Cancer Is a Global Problem

Cancer is clearly a worldwide problem. The incidence and mortality rates for various cancers are similar, though not identical, among developed countries. In the developing world, as countries become more westernized and their populations achieve longer life expectancy, cancer rates are increasing. Although there are differ ences among developing and developed countries in the incidence rates of certain cancers, lung cancer is the most common cancer among men in both regions of the world and breast cancer is the most common cancer in women (Fig. 3-4).5 There are, however, regional differences in the distribution of various cancers in different regions of the world that reflect differing etiologic factors. For example, infectious etiology plays a greater role in certain parts of the world, e.g., the role of schistosomiasis infections in causing bladder cancer in parts of Africa and that of hepatitis B infections in liver cancer in China

Cancers of the stomach and uterine cervix are higher in parts of the developing world, whereas colorectal and prostate cancers are higher in the developed world.5 The global death rate due to cancer is estimated to be more than 6 million people annually, with about 10 million new diagnoses every year. Over 22 million individuals have been diagnosed with cancer worldwide. Thus, there is a global and growing cancer problem.
