title: Chemo/Dietary prevention of cancer: perspectives in China.
abstract: Cancer is a major disease worldwide and different approaches are needed for its prevention. Previous laboratory and clinical studies suggest that cancer can be prevented by chemicals, including those from the diet. Furthermore, epidemiological studies have suggested that deficiencies in certain nutrients can increase the risk of some cancers. In this article on chemo/dietary prevention, examples will be given to illustrate the effectiveness of chemopreventive agents in the prevention of breast, colon and prostate cancers in high-risk populations and the possible side effects of these agents. The potential usefulness of dietary approaches in cancer prevention and the reasons for some of the failed trials will be discussed. Lessons learned from these studies can be used to design more relevant research projects and develop effective measures for cancer prevention in the future. The development of effective chemopreventive agents, the use of nutrient supplements in deficient or carcinogen-exposed populations, and the importance of cohort studies will be discussed in the context of the current socioeconomic situation in China. More discussions are needed on how we can influence society to pay more attention to cancer prevention research and measures.
