The Type Of Selenium Used To Treat Cancer Is Critical To Success

Researchers in two earlier clinical trials that used selenium to fight cancer came up with conflicting results: one showed that selenium reduced cancer risk, while the other showed no beneficial effect at all. But U.S. and Australian scientists may have found a reason for the discrepancy in the results of the trials: the types of selenium used in the two studies were different. For the new study, the researchers analyzed how two forms of selenium – SeMet and MeSeCys – are processed in human lung cancer cells. MeSeCys killed more lung cancer cells than SeMet, and the cells treated with MeSeCys processed the selenium differently than cells treated with SeMet.
