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. So while cancer is unquestionably a global burden, its reach in the developing world points to the need for specialized study on cancer in these countries. 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. The result is a valuable resource for both program leaders and graduate and post-graduate students pursuing careers in international cancer epidemiologic research.
