Cohort and Case Control Analyses of Breast Cancer Mortality: BreastScreen Aotearoa 1999-2011

This major new study confirms that New Zealand’s organised breast screening programme, BreastScreen Aotearoa (BSA) is reducing deaths from breast cancer. The study concludes that for women who have ever been screened by BSA, the rate of death from breast cancer is reduced by a third, compared to women never screened by the programme. The findings of this study are in line with mortality studies of breast screening programmes internationally.
