Anticarcinogen
Anticarcinogen
Anticarcinogen (pronunciation: an-ti-kar-sin-o-gen) is a substance that counteracts the effects of a carcinogen or inhibits the development of cancer.
Etymology
The term "anticarcinogen" is derived from the Greek words "anti" meaning against, "karkinos" meaning crab or cancer, and "genes" meaning born of, produced by.
Definition
An anticarcinogen is a substance or compound that reduces the likelihood of, or prevents, the formation of cancer in living tissue. This can be achieved by blocking the DNA damage that initiates carcinogenesis, or by arresting or reversing the progression of premalignant cells where such damage has already occurred.
Types of Anticarcinogens
There are three main types of anticarcinogens:
- Blocking Anticarcinogens: These are substances that prevent carcinogens from reaching or reacting with critical target sites.
- Suppressing Anticarcinogens: These are substances that prevent the evolution of the carcinogenic process in cells that have already been exposed to carcinogens.
- Antioxidants: These are substances that neutralize harmful free radicals in the body, which can damage cells and lead to cancer.
Related Terms
