The term "chemoprevention," which was coined in 1976 (2), describes the use of specific natural, synthetic, or biologic agents to reverse, suppress, or prevent the development of disease.
Chemoprevention is an appealing approach to treating patients with a variety of medical conditions. For instance, cardiac patients who take low-dose aspirin do so in hopes of preventing a future ischemic event. Cancer chemoprevention's best model is early-stage breast cancer, for which hormonal agents are used to prevent recurrence and contralateral disease in patients with the appropriate hormone receptor status.
Both basic biologic research and clinical chemical intervention are the underpinnings of chemoprevention aimed at delaying or halting the
