Abstract: Selenium has long been known to have a role in preventing cancer, but only in recent years has a deficiency in this element also been shown to function in preventing cancer. Selenoproteins have also been shown to serve as selenium-containing components in cancer prevention, but we are learning that specific members of this protein class can also function in cancer promotion. The involvement of two of these selenoproteins, thioredoxin reductase 1 and the 15 kDa selenoprotein, in promoting cancer is examined in this chapter.
