The Cancer Incidence in Five Continents (CI5) series of monographs, published every five years, has become the reference source of data on the international incidence of cancer. The CI5 databases provide access to detailed information on the incidence of cancer recorded by cancer registries (regional or national) worldwide in two formats:
CI5 X contains information from 290 cancer registries in 68 countries about cancers diagnosed from 2003 to 2007.
CI5 I-X presents the basic data published in the ten volumes of CI5.
CI5 Plus contains annual incidence for selected cancer registries published in CI5 for the longest possible period.
