NOTE: Number of countries, according to type of data source, and method used to estimate national incidence from this source.

Methods: 1, Rates projected to 2012; 2, Most recent rates applied to 2012 population; 6, Estimated as the weighted average of the local rates; 7, One regional cancer registry considered representative; 8, Rates for all cancers partitioned using relative frequency data; 9, Rates from neighboring countries or registries in the same area.
