<div>Background: The German Mammography Screening</div><div>Program (German MSP) is population-based and intended</div><div>for women aged 50–69 years (approximately 10.5</div><div>million). The program started in 2005 and was implemented</div><div>within 5 years. This article describes the implementation,</div><div>structure, and screening process, and presents</div><div>the results of initial examinations for the prevalence</div><div>phase. Methods: Data were collected annually</div><div>from invitation centers (invitation, attendance), screening</div><div>units (performance, outcomes), and cancer registries</div><div>(incidence). Results: In 2009, 92% of all annually eligible</div><div>women were invited; 50% of the annually eligible population</div><div>participated. The total cancer detection rate in the</div><div>period of 2005–2009 was 8.1/1,000; the corresponding recall</div><div>rate was 5.9%. 19.6% of detected cancers were ductal</div><div>carcinoma in situ; 76.7% of invasive cancers were ≤ 20</div><div>mm in size, 30.2% were ≤ 10 mm, and 75.3% were nodenegative.</div><div>During the implementation period, incidence</div><div>increased by 37 and 56% in the old and new federal</div><div>states, respectively. Incidence rates decreased following</div><div>the prevalence phase. Conclusion: The German MSP</div><div>was successfully implemented. The results of the prevalence</div><div>phase meet the target values of the European</div><div>guidelines. Proper functioning of the program is also</div><div>verified by its effects on breast cancer incidence. To</div><div>draw reliable conclusions regarding the long-term effects</div><div>of the program, results from the routine screening</div><div>rounds have to be awaited.</div>
