Children who undergo CT scans at small increased risk of cancer

(May 22, 2013 - Insidermedicine)

From Australia - A new report published in the BMJ finds that children and adolescents who undergo CT scans are at a small increased risk of cancer. Researchers reviewed data on a cohort of 10.9 million people, following individuals who were exposed to CT scans for a mean length of 9.5 years and those who were unexposed for just over 17 years. Results showed that incidence rates of cancer were 24% higher in those who were exposed. As well, risk of cancer increased 16% of every additional scan. Researchers estimate that in a group of 10,000 children and adolescents exposed to one CT scan, there would be an extra six cancers that occurred.
