Selenium May Reduce Colon Cancer Risk
(HealthDayNews, 11/16/04)
When Elizabeth T. Jacobs of the Arizona Cancer Center,
and colleagues, reviewed the data from three trials of colon
cancer patients--the Wheat Bran Fiber Trial, the Polyp
Prevention Trial and the Polyp Prevention Study--the
investigators discovered that having high selenium levels
significantly reduced the risk of a subject's colon cancer
recurring, as compared with those who were
selenium-deficient. Researchers believe that selenium can
activate cancer-preventing genes and alter the way the body
metabolizes the fatty acids found in red meat. Scientists
have noted that selenium intake depends on the concentration
of the mineral in local soil and that people who live where
amounts are low have an increased risk of colorectal and
other malignancies. While the current findings suggest that
this trace mineral suppresses colon cancer, Jacobs adds that
selenium may protect against lung and prostate cancer as
well.
