Background to Eusoma guidelines and statements.

The European Society of Mastology (Eusoma) is committed in writing and diffusing guidelines on Breast Cancer, aiming at harmonising the quality of Breast Cancer care throughout Europe. To achieve this Eusoma organises scientific meetings, "workshops" or "Consensus meeting", inviting European experts from the different disciplines involved in the multidisciplinary management of Breast Cancer patients, to give their contribution in drafting "guidelines" or "consensus statements". In this regard Eusoma Executive Committee members found it appropriate to define the rules to organise its scientific meetings and to write the documents resulting from these meetings, i.e guidelines or statements. This will guarantee an homogeneity in the meeting organisations and in drawing up the scientific documents.
