Given the interest in working in a coordinated way and after several meetings on the sharing of the needs of the registries, in November 2010 the Spanish Network of Cancer Registries (REDECAN) was created, which is made up of all Spanish population cancer registries and the Spanish Registry of Childhood Tumors (RETI).
Experience in Spain

Various projects carried out in previous years demonstrated the possibility and benefit of working together.
The results obtained in collaboration were important, such as the publication of the monograph Cancer control in Spain in the Annals of Oncology in May 2010.
Experience in Europe
In some European countries, such as France and Italy, the situation was similar to that of Spain. There were records in different geographic areas that covered only a part of the population.
In France, the Network of Population Cancer Registries FRANCIM (France-cancer-incidence et mortalité) was created in 1991 and in Italy the Associazione Italian Registri Tumori (AIRTUM) was founded. Since their creation these networks have achieved a great scientific production.
