Frequency of Mammography in Brazilian Regions

Introdução

Mammography is the routine screening exam for detecting breast cancer, and it is essential due to the high mortality rate associated with this neoplasm among Brazilian women. The exam plays a fundamental role in early detection, increasing the chances of successful treatment. It is recommended that women aged 50 to 69 undergo mammography every two years, even in the absence of symptoms, to identify changes that may indicate cancer.

Objetivo

The objective of this study is to present population data related to the performance of mammography in various parts of Brazil, in addition to analyzing the data obtained regarding adherence and continuity of follow-up.

Métodos

This is an observational, descriptive, and cross-sectional epidemiological study that aims to analyze the absolute numbers of mammograms performed in the states of Brazil between 2018 and 2024. A search was conducted in the Cancer Information System (SISCAN) within DATASUS. Women who had at least one mammogram between 2018 and 2024 were included.

Resultados

During the analyzed period, Brazil revealed marked regional disparities in the performance of mammograms in women, with a total of 18,911,751 exams performed. In 2023, there was a peak of 3,545,303 mammograms, the highest annual number of the period, while in 2020, 1,864,892 exams were performed. São Paulo led with 2,981,842 exams, followed by Minas Gerais (2,541,116) and Paraná (1,919,683). In contrast, Amapá recorded 15,798 exams, followed by Roraima (24,628) and Tocantins (63,230), reflecting significant regional inequalities. The Southern region performed 4,262,308 exams, the Southeast 7,048,048, while the Northern region recorded only 778,063. These disparities highlight critical challenges in accessing breast cancer screening in Brazil. The Southeast and South regions demonstrate significantly higher coverage, while the North and Northeast regions show substantially lower figures, reflecting structural inequalities in the healthcare system.

Conclusões

Therefore, we conclude that the Brazilian regions with the highest levels of deprivation are the ones with the lowest adherence to the exam. While the Southeast and South regions reflect broader and more consistent coverage, the North and Northeast regions show significantly lower numbers of exams performed. To reverse this scenario, it is essential to implement public policies that promote easier access to the exam and encourage women to seek preventive measures.
