 +======Antineoplastic Agents======
 +Antineoplastic Agents - Substances that inhibit or prevent the proliferation of NEOPLASMS. ([[meshterm>​Antineoplastic Agents|MeSH]])
 +
 +Anticarcinogenic Agents - Agents that reduce the frequency or rate of spontaneous or induced tumors independently of the mechanism involved. They differ from antineoplastic agents in that they prevent neoplasms from forming. The anticarcinogenic substances can be divided into three categories. The first consists of compounds that prevent the formation of carcinogens from precursor substances. The second group consists of "​blocking agents"​ which inhibit carcinogenesis by preventing carcinogenic agents from reaching or reacting with critical target sites in the tissues. The third group is the "​suppressor agents"​ which act by suppression of expression of neoplasia in cells previously exposed to carcinogens that would otherwise cause neoplasms. ​ ([[MeSH>​68016588|MeSH]])
