A recent study from Belgian researchers has found that a daily intake of selenium, from dietary or supplementary sources could cut the risk of bladder cancer by up to 70 percent.
The findings, published in the International Journal of Urology were based on a study with more than 500 participants.
After accounting for sex, age, smoking and occupational exposure, researchers found that the risk of developing bladder cancer was greatly reduced, by up to 70 percent, when blood levels of selenium were more than 96 micrograms per litre. Every 10 micrograms per litre increase in serum selenium levels was associated with a 14 percent reduction in the risk of bladder cancer.
Bladder cancer is diagnosed in nearly 350,000 people every year worldwide. It is three times more likely to affect men than women.
Selenium rich foods include most plant foods, some meats and seafood and Brazil nuts.
