n.
The use of chemical agents, drugs, or food supplements to prevent the development of cancer.

che′mo·pre·ven′tive adj. & n.

chemoprevention

the use of natural, synthetic or biological substances to suppress or prevent a disease such as cancer. Also called chemoprophylaxis.
Nutrition The use of drugs, chemicals, vitamins or other substances in the diet to prevent or decrease the incidence of a disease—e.g., cancer; chemopreventive agents—supported by some ‘soft’ epidemiologic data—are vitamin-rich fruits, bran, other dietary fibers, and cruciferous vegetables
Oncology Intervention with chemical agents before malignancy—invasion—across an epithelial basement membrane develops, to halt or slow carcinogenesis; chemoprevention aims to directly modulate specific steps in carcinogenesis, prevent DNA damage by free radicals, suppress epithelial proliferation, and promote epithelial differentiation

chemoprevention

Nutrition The use of drugs, chemicals, vitamins or other substance in the diet or to prevent or ↓ the incidence of a disease–eg, CA; chemopreventive agents–supported by 'soft' epidemiologic data are vitamins A, C, E, bran, other dietary fibers, and cruciferous vegetables. See Antioxidant, Antioxidant therapy. Cf Chemoprophylaxis, Unproven methods for cancer management.
