The results of the recent evaluation by the International Agency for Research on Cancer (IARC) on carcinogenicity of night shift work have been published in The Lancet Oncology .

The alteration of the circadian rhythm had previously been addressed by the IARC Monographs in 2007. In this updated evaluation, resulting also in the high number of new high-quality epidemiological studies, the working group has selected the definition "night shift work" to better describe the circumstances of the exposure and to reflect on the main basic evidence in cancer studies in humans.

This evaluation will be published in volume 124 of the IARC Monographs.
