chemoprevention

Chemoprevention is the use of chemical agents to prevent or slow the development of cancer. This medical strategy intervenes in the early precancerous stages of carcinogenesis, aiming to reverse tumor formation.12

Many chemopreventive agents, both natural and synthetic, have been identified. Some of the most promising compounds are found in vegetables and fruits, such as dithiothiones in broccoli and cauliflower. Additionally, certain anticancer drugs, like antiestrogen drugs such as tamoxifen, show promise in preventing cancer, notably reducing the incidence of breast cancer. Chemoprevention research trials often include individuals with precancerous lesions or a history of cancer who are at risk for developing a second tumor.2
