Figure 1: Ratio of mortality to incidence in a specific year by cancer type and country income. Case fatality (calculated by approximation from the ratio of mortality to incidence in a specific year) is much lower in highincome countries than in low-income countries for cancers that are treatable, such as childhood leukaemia (026 vs 078) and testicular cancer (005 vs 047), treatable if detected early, such as breast cancer (024 vs 048), or preventable, such as cervical cancer (037 vs 063). Estimates are based on International Agency for Research on Cancer GLOBOCAN data for 2002 and 2008 (http://globocan.iarc.fr) [3].
