The latest generation of hospital scanners could be far more dangerous than previously believed, according to a study showing that as many as one in 80 people could be at risk of developing cancer as a result of being scanned.
Computed tomography (CT) scanners produce a much higher dose of radiation than conventional X-rays and the latest research suggests that the extra exposure could result in a 10-fold greater risk of cancer than is usually cited, scientists said. Researchers from the University of California said: "While CT scans can provide great medical benefits, there is concern about potential future cancer risks because they involve much higher radiation doses than conventional diagnostic X-rays".
