The researchers looked at 14 different studies that examined 20,000 children. Of those, about a third of them had acute lymphoblastic leukemia. Researchers believe the earlier exposure to germs can strengthen a tot's immune system — even to leukemia.

While there are unknown factors that cause leukemia, this report may offer a peek into how the disease might be prevented.
