but also the possibility of intervention in specific stages. In Human behavior, including stress and other factors, plays an important role in neoplasia, although too little is known addition, variables which affect cancer development as well on the reasons for such development. Carcinogens, which as some endogenous factors can be better delineated help initiate the neoplastic process, may be either synthetic through such investigations. The topics of this volume encompass premalignant non or naturally-occurring. Cancer causation may be ascribed to invasive lesions, species-specific aspects of carcinogenicity, certain chemicals, physical agents, radioactive materials, viruses, parasites, the genetic make-up of the organism, and radiation, viruses, a quantum theory of carinogenesis, onco bacteria. Humans, eumetazoan animals and vascular plants genes, and selected environmental carcinogens. are susceptible to the first six groups of cancer causes, whe reas the last group, bacteria, seems to affect only vascular plants. Neoplastic development may begin with impairment ofJmdy defenses by a toxic material (carcinogen) which acts as an initiator, followed by promotion and progression to an overt neoplastic state. Investigation of these processes Series Editor Volume Editor allows not only a better insight into the mechanism of action Hans E. Kaiser Elizabeth K. Weisburger vii ACKNOWLEDGEMENT Inspiration and encouragement for this wide ranging project on cancer distribution and dissemination from a comparative biological and clinical point of view, was given by my late friend E.

The fourth annual American Institute for Cancer Research (AICR) conference on diet, nutrition and cancer was held at the L'Enfant Plaza Hotel in Washington, D. C. , September 2~3, 1993. In keeping with present concerns and in line with current trends, the theme was "Diet and Breast Cancer. " This proceedings volume is comprised of chapters from the platform presentations of the two day conference and abstracts from the poster session held at the end of the first day. Experimentally, there is sufficient evidence to support a relationship between dietary fat and the risk of breast cancer. A meta-analysis was provided by data from 114 experiments with over 10,000 animals, divided into groups fed ad libitum on diets with different levels or sources of fat, or different levels of energy restriction. This exercise suggested that linoleic acid was a major determinant of mammary tumor development but that other fatty acids also enhanced mammary tumor development in animals. However, as mentioned by several speakers, results from epidemiological studies often are conflicting, thus leading to confusion among both health professionals and the public. Surveys of specific populations which have migrated from countries with low breast cancer rates to those with higher rates are often some of the most compelling studies with respect to a high fat diet-breast cancer association. Nonetheless, various cohort and prospective studies, some quite large, did not appear to show a relationship between consumption of fat (any type) and breast cancer.
