The role of Breast Care Nurses (BCNs) has been discussed since Breast Centres have been opened in Germany. This article introduces the concept of the Breast Care Nurses on a national and an international level in the context of Advanced Nursing Practice (ANP). Within a descriptive study, graduates of a German BCN-education programme were interrogated regarding their current work, their main activities as a BCN, about general conditions in their work environment, experienced barriers, and supporting factors. 122 questionnaires were evaluated. The return rate was 71% (n = 171). Results showed that 58.1% (n = 71) of the graduates were employed as a Breast Care Nurse, however only 28.1% (n = 20) in a full-time and 35.2% (n = 25) in a part-time position. This first German study about BCN-services showed a lack of basic work conditions, for example regarding a consultation room, access to literature, or templates for documentation. In the discussion part, the situation of the BCNs is reviewed in the German context and in relation to ANP concepts as well as regarding future demands for the position of a BCN.
