Besides preventing birth defects in the brain and spine and other congenital abnormalities, the folic acid found in prenatal multivitamins has now been shown to prevent cancer in children whose mothers take the vitamins during pregnancy.A new Canadian study, appearing online in the journal Clinical Pharmacology & Therapeutics, estimates prenatal multivitamin supplements can save hundreds of children each year in Canada -- where only 40 to 50 percent of women take prenatal vitamins -- from developing leukemia, brain tumors, or neuroblastoma. And the vitamins may prevent 900 cases of pediatric leukemia and more than 300 brain tumor cases annually in the United States.
It's not clear which vitamins or minerals, and in what amounts, could be protecting babies from cancer, but it's possible folic acid -- critical for cellular function -- may be acting alone.
One thing is certain, says lead investigator Dr. Gideon Koren -- this is one inexpensive way to prevent cancer.
1. As a parent of a child with Neuroblastoma, who DID take prenatal vitamins, this article has been bothering me. First - a straw poll of other NB parents shows almost all of us took prenatal vitamins. Moreover, what I do not see addressed in this study is that the neuroblastoma incident rate is virtually THE SAME in developed and non-developed countries. If prenatal vitamins really helped to prevent neuroblastoma why don't we see a difference in the rate it occurs in countries where most of the population takes prenatal vitamins?
