The importance of registries in cancer control

Cancer is one of the major causes of morbidity and mortality in the world, with 14.1 million new cases and 8.2 million deaths annually. A marked disparity exists between developed countries and developing countries, with 57% of new cases and 65% of deaths in 2012 occurring in developing countries. This global picture can only be obtained because of data obtained from population-based cancer registries, which allow cancer estimations for different geographic areas. Our objective is to perform a review of different types of registries and their role in the control of cancer. These types of registries are lacking in developing countries. In Central and South America, only 6% of the population is included in cancer registries versus 83% in North America. It is necessary to increase the coverage of cancer registries to obtain more reliable data that will more appropriately guide control programs.
