1.9 Cases of Leukemia per 10,000 CT Scans in Children
In the breakdown of results, the study authors from Group Health Research Institute and University of California, Davis note that the risk of developing leukemia was highest from head scans for kids under age 5 with a rate of 1.9 cases per 10,000 CT scans. Younger children and girls seemed more susceptible to solid cancers than older kids and boys. Every 300 to 390 scans of a girl’s abdomen or pelvis was associated with the development of one solid cancer. The study estimates that 4,870 future cancers may be caused by the 4 million pediatric CT scans each year. Cutting radiation doses for the top quarter of exposures may prevent 43% of those cancer diagnoses.
