NEW YORK (Reuters Health) – Just under half of parents in a recent survey understood that radiation from a computed tomography (CT) scan is tied to an increased risk of cancer for their child.

There has been a growing understanding among the medical community in the past decade that children who have had a CT scan are slightly more likely to develop cancer later in life, researchers said.

One recent study found that for every 10,000 children under age 10 that have a scan, one additional child will develop cancer in the next decade.
