The European Code Against Cancer (ECAC) is an initiative of the European Commission, developed by the World Health Organization’s International Agency for Research on Cancer (IARC). The ECAC aims to inform people about actions they can take for themselves or their families to reduce their risk of cancer. Leading cancer scientists from across Europe compiled the ECAC based on the latest scientific evidence on cancer prevention, coming up with twelve recommendations that most people can follow without any special skills or advice. It has been estimated that almost half of all deaths due to cancer in Europe could be avoided if everyone followed the recommendations.
