title: [Increase in breast cancer mortality in Southern Brazil from 1980 to 2002].
abstract: Breast cancer is the most prevalent form of cancer in the world. Breast cancer mortality rates are high in Brazil and show striking variations between geographic regions. A time-trend ecological study was performed in Southern Brazil from 1980 to 2002. Data were collected from the Mortality Information System (Ministry of Health) to assess age-standardized mortality rates. Linear regression for mortality time-trend analysis and multiple regression for mortality differences among three States were calculated. The highest mean mortality rate (14.45) was observed in Rio Grande do Sul, significantly greater (p < 0.001) than in Santa Catarina (8.93) and Paraná (9.95). An annual increase of 0.47 in the mortality rate was observed in the three States of Southern Brazil. According to these results, the South of Brazil and especially the State of Rio Grande do Sul showed a significant upward trend in breast cancer mortality. Continued efforts are needed to help explain these numbers and reverse the present situation.
