Antioxidant Vitamins May Reduce Colorectal Cancer Risk, Study by Norwegian Scientists Shows
PRNewswire, Washington, Aug. 19, 1998

Antioxidant vitamins, including Vitamins C and E, may reduce the risk of colorectal cancer, a team of seven Norwegian medical researchers has reported.

Studying more than 100 polyp-bearing patients over a three-year period, the scientists reported that the antioxidants may help prevent new formation of polyps. The study did not find an overall effect on polyp growth, however.

"There are indications that the antioxidant vitamins beta carotene, Vitamins C and E, and selenium may reduce the risk of colorectal cancer," the researchers said in a study supported by the Norwegian Cancer Society.

The purpose of the study was to examine whether dietary supplements of antioxidants and calcium could reduce growth of polyps or inhibit new polyp formation. Seventy-two patients used additional vitamin and mineral supplements. The researchers noted that inhibition of new formation of polyps "is in accordance with the previously demonstrated protective association of a high dietary intake of Vitamins A, C or E on the prevalence of polyps."
