CT scans for children "may increase the risk of brain cancer
Multiple CT scans in childhood can triple the risk of brain cancer or leukemia, the study suggests.
She studied at the University of Newcastle, led by a team of medical records for approximately 180000 NHS younger patients.
But writing in The Lancet and the authors stressed that the benefits of exploration usually outweigh the risks.
They said the study sheds light on the fact that it should only be used when scans must follow the necessary forms and pieces of the radiation. During the scan (CT) CT, X-ray tube around the patient's body to produce detailed pictures of internal organs and other parts of the body.
Long-term study in the first of its kind, the researchers analyzed the medical records of patients under the age of 21 who had CT in a number of British hospitals between 1985 and 2002.
Because radiation-related cancer takes a long time to develop, we examined data from the cancer cases and deaths until 2009. Brain cancer and leukemia and rare diseases.
The study estimates that the greatest risk of lead in the case of one additional cancer of the blood and brain tumor from outside the head CT 10000 scans for children under the age of 10 years.
Said Dr. Mark Pierce, an epidemiologist at the University of Newcastle, who led the study, "We found a significant increase in risk of leukemia and brain tumors as a result of CT in childhood and adulthood early.
