At present, more than 200 population-based cancer registries exist in vari-
ous parts of the world. They cover about 5% of the world’s population, but the
proportion is much greater in developed countries than in developing ones.
Moreover, in developing countries, registries are more likely to cover urban
areas, where access to diagnostic and treatment services is better.
Nationwide cancer registration operates in some countries such as England
& Wales, Scotland, the Nordic countries, Canada, Australia, New Zealand,
Israel, Cuba, Puerto Rico and The Gambia.
