According to the World Health Organization's 2008 GLOBOCAN report, 64% of global cancer deaths -- and 56% of cancer cases -- were registered in countries in Africa, Asia, or Latin America.

Cancer Epidemiology: Low- and Middle-Income Countries and Special Populations reviews the current status of cancer epidemiologic research and training -- rationale, requisite infrastructure, methodologic principles, and illustrative examples in low- and middle-income countries -- in order to facilitate future advances by trained health professionals.
