Mortalidade por câncer de mama nos municípios de grande porte do Rio Grande do Sul (RS)

Abstract

Breast cancer is the leading cause of female death in Brazil, except in the North region. Socioeconomic statuses impact disease outcomes. Screening through mammograms is effective; however, unequal access to healthcare services affects diagnosis and treatment. Objective: This study aimed to analyze breast cancer mortality in women aged 50 to 69 in municipalities with more than 100,000 inhabitants in Rio Grande do Sul from 2009 to 2019 and its relationship with socioeconomic indicators. Methods: This is an ecological study on female breast cancer mortality rates in nineteen cities in RS. Mortality population data were obtained through Health Information Systems provided by DATASUS. To assess the relationship between sociodemographic indicators and mortality rates, the Pearson correlation coefficient was calculated, and analysis of variance was performed using the "F" test. The significance level adopted for the interpretation of all tests was p <0.05. Results: The cities with the highest mortality rates were Rio Grande, Uruguaiana, and Passo Fundo, while the lowest rates were observed in Erechim, Viamão, and Gravataí. The results revealed variations in rates, with Gravataí and Passo Fundo experiencing significant changes. Conclusion: There was no clear correlation between socioeconomic indicators and mortality rates, indicating the influence of other factors. Studies like this assist in formulating health policies to reduce breast cancer mortality.
