Projections based on the GLOBOCAN 2012 estimates predict a substantive increase new cancer cases per year by 2035 in developing countries if preventive measures are not widely applied. According to the World Health Organization (WHO), millions of lives could be saved each year if countries made use of existing knowledge and the best cost-effective methods to prevent and treat cancer. Therefore, the aim of this study is to estimate a provisional budget against cancer in low and middle incomes countries, according the GNI-PPP, the cancer incidence and the number of population. Economically country classification is determining with the Gross National Income (GNI), per capita, Purchasing Power Parity (PPP), according the administrations of the International Monetary Fund (IMF), the World Bank (WB) and the Central Intelligence Agency (CIA). Cancer incidence data presented are based on the most recent data available at IARC. However, population compares estimates from the US Bureau of the Census. The provisional budget is establishing among the guidelines developed by WHO for regional and national cancer control programs according to national economic development. Provisional budget against cancer is estimated to 24,613.598 (thousands of U.S $) for a population of 12,413,867 persons in Guinea.
