Abstract

Objetive: To analyze breast cancer screening monitoring indicators in the female population assisted by the Brazilian Unified Health System, from 2018 to 2019. Methods: Descriptive study based on the Cancer Information System (Siscan). Screening indicators were calculated through the deterministic linkage of the mammography and histopathological databases. Results: In 2018, 807,430 women, aged 50 to 69 years were screened for breast cancer. Of these, 91% had a benign result, 1.8% probably benign, 6.7% inconclusive results and 0.5% suggestive of cancer. The positive mammography rate was 9.0%. An indication for biopsy was estimated for 1.6% of the women, a malignant result for 33.9% of them and a cancer confirmation rate of 5.4 per 1,000 women. Conclusion: A high loss of follow-up of benign lesions was identified. The rate of positive mammograms was lower than the international parameter, but the cancer detection rate was adequate and the percentage of inconclusive mammograms acceptable.
