RODRIGUES, Anselmo Duarte and BUSTAMANTE-TEIXEIRA, Maria Teresa. Breast cancer and cervical cancer mortality trends in a medium-sized city in Southern Brazil, 1980-2006. Cad. Saúde Pública [online]. 2011, vol.27, n.2, pp.241-248. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2011000200005.
The aim of this study was to analyze mortality trends from breast cancer and uterine cervical cancer in Juiz de Fora, Minas Gerais State, Brazil. The mortality time series from the Mortality Information System of the Brazilian Ministry of Health was used. Age-related specific mortality rates were calculated and standardized against the world population. Polynomial regression models were applied. Breast cancer was the main cause of cancer-related death for women in Juiz de Fora. Trend analysis using the polynomial regression model showed a decrease in mortality due to uterine cervical cancer (p = 0.001) and an increase in mortality due to breast cancer (p = 0.035) over the course of the time series. The trends in mortality due to breast cancer and cervical cancer in Juiz de Fora suggest an ongoing epidemiological transition, with significant mortality due to breast cancer and persistently high cervical cancer rates.
