Weak surveillance and policy attention to cancer in global health: the example of Mozambique

Cancer is an emerging public health problem in sub-Saharan Africa due to population growth, ageing and westernisation of lifestyles. The increasing burden of cancer calls for urgent policy attention to develop cancer prevention and control programmes. Cancer surveillance is an essential prerequisite. Only one in five low-income and middle-income countries have the necessary data to drive policy and reduce the cancer burden. In this piece, we use data from Mozambique over a 50-year period to illustrate cancer epidemiological trends in low-income and middle-income countries to hypothesise potential circumstances and factors that could explain changes in cancer burden and to discuss surveillance weaknesses and potential improvements. Like many low-income and middle-income countries, Mozambique faces the dual challenge of a still high morbidity and mortality due to infectious diseases in rural areas and increased incidence of cancers associated with westernisation of lifestyles in urban areas, as well as a rise of cancers related to the HIV epidemic. An increase in cancer burden and changes in the cancer profile should be expected in coming years. The Mozambican healthcare and health-information systems, like in many other low-income and middle-income countries, are not prepared to face this epidemiological transition, which deserves increasing policy attention.
