Although infectious diseases continue to afflict Africa, the proportion of the overall disease burden in sub-Saharan Africa attributable to cancer is rising, and the region is predicted to have a greater than 85% increase in cancer burden by 2030. This Series of seven papers focuses on cancer control in Africa, outlining the current situation, detailing barriers to care, and presenting ideas to advance cancer care and control in the region.
