I found this quite interesting. Night workers have an increased risk of cancers generally but not skin cancers. I wonder if it is due to reduced sun exposure or something else?
BOSTON, March 3 (UPI) — Working nights is linked to increased risk of some cancers, heart disease and diabetes, but workers may have less risk of skin cancer, U.S. researchers say.
Lead author Dr. Eva Schernhammer of the Channing Laboratory at Brigham and Women’s Hospital in Boston documented 10,799 incidents of skin cancer in 68,336 women in the Nurses’ Health Study over an 18-year period.
The study, published online in the Journal of the National Cancer Institute, found higher duration of working rotating night shifts was associated with a significantly lower risk of skin cancer.
Although the risk for each skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma — decreased, the strongest association was observed for melanoma, which was associated with a 44 percent decreased risk of melanoma after working shifts for 10 years.
Working night shifts has been linked to decreased production of melatonin, which is known to have cancer-protective properties.
