Cancer in Sub Saharan Africa Vol III is testimony to the commitment of IARC and UICC to the recommendation in the WHA resolution "to collect high-quality population-based incidence and mortality data on cancer, for all age groups by cancer type, including measurements of inequalities, through population-based cancer registries, household surveys and other health information systems in order to guide policies and plans". It represents the fruits of the labours of the members of the African Cancer Registry Network over the past few years, bringing together their results in terms of the incidence of different cancers (by age group and sex) in the populations which they serve, for periods generally between 2010 and 2017. This volume includes results from 31 cancer registries in 22 countries, eight of which are new (not appearing in Volume II).
