These include chemicals, complex mixtures, occupational exposures, physical agents, biological agents, and lifestyle factors.

National health agencies can use this information as scientific support for their actions to prevent exposure to potential carcinogens.

Lyon, 20–27 March 2018 IARC Monographs List of Classifications by Cancer Site All News Volume 100 compiles information on tumour sites and mechanisms of carcinogenesis.

About half of the agents classified in Group 1 were last reviewed more than 20 years ago, before mechanistic studies became prominent in evaluations of carcinogenicity.

"This paper is a significant benchmark achievement that lays the groundwork for other types of investigations into differences," says molecular anthropologist Maryellen Ruvolo of Harvard University, who was not involved in the work.

As researchers study the genome in more depth, they hope to find the genetic differences that make bonobos more playful than chimps, for example, or humans more cerebral.

The IARC Monographs have received funding from: Meeting 122: "Isobutyl Nitrite, β-Picoline, and Some Acrylates" is announced.

Lyon, 5–12 June 2018 Meeting 121: "Styrene, Styrene-7,8-oxide, and Quinoline" is announced.

While the function of the small differences in DNA in the three lineages today is not yet known, the Max Planck team sees clues that some may be involved in parts of the genome that regulate immune responses, tumor suppression genes, and perception of social cues.

When the Max Planck scientists compared the bonobo genome directly with that of chimps and humans, however, they found that a small bit of our DNA, about 1.6%, is shared with only the bonobo, but not chimpanzees.

And we share about the same amount of our DNA with only chimps, but not bonobos.

Interdisciplinary working groups of expert scientists review the published studies and evaluate the weight of the evidence that an agent can increase the risk of cancer.

The principles, procedures, and scientific criteria that guide the evaluations are described in the Preamble to the IARC Monographs.
