In Europe, cancer registries are typically organized at regional, national, and international levels. The European Network of Cancer Registries (ENCR), established by the European Commission, enhances collaboration among registries. National registries exist in many European countries, such as the UK National Cancer Registration and Analysis Service (NCRAS) and the French National Cancer Institute (INCa). These registries feed data into larger databases, including the European Cancer Information System (ECIS), which provides comprehensive insights into cancer statistics across Europe.
