The project was carried out in Busia district in Western Province. Women 30 to 39 years old were the focus of the project, since they were most at risk for treatable, precancerous disease. The project was implemented in three phases: (1) a preparatory phase from February 2000 to October 2000, (2) a pilot phase in three divisions from November 2000 to October 2002, and (3) an expansion phase covering the whole district from November 2002 through March 2004. | Cancer incidence mortality and survival by site for 14 regions of the world. Colin D Mathers Cynthia Boschi-Pinto Alan D Lopez Christopher JL Murray Global Programme on Evidence for Health Policy Discussion Paper No. 13 World Health Organization 2001 1. Introduction Cancer was estimated to account for about 7 million deaths 12 of all deaths worldwide in 2000 1 only preceded by cardiovascular diseases 30 of all deaths and by infectious and parasitic diseases 19 . Cancer was also estimated to account for almost 6 of the entire global burden of disease in that same year 1 . More than 70 of all cancer deaths occurred in low- and middle-income countries and although the risk of developing dying from it is still higher in the developed regions of the world the control of communicable diseases as well as the ageing of the population in developing countries point to an increasing burden of cancer worldwide. In fact Pisani et al 2 have projected a 30 increase in the number of cancer deaths in developed countries and more than twice this amount 71 in developing countries between 1990 and 2010 due to demographic changes alone. Rising incidence will only add to this burden. Attempts have been made to quantify the global burden of cancer and estimate site-specific cancer mortality and morbidity 2-6 . Such studies are of considerable importance in helping to better allocate resources towards the prevention and treatment of cancer. In the early 1980 s Doll Peto 7 were already calling attention to the evidence about the avoidability of cancer. According to these authors approximately 75 of the cases of cancer in most parts of the US in 1970 could have been avoided. More recently Parkin et al 8 have estimated that there would have been 22.5 fewer cases of cancers in the developing world in 1990 if infections with hepatitis B virus hepatitis C virus human papillomaviruses EBV HTLV-I HIV helicobacter pylori schistossoma and liver flukes had been prevented. Another estimate suggests .
