The preceding decade has seen the production of many cancer at lases. As with other techniques of descriptive epidemiology, these atlases have proved valuable in identifying areas for further re sear~h employing the methods of analytical epidemiology. How ever, the various cancer atlases produceq to date have failed to pro vide a common format of presentation, which has limited their comparability and frustrated in a large measure any attempt to compare risks across national boundaries, boundaries which in terms of environmental exposures may have little meaning. In this volume, many features of cancer atlases are presented and there are discussions on the areas where moves towards standardization could greatly increase the utility of the finished product. In contrast to topographic maps, i. e., representations of natural and man-made features on the surface of the earth, thematic maps concentrate on displaying the geographical occurrence and varia tion of a single phenomenon - the "theme" of the map. The link between thematic and base mapping is rather strong as the themat ic information to be depicted is of greater value if displayed on an accurate base map. Further, the thematic map generally uses statis tical data which are frequently related to internal administrative boundaries for enumeration. The major reason for constructing a thematic map is to discover the spatial structure of the theme of the map and to then relate the structure to some aspects of the under lying environment.

This important new reference book on human cancer provides a global picture of the epidemiology of cancer and its environmental causes. By summarising on a cancer-by-cancer basis geographical, environmental and ethical factors, the volume collates a wealth of information which, taken together, provides valuable insights into the causes of cancer and scope for its elimination and control. The contents include: (1) general epidemiological methods; (2) a review of known or suspected causes; (3) a detailed review of specific cancers; (4) a brief review of legal and ethical implications. The bibliography concentrates on recent key references and reviews.
