To classify a substance as causing or be associated with cancer is a serious matter. Significant global efforts by scientists have been conducted into cancer research over the last decades. Government resources have been developed to compile this data so as to help prioritise the more toxic carcinogenic substances we may be significantly exposed to.
For a substance to be classified as Human Carcinogen on toxno it must be defined by the IARC as category 1, 2A and 2B; by the NTP as "known or anticipated to cause cancer"; rated by the EPA_IRIS program in categories A, B1, B2 or C; classified by the OEHHA as "known to the state to cause cancer". See our References and Toxin Profiles and a list of Chemicals with Carcinogenic Proporties for more details. Importantly this list is not exclusive. Many others exist that we are just learning about. Stay informed by signing up on any of our toxin profile pages.
This is a Long List. If looking for a particular chemical you can use the find function on your keyboard while on this page or our site search feature at top right of every page.
