New study: Child CT scans can raise brain cancer risk

Though it may not seem surprising to some, a new study out of Cambridge has shown that Child CT scans can raise brain cancer risk.  According to the authors, children who undergo between 5 and 10 CT scans may be 3 times more likely than children who have not had the scans to develop leukemia.  Given the recent push in the U.S. toward more testing and evaluation of head injuries during sports activities, this may create some hesitation by parents to have their children scanned.  However, the neurological risks associated with head injuries and repeat concussions may far outweigh the risk of developing leukemia in some children.  This study, which has received considerable press, is going to create some interesting debates.
