Abstract

In Africa, there were an estimated 681,000 new cancer cases and 512,000 deaths in 2008. Projections to 2030 show a startling rise, with corresponding figures of 1.27 million cases and 0.97 million deaths resulting from population growth and aging alone. The figures make no assumptions about incidence rates which may increase due to the further introduction of tobacco and a more westernized lifestyle. The current situation in many parts of Africa with respect to health care systems suggests that improved cancer treatment would be an insufficient response to this increasing burden. Much could be achieved through cancer prevention by applying current knowledge about major risk factors and the natural history of the disease. For example, vaccination against hepatitis B virus and human papilloma viruses would prevent the occurrence of two of the most common cancers in Africa, liver and cervix, respectively, in the long-term. Strong measures to prevent the widespread introduction of tobacco must be a priority. Early detection and treatment of cervical and breast cancers using approaches applicable now in Africa would provide immediate value, as would the management of human immunodeficiency virus (HIV) infection in respect to HIV-associated malignancies. In parallel, further research is needed into the causes of cancer and the barriers to implementation of promising prevention strategies. Underpinning all is the need for African governments to look forward and prioritize cancer through national cancer control plans, to invest in public health infrastructure and to ensure the adequate training and support for people in cancer prevention and control. Given this core commitment from within Africa, international partners can provide complementary support in a cooperation that permits action now to mitigate the impending tragedy of cancer in the continent of Africa.
