New study suggests link between medical imaging and pediatric cancer risk

Medical imaging, like X-rays and CT scans, are routine, non-invasive and painless tools used by doctors to make diagnoses. But a recent study of about 4 million children published in the New England Journal of Medicine suggests that the radiation exposure from imaging could pose a risk for pediatric cancer. John Yang speaks with Dr. Rebecca Smith-Bindman, the study’s lead author, to learn more.
