4P-CAN’s mission is to understand barriers, whether legislative, socio-economic, commercial, or behavioural to the widespread adoption of cancer primary prevention measures across Central and Eastern Europe. By understanding barriers to policy implementation and individual adherence to healthy behaviours, 4P-CAN will improve primary prevention activities and reduce inequalities. With the collaboration of 17 organizations from 11 countries, including both EU and non-EU Balkan countries, as well as Western EU countries, 4P-CAN is dedicated to achieving these goals and fostering a healthier future.
