Small cancer risk following CT scans in childhood and adolescence confirmed
CT (computed tomography) scans have great medical benefits, but their increasing use since the 1980s has raised some concerns about possible cancer risks, particularly following exposures in childhood. Most previous studies have estimated risks indirectly, and some radiation experts have questioned the validity of these estimates. There is currently much uncertainty and as such, researchers from Australia and Europe carried out a study comparing cancer rates in patients exposed to CT scans at ages 0-19 years compared with unexposed persons of a similar age.
