The incidence of cancer in developing countries now, for the first time in history, matches that in the industrialized countries and the incidence of cancer in general is growing worldwide. In the year 2003, there were ten million estimated new cancer cases the world over of which there were four million in the developing countries. Its is predicted by the WHO that by the year 2020 this number will increase to 15 million of which 10 million will be in the developing world. With increasing wealth and industrialization has come a rapid change in the lifestyles, and this is likely to raise the national tumor burden. Thus, cancer once considered an uncommon medical problem is no more so and in the near future 50% of cancers worldwide will occur in countries labeled today as developing countries.
