The project is imbued with the whole problematic of patient follow-up and patient support, taking into account the experiences and needs of breast cancer patients. It concerns the dissemination of knowledge through the implementation of a specific clinical innovation designed to optimizing breast cancer patient pathway. The " Patients en réseau " association offers us to participate at the web platform evolution Mon Réseau Cancer du Sein in adapting it.

One of the French Cancer Plan 2014-2019 objectives is to improve the town-hospital coordination and information's exchange between professionals. This research project aims to reach this important objective of exchange development and the amelioration of the coordination concerning breast cancer women. Breast cancer requires the integration of aggressive treatments implying physical, psychological and social consequences. That's why an optimized care pathway needs a coordinated and multidisciplinary organization, and more particularly a personalized approach taking into account the whole patients' needs in physical, psychological and social perspectives. To reach this goal, it is important to support those patients, to answer their needs for a better disease management in their own health pathways. The research issues lie in this outcome.
