Jun 21, 2017 · Go to: In May 2011 the International Agency for Research on Cancer (IARC) evaluated cancer risks from radiofrequency (RF) radiation. Human epidemiological studies gave evidence of increased risk for glioma and acoustic neuroma. RF radiation was classified as Group 2B, a possible human carcinogen. Further epidemiological, animal and mechanistic ...
One study of the carbon-black producing industry showed a high proportion of cancers of the skin, particularly melanomas, in equal numbers of carbon-black workers and of a comparison group consisting of other workers in the same plant1. A study from the UK in which workers were followed up beyond retirement showed excesses of cancers of the lung and bladder. The excess of lung cancer occurred ...
Oct 6, 2018 · Group 2B: Possibly carcinogenic to humans Evidence is limited in humans and is less than sufficient in experimental animals; or evidence is inadequate in humans but is sufficient in experimental animals; E.g. aflatoxin M 1, bracken fern, and lead. Group 3: Not classifiable as to its carcinogenicity to humans
Jul 18, 2023 · One of IARC’s major goals is to identify cancer causes. Its carcinogen grouping system is the most widely used system. The organization has evaluated more than 1,000 likely cancer-causing agents and grouped them into one of four groups. IARC Carcinogen Classifications. Group 1: Carcinogenic to humans.

The terms probably carcinogenic and possibly carcinogenic have no quantitative significance and are used simply as descriptors of different levels of evidence of human carcinogenicity, with probably carcinogenic signifying a higher level of evidence than possibly carcinogenic. Group 2A: The agent is probably carcinogenic to human.
Jul 14, 2023 · IARC classified aspartame as possibly carcinogenic to humans (Group 2B) on the basis of limited evidence for cancer in humans (specifically, for hepatocellular carcinoma, which is a type of liver cancer). There was also limited evidence for cancer in experimental animals and limited evidence related to the possible mechanisms for causing cancer.
