Lower your risk of skin cancer by 60% with selenium
Added 02.06.2009
Summer is upon us and for many of us that means more time spent under the hot sun; but overexposure to the sun can be very damaging and increase your risk of skin cancer. Selenium, researchers say, can cut that risk by up to 60%.
Skin cancer cases on the rise.
Cancer Research UK estimates that there are about 100,000 new cases of skin cancer every year in the UK alone. There are two main types of skin cancer (non-melanoma and malignant melanoma) both of which are on the increase. Tanning beds and overexposure to the sun (repeated sunburns) can increase your risk of both types of skin cancer and so can contact with arsenic, exposure to radiation, chronic inflammatory skin conditions and burn, scar and tissue complications. Up to 80% of patients taking immunosuppressant drugs (given after an organ transplant) develop non-melanoma skin cancer.
Selenium reduces skin cancer risk.
A study published this year in Cancer Epidemiology, Biomarkers & Prevention reveals that selenium reduces the risk of basal cell carcinoma and squamous cell carcinoma, the most common forms of non-melanoma skin cancer.
The Scientific Study
Background information
485 adults from an Australian community were examined for associations between blood levels of selenium, and other antioxidant nutrients, and incidence of basal cell carcinoma and squamous cell carcinoma for a period of eight years.
Results
The highest selenium levels (between 1.3 and 2.8 micromoles/litre) were linked to a 57% reduced risk of basal cell carcinoma and a 64% reduced risk of squamous cell carcinoma compared to the lowest selenium levels (0.4 to 1.0 micromoles).
What is selenium?
Selenium is an essential trace mineral that protects intracellular structures against oxidative damage. It is vital for the function of over 80 proteins in our body that help build heart muscles and maintain healthy sperm.
Is your selenium level too low?
Please see Dr. Bo Nielsen's comments below.
How to get sufficient levels of selenium.
Natural sources of selenium include Brazil nuts, seafood, organ meats, eggs, cereals and grains, but the selenium content is dependent on how much of the mineral is present in the soil and how much is absorbed by crops and plants or indirectly by eating meat from animals that grazed on selenium-rich crops and plants. Quite often, the amount of selenium from these food sources is just not enough and supplementation with a high quality multivitamin that contains selenium (such as Doctor's Natural Vitamins) is a much better alternative.
