Prenatal Vitamins Could Reduce Brain Cancer Risk in Children
The results of a large study indicate that mothers who took prenatal vitamins during pregnancy helped reduce the risk of their child developing neuroblastoma. Neuroblastoma is a type of brain tumor that is found primarily in children and is the most common type of cancer occurring in infants. Neuroblastoma affects nine out of every million children under the age of 15 in the United States.
In one of the largest studies of its kind, researchers compared 538 children diagnosed with neuro-blastoma against 504 children who did not. The mothers of the children were then interviewed about their vitamin usage before and during the pregnancy.
Researchers found that daily vitamin and mineral use in mothers in the month before pregnancy and each trimester resulted in a 30 to 40% reduction in the risk of their children developing neuroblastoma. This study builds on previous research showing a beneficial association between vitamins, minerals and cancer prevention.
