Multivitamins Linked to Breast Cancer Risk
Study Shows Higher Risk of Breast Cancer Among Women Who Report Taking Multivitamins
Designing New Studies
More studies are needed to get to the bottom of the issue, says Gilbert
Ross, MD, medical director for the American Council on Science and Health, a
New York City-based consumer education group.
"If you really want to take multivitamins, this study is no reason to stop,"
Ross says. "Of course, on the other hand, I would advise anyone concerned that
there is no good health or medical reason to take multivitamin supplements,
except in rare cases of malnutrition."
"Focus on looking at food as the source of minerals and nutrients that we
need in our lives," says Lorenzo Cohen, PhD, a professor and director of the
Integrative Medicine Program at the University of Texas M.D. Anderson Cancer
Center in Houston.
"We know that multivitamins and supplements are useful for people who are
malnourished or deficient in particular minerals or vitamins, but more is not
necessarily better," he says. "In a society where individuals have a
vitamin and minerals at appropriate levels, supplementing with a multivitamin
may not decrease your risk of cancer."
