Although cancer may be experienced by any age group, incidence increases with time, suggesting in many cases there is a prolonged period from the time of initiation to the time of invasive and metastatic cancer. Accordingly, numerous opportunities for intervention are apparent, either through primary prevention at early stages or through therapeutic interventions during later stages of carcinogenesis. In general, cancer chemoprevention is considered as the use of drugs, vitamins, or other agents to reduce the risk of (or delay the development or recurrence of) cancer. The concept of implementing cancer chemoprevention through the use of nontoxic agents, dietary and natural sources, has emerged as an appropriate strategy for controlling disease progression.
