Artus Paty, Deputy General Manager of the Henri Becquerel Center in Rouen, and Emmanuelle Hoche, Patient Experience Project Manager and Coordinator of the Becquerel-LAB, reflect on the creation of the Becquerel-LAB. Launched a few years ago, this initiative aims to promote patient involvement in shaping the new Becquerel Center, as well as in care practices and the training of healthcare professionals. They share examples of how patients and caregivers can actively contribute, and highlight collaborations with other Unicancer institutions, in France and across Europe that are embracing these new approaches.
