Chemopreventive

Chemopreventive activity is a type of medicinal activity that is used to prevent or reduce the risk of cancer. This activity is typically characterized by the use of agents, such as natural products, dietary supplements, and chemicals, to reduce the risk of cancer or to reduce the progression of established cancer. It is believed that these agents work by interfering with the formation of cancer-causing agents (carcinogens) or by altering the body's response to them. This can be done through a variety of mechanisms, including blocking the formation of carcinogens, blocking the activation of carcinogens, or inducing the body's natural defense mechanisms to fight off cancer cells. Chemopreventive agents are typically used in combination with other treatments, such as surgery, radiation, and chemotherapy.
