Work when others are sleeping: Hospital nurses, flight band workers or flight attendants regularly work through the night. For the body, it is not only burdensome because of fatigue. The International Agency for Cancer Research (IARC) recently confirmed, on the basis of recent studies in its earlier estimation, that night work is likely to be cancerous. However, many questions are still open.
The work in Nachtschicht falls into that Group 2A – "probably carcinogenic". These include some of the controversial plant protection ingredients glyphosate and the distortion of red meat. Whoever explains the agency with its seat in Lyon (F) is called "confined news" that night work can lead to tumors in the breast, prostate and intestine. The increase is hardly considered a risk assessment by the agency.
Layer work has an influence on cancer risk
The statements about the probability triggered by night work cancer are heavy. The experts' assessment could easily clarify the question of whether night shift work has any influence on the cancer risk, says Hajo Zeeb, who is involved in the IARC stage of the Prevention and Evaluation Department at the Leibniz Institute for Prevention Research and Epidemiology (Bremen).
"Whoever is at large with the influence of night work on the cancer risk, does not readily understand with this estimation. This also requires a so-called risk assessment. ”In addition, individual aspects of a single person in shift work are not considered in the assessment, says Zeeb. The estimate of the expert group appeared in the journal "The Lancet Oncology" in July. At first, the IARC hated night work as a probable crustacean vaccine already in 2007.
Night shift was particularly unhealthy
It was the scientists who assumed that shift work could be generally crustacean. The new studies now stated that, above all, this work can lead to cell changes, at which day-night rhythm is disturbed. The re-rating for the IARC takes over a working group of 27 science students from 16 countries. The experts therefore analyzed scientific literature and studies.
"It was a widely shared discussion of scientific data on the subject in many parts," said Zeeb, the part of this expert committee. "Some recent studies found no correlation between night shift work and cancer, other repeated citing convincing risks. And the order of biological findings is too complicated. ”(Pbe / SDA)
