Furthermore, some chemically synthesized substances are carcinogenic. Based on animal experiments with substances suspected of being carcinogenic, the International Agency for Research on Cancer (IARC) has classified 50 types of substances that are clearly carcinogenic in Group 1, and approximately 200 types of substances that are suspected of being carcinogenic in Group 2. Most of these are substances that people come into contact with in their jobs or as medicines. The most carcinogenic substance is considered to be aflatoxin.
