1. INTRODUCTION 1.1 Cancer as a global problem Out of an estimated total of 50 million deaths annually in the world, more than 5 million are attributed to cancer (2). In Europe and North America, under present mortality conditions, about one-fifth of the population will die of cancer (3). Until recently, the mortality from cancer was numerically serious relative to the mortality from infectious and nutritional diseases only in developed countries. However, with increasing control of the latter diseases, cancer is rapidly becoming a major cause of morbidity and mortality throughout the world. More than half the world's population now lives in countries where cancer is among the top ranking causes of death. There can be no doubt that cancer will be a major challenge in the years ahead. A rough WHO estimate, based on expected demographic and health status trends, suggests that by the year 2000 (i.e., within less than a quarter of a century) the number of cancer deaths may rise by more than 50% to approximately 8 million annually. This prediction is based on three trends. (1) Changes in the health spectrum and demographic structure of the population. With successful efforts in developing countries to reduce the number of premature deaths, life expectancy at birth will continue to increase, as will the proportion of a birth cohort surviving to ages in which cancer risks are high. Declining mortality, accompanied in many countries by decreasing fertility, can be expected to work towards a rise in the population in the high-risk age-group, in absolute as well as in relative terms.
