awareness: night shift increases breast cancer risk

Daily dose of awareness

Another risk factor that is receiving attention is working long-term night shift or changing sleeping time or habits frequently. Although current research is studying this phenomenon, the theory is that long-term graveyard shifts affect the body’s circadian rhythm, which assists in the production of melatonin, a tumor suppressor. The WHO’s International Agency for Research on Cancer (IARC) in 2007 reported preliminary findings of a study by a working group that reclassified night shift work as a probable risk as opposed to its previous label as possible risk. Studies still need to determine the cause for the increased risk. In the meantime, the Danish government began compensating women on night shift for the increased risk of breast cancer.
