Neville, From another group. Hope this helps. - Steve N "From my recently updated anti-cancer protocol <http://www.tbyil.com/anticancer.htm> :
The best form of supplemental selenium for fighting cancer appears to be methylselenocysteine. The most common form of supplemental selenium is selenomethionine whose general proteins have no anticancer activity. Another form, sodium selenite is more frequently metabolized to the toxic metabolite hydrogen selenide (H2Se), which does have anticancer effects but is more toxic than selenomethionine. Its primary mode of killing cancer cells (and at high levels, normal cells) is through the process of cell necrosis. Cell necrosis provokes inflammation and may kill healthy cells along with cancer cells. The recommended form of selenium, methyselenocysteine is found naturally in some vegetables including garlic, brassicas, leeks, and onions, especially when these are grown in high selenium soil. Methylselenocysteine is easily converted to methylselenol which has been demonstrated to be an effective anticancer form of selenium. Rather than killing cancer cells by necrosis, methylselenol kills cancer cells through apoptosis. Apoptosis is an orderly process of cellular self-destruction that does not provoke inflammatory responses. Methylselenol is also known to inhibit angiogenesis in beginning cancer tumors. Angiogenesis, the creation of new blood vessels, is necessary for cancer cells to grow into a tumor. For cancer prevention, doses of 200 to 400 mcg of methylselenocysteine are generally considered safe without medical supervision. Nutritionally-oriented physicians may use as much as 900 to 2,000 mcg selenium from methylselenocysteine daily as part of a comprehensive cancer treatment protocol. Tony"
