The ultimate goal of cancer chemoprevention research and development is the identification of pharmaceutical or dietary constituents that will prevent cancer. Cancer Chemoprevention presents the proceedings of a large workshop on cancer chemoprevention that highlights the latest knowledge in the field, in addition to issues and ideas concerning future directions. Retinoids, sulfur compounds, and a large number of many naturally occurring cancer inhibitors in the diet are discussed, including green tea, garlic constituents, citrus fruit oils, and beans and seeds containing protease inhibitors. Compounds that may prevent the formation of carcinogens in food are covered, and the mechanisms by which chemical or dietary agencts produce cancer inhibitors are discussed.
