Response to "in defense of the international collaboration of breast registry activities (ICOBRA)"

The authors have provided in their response to our editorial a comprehensive history of the development of ICOBRA and how it evolved using what is regarded as “best practice” (rather than evidence-based best practice) from the experience of a number of countries and organizations. It has drawn from the analogies with the orthopedic experience, as have we in our article. It is apparent that much heartfelt endeavor has gone into the development of a hopefully successful international collaboration.
