What is a Group 4 carcinogen?
Compounds or physical factors assessed by IARC (International Agency for Research on Cancer) are classified in four groups based on the existing scientific evidence for carcinogenicity. Group 4: “Probably not carcinogenic to humans” There is strong evidence that it does not cause cancer in humans.
What are carcinogens and its types?
There are three types of chemicals, known as carcinogens, that can cause cancer: Procarcinogens, which cause cancer due to being changed during metabolism. Cocarcinogens, which cause cancer by acting with another chemical. Direct acting carcinogens, which can cause cancer as is.
What are the classification of carcinogens?
Carcinogens can be classified as genotoxic or nongenotoxic. Genotoxins cause irreversible genetic damage or mutations by binding to DNA. Genotoxins include chemical agents like N-nitroso-N-methylurea (NMU) or non-chemical agents such as ultraviolet light and ionizing radiation.
What are carcinogens in?
A carcinogen is an agent with the capacity to cause cancer in humans. Carcinogens may be natural, such as aflatoxin, which is produced by a fungus and sometimes found on stored grains, or manmade, such as asbestos or tobacco smoke.
What are Group 2 carcinogens?
International Agency for Research on Cancer Group 2A: Probably carcinogenic to humans
- Acrylamide.
- Adriamycin (doxorubicin)
- Androgenic (anabolic) steroids.
- Art glass, glass containers, and press ware (manufacture of)
- Azacitidine.
- Biomass fuel (primarily wood), emissions from household combustion.
What is a category 2 carcinogen?
Category 2 carcinogens are suspected human carcinogens. This is based on evidence obtained from human and/or animal studies but which is not sufficient for a Category 1 classification.
How many carcinogens are there?
Since 1971, the agency has evaluated more than 1,000 agents, including chemicals, complex mixtures, occupational exposures, physical agents, biological agents, and lifestyle factors. Of these, more than 500 have been identified as carcinogenic, probably carcinogenic, or possibly carcinogenic to humans.
What are carcinogens examples?
Carcinogens are substances or exposures that can cause cancer. Examples include home and workplace chemicals, environmental or medical radiation, smoke, and even some viruses and medications.
