Younger Siblings Give You Brain Tumors
A study done in Sweden shows that people with four or more siblings were twice as likely to develop a brain tumor as people with no siblings. The correlation was only found with the number of younger siblings, not with the number of older siblings.
"Since the size of a family and the number of younger siblings correlate with the incidence of brain tumors, this suggests infectious agents may be causing the disease," said study author Andrea Altieri, DSc, with the German Cancer Research Center in Heidelberg, Germany. "The number of siblings a person has indicates they were exposed at an early age to infections, since children come in close contact with each other and thereby share exposures to many infectious agents."
