The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).

The IARC said in a release Thursday that it was classifying aspartame as possibly carcinogenic, meaning there is some evidence that it may cause cancer in humans, but that the evidence is far from ...
IARC group 2A agents are substances and exposure circumstances that have been classified as probable carcinogens by the International Agency for Research on Cancer (IARC). [1] This designation is applied when there is limited evidence of carcinogenicity in humans, as well as sufficient evidence of carcinogenicity in experimental animals.
The International Agency for Research on Cancer in 2022 declared occupational exposure during firefighting to be a "group 1 carcinogen," meaning it causes cancer in humans, akin to tobacco and ...
In May 2011, IARC classified radio-frequency electromagnetic fields (RF-EMF) as possibly carcinogenic to humans, notes Nelly Awkar-Lazo, M.D., ...
