Cancer is sometimes thought of as a disease of wealthier countries, but it is a major cause of morbidity and mortality in poorer ones as well.Indeed, by the end of this decade, about 150 million people worldwide will have cancer, with approximately 60% of them residing in developing countries.
Although fewer people in developing countries live to the age at which cancer is most prevalent, inadequate nutrition and environmental exposures to viruses and toxins, combined with a paucity of diagnostic and treatment options, increase cancer’s incidence and lethality.
