Here's a message for all those who thought consuming drugs and
supplements helped reduce cancer risks: Think again.
According to a landmark Women's Health Study of nearly 40,000 women,
neither low-dose aspirin nor vitamin E lowered overall cancer cases
or deaths. Researchers used data from the study and compared the
effect of aspirin, vitamin E and a placebo on various diseases over
a decade. The much-anticipated results contradicted some earlier,
less rigorous studies. For example:
However, the Women's Health Study was not able to support this
conclusion.
No Help From Aspirin and Vitamin E
The study involved nearly 40,000 healthy women (older than age
44). Each woman was randomly assigned to take 100 mg of aspirin
or a placebo and 600 IU of vitamin E or a placebo; they consumed
the pills every other day for a decade.
Overall, the data on vitamin E did not show any cancer benefit,
and the one benefit found with taking low-dose aspirin -- a reduction
in lung cancer deaths -- could have been the result of chance.
Moreover, according to the American Cancer Society, the use of
aspirin and vitamin E may have overshadowed better and underused
ways to reduce one's cancer risk based on simple lifestyle changes
such as quitting smoking and periodic cancer screenings.
