The second plenary of the European Commission Initiative on Breast Cancer (ECIBC) took place from the 9 to the 11 December 2015 in Baveno, Italy. The purpose of the ECIBC Plenaries is to inform stakeholders on the activities of the ECIBC while at the same time seeking their feedback. The ECIBC was endorsed by members of the European Parliament during the Plenary through video messages by Anneli Jäätteenmäki, Vice-President European Parliament, and Alojz Peterle, President of the Member of Parliament’s (MEP) Against Cancer. The 2015 edition of the Plenary, entitled ‘Improving... breast cancer screening, diagnosis and care in Europe’, included updates on the ECIBC, highly relevant key-note speeches, and presentations both on related projects and on the situation of breast cancer services in different countries. In addition it focused, via dedicated parallel sessions, on four topics relevant for the ECIBC that, even if they have been debated for some years, are at present still largely under discussion: - continuity of care; -communication (and its assessment) in person-centred services; - key outcomes for studies on breast cancer screening; - volume-outcomes relation in breast cancer care. Participation to the conference was only upon invitation. Ninety-seven persons from outside the JRC participated in this meeting, representing policy makers, patients, stakeholders, as well as representatives from other European Commission Directorates-General. While the JRC staff provided and overview of the ECIBC progress, chairs of the two working groups, the Guidelines Development Group (GDG) and Quality Assurance Scheme Development Group (QASDG) presented interim outputs and plans of the two ECIBC pillars.
