More selenium could slash bladder cancer risk, says study

Increasing the daily intake of selenium from dietary and supplementary sources, could cut the risk of bladder cancer by 70 per cent, suggests a new study from Belgium.

Continued coverage of positive results, like the new study published in the International Journal of Urology (Vol. 13, pp. 1180-1184), could help further increase public awareness of a mineral already associated with reducing the risk of prostate and lung cancer, as well as boosting the immune system.

The authors carried out a population case-control study with 178 cases and 362 controls. Blood samples were taken to assess serum selenium concentrations. After accounting for sex, age, smoking and occupational exposure, the researchers calculated that the risk of bladder cancer was slashed by 70 per cent for those people with blood levels of more than 96 micrograms per litre, compared to those with serum levels of less than 82.4 micrograms per litre. Serum selenium levels between 82.4 and 96 micrograms per litre were associated with a 52 per cent risk reduction in bladder cancer risk.

The European recommended daily intake (RDI) is 65 micrograms.
