Breast cancer, chronic disease with organic, economic and psychosocial impact, is the primary neoplasm in females; both in developed and in developing countries, and it is a public health problem of global dimensions. The objective of this study is to describe the mortality rate trends for this disease in the state of Bahia, Brazil, from 1980 to 2006. Mortality and population data were collected in the Mortality Information System – SIM/DATASUS/ Ministry of Health and in IBGE/DATASUS, respectively. Mortality rates by age group, crude rates and standardized rates by age, adjusted for the numbers of deaths due undefined cause were calculated. Poisson regression models were used to analyze the  temporal trends, with evaluation of over dispersion. The results indicate that in Salvador, the crude rate had an average annual increase of 1.13% and the standardized rate, a reduction of 0.34%. The inspection of the curve demonstrates that there was an increase of 0.46% until 1997 and a reduction of 2.33% this year onwards. There was an increasing trend of 1.39% in the age group 20 to 49. Among women aged greater than or equal to 50 years there was a reduction of 2.73% from 1997. In the state of Bahia, the standardized mortality rates varied from 4.71 per 100,000 in 1980 to 7.92 per 100,000 in 2007. There was an increase of 2.70% in nonstandardized rate by age, adjusted for the number of deaths due to undefined cause. The standardized rate experienced an average annual increase of 1.52%. The rates adjusted by the number of deaths from undefined causes among women below and above 50 years had an increase of 3.02% and 2.45%, respectively. We conclude that there is a gradual increase in breast cancer mortality among women in the state of Bahia as a whole and a slight tendency to reduce in the city of Salvador. A longer period of observation will be necessary to verify the maintenance of these trends.
