UCSD researchers identify link between lack of UV light, colorectal cancer -

UC San Diego School of Medicine SAN DIEGO (KUSI) – UC San Diego School of Medicine researchers have identified a possible link between inadequate exposure to ultraviolet-B light from the sun and an increased risk of colorectal cancer, especially as people age, it was announced Tuesday. Reporting in the journal BMC Public Health, researchers investigated global associations between levels of UVB light one of several types of ultraviolet light that reach the Earth’s surface in 2017 and rates of colorectal cancer across several age groups in 186 countries in 2018. Lower UVB exposure was significantly correlated with higher rates of colorectal cancer across all age groups. After other factors, such as skin pigmentation, life expectancy and smoking were considered, the association between lower UVB and risk of colorectal cancer remained significant for people aged 45 and older.
