Source-ANI: Night work can increase the risk of a number of cancers in men, according to a new study.
It is one of the first studies in the world to provide evidence among men of a possible association between night work and the risk of prostate, colon, lung, bladder, rectal, and pancreatic cancer and non-Hodgkin’s lymphoma.
The study was conducted by a research team from Centre INRS–Institut Armand-Frappier and Centre de recherche du Centre hospitalier de l’Universite de Montreal.
“Exposure to light at night can lead to a reduced production of the sleep hormone melatonin, inducing physiological changes that may provoke the development of tumours. This hormone, habitually released in the middle of the night in response to absence of light, plays a pivotal role in hormonal functions and in the immune system,” explained Professor Marie-Elise Parent of Centre INRS–Institut Armand-Frappier, the study’s lead investigator.
