPR obtained by biopsy.
