ECHoS is an European project, funded by Horizon Europe Programme, that aims to support the implementation of the Cancer Mission activities in all Member State and Associated Country (MS/AC) through the establishment and development of National Cancer Mission Hubs (NCMHs) operating at national, regional, and local levels. By establishing NCMHs in each MS/AC, European citizens and organisations in health, research, and beyond, will be voiced and their voices will echo together.
