There is clear evidence from industrialized and less-developed societies that cancer incidence and survival are related to socioeconomic factors. This fascinating volume, the first to examine the magnitude of these socioeconomic differences in relation to cancer, provides vital information for all those interested in the relationship between public health and oncology. Nineteen authored chapters are presented in four sections: General considerations; Evidence of social inequalities in cancer; Explanations for social inequalities in cancer; and Socioeconomic differences in health care.
