IARC group 1 Carcinogens are substances, chemical mixtures, and exposure circumstances which have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC). [1] This category is used when there is sufficient evidence of carcinogenicity in humans.
The first type of carcinogen is the physical type which can be ultraviolet and ionizing radiation. The second type of carcinogens is defined as asbestos, tobacco smoke, alcohol, aflatoxin, and arsenic. The third type of carcinogen is biological which highlights infections that can be caused from viruses, bacteria, or parasites. [2]
A 2020 study of 2,658 samples from 38 different types of cancer found that 16% were associated with a virus. [8] These cancers might be easily prevented through vaccination (e.g., papillomavirus vaccines ), diagnosed with simple blood tests, and treated with less-toxic antiviral compounds.
Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
The time from exposure to a carcinogen to the development of cancer is known as the latency period. For most solid tumors in humans the latency period is between 10 and 40 years depending on cancer type. [5] For blood cancers, the latency period may be as short as two. [5]
Found in plastics and paper, some of the potential mammary carcinogens include polysterene and polyamide, which are used in styrofoam to-go containers from restaurants and black plastic spatulas.
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
Although several studies have found lower levels of carcinogens in e-cigarette aerosol compared to smoke emitted by traditional cigarettes, the mainstream and second-hand e-cigarette aerosol has been found to contain at least ten chemicals that are on California's Proposition 65 list of chemicals known to cause cancer, birth defects, or other ...
