title: Inequalities associated with lack of mammography in Teresina-Piauí-Brazil, 2010-2011.
abstract: BACKGROUND
  Randomized studies have shown that screening for breast cancer with mammography reduces the breast cancer mortality. However there are signs of a great inequality in access to mammography in Brazil.
  
  
  OBJECTIVE
  To analyze the percentage of women who did not undergo mammography according to socioeconomic and demographic variables in women aged from 40 to 69 years in Teresina, Piauí State, Brazil.
  
  
  METHODS
  This was a cross-sectional population-based study in women aged 40-69 years in Teresina-Piauí in 2010/2011. The sampling was randomly conducted in five stages. The data were processed by SPSS 19.0 and it was performed univariate and multivariate analysis.
  
  
  RESULTS
  Among 433 women who answered the questionnaire, 75,3% had a mammography and 17,2% of these women had not a mammography over the last two years. The lack of breast cancer screening was associated with non-white skin color (p = 0,030), never being married (p = 0,041), low levels of education (p = 0,010), low family income (p < 0,001), smoking (p = 0,006), having no private health insurance (p < 0,001). The Unified National Health System (SUS) performed 56,3% of reported mammograms.
  
  
  CONCLUSIONS
  About 24.7% of women in the sample never had a mammography. According to the findings, the lack of breast cancer screening is associated with social and racial inequalities.
