Anticarcinogenesis and Radiation Protection 2, Softcover reprint of the original 1st ed. 1991

The dramatic decrease in the incidence of stomach cancer in industrialized countries during the past 50 years, which is yet to be fully explained, and the observation that carcinogenesis in laboratory animals can be inhibited by antioxidants, retinoids, and caloric restriction, among other influences, challenge us to press on in the search for practical means to prevent cancer. It is in relation to this goal that the studies summarized in this book have special significance. This book is based on the invited and contributed papers presented at the Third Internationai Conference on Anticarcinogenesis and Radiation Protection, held on October 15-21, 1989, in Dubrovnik, Yugoslavia. They cover a broad range of investigations into the mechanisms and inhibition of carcinogenesis. In keeping with recent advances in our understanding of the importance of oncogenes and tumor-suppressor genes in carcinogenesis, many of the reports focus on mutations and related changes at the level of DNA. At the same time, however, other reports deal with nutritional, immunological, endocrinological, and epidemiological aspects. In all, the various reports address carcinogenesis and its inhibition at virtually every level of biological organization. Included in this compendium are timely reviews of diverse and promising research strategies for cancer prevention, as pursued by investigators in different parts of the world. The Organizers of the Conference are grateful to the many scientists who have contributed to the volume, as well as to the sponsors of the Conference, without whose generous support this book would not have been possible.
