PURPOSE: The efficacy of screening mammography in reducing @entity0 mortality continues to be controversial. In addition, few data exist on the efficacy of screening mammography in @entity1 70  years of age or older. An organized screening mammogram program has existed in Saskatchewan since the mid-1990s. It offers mammography every 2  years to @entity1 >= 50  years of age. METHODS: We conducted a population-based case-control study to evaluate the efficacy of screening mammography, as practiced in Saskatchewan, Canada. Cases (n  =  501) were @entity1 who died of @entity0 during 1995-2008 and were at least 52  years of age at the time of their diagnosis. Controls (n  =  5,009) were matched to cases on birth year and duration of healthcare coverage prior to the cases' @entity0 diagnosis date. In cases and controls, receipt of screening mammography during the several years up to and including the date of the case's diagnosis of @entity0 was ascertained from the records of the screening program. RESULTS: Receipt of a screening mammogram in the preceding 2  years was more common among controls (53  %) than cases (37  %), OR 0.51 (95  % CI 0.42-0.62). A decreased risk was observed among @entity1 in all age groups, including those 70-79  years (OR 0.40; 95  % CI 0.27-0.60). CONCLUSION: Our findings suggest that receipt of screening mammography among @entity1 in Saskatchewan has been associated with a decreased risk of @entity204 from @entity0 .
