High
Levels of Selenium Decrease Risk of Skin Cancer

High blood levels of selenium decrease the risk of basal cell carcinoma by 57% and squamous cell carcinoma
by 63%.
Antioxidant nutrients, which include carotenoids, vitamin E and selenium can prevent skin
damage caused by ultraviolet rays from sunlight, but it is unclear whether these nutrients can influence skin
cancer risk. A recent study sought to determine whether there is any association between serum concentrations of
antioxidant nutrients and skin cancer. The study included 485 patients who were followed from 1994 to 2004. They
provided blood samples, which the researchers measured for levels of carotenoids, vitamin E and selenium and their
relation to basal cell and squamous cell carcinoma occurrence.
The researchers found that while no relationship was found between serum carotenoids or vitamin E levels and skin
cancer risk, there was a significant relationship with selenium. The results revealed that those with the high
blood levels of selenium had a 57% decreased risk of basal cell carcinoma and a 63% reduced risk of squamous cell
carcinoma, compared to those with the lowest selenium blood levels. It appears that high serum levels of selenium
are associated with a decreased risk of future skin cancer.[1]

Natural Cancer Treatment Pearl
Selenium appears to have a bi-phasic effect. Small amounts do not decrease the risk of skin cancer while high doses
help prevent skin cancer.
