The Cooperative Association of the German Mammography Screening Programme (Kooperationsgemeinschaft Mammographie, or KoopG for short) was founded in 2003 as a non-profit joint venture of the National Association of Statutory Health Insurance Funds and the National Association of Statutory Health Insurance Physicians (see Legal Basis and Specifications).
It consists of the German Mammography Screening Office in Berlin and five Reference Centres (RC), located in Berlin (RC Berlin), Gießen (RC SouthWest), Münster (RC Münster), Munich (RC Munich), and Oldenburg (RC North). The Cooperative Association is responsible for quality assurance and training in the programme, as well as evaluations concerning the quality of structures, processes and results.
