teenage adults and children that are translatened multiple times with computed tomography (CT), Have a small increased risk of leukemia and brain tumors in the decade following their first scan. These findings are resulting from a study of more than than 175,000 children and young adults that was led by researchers at the National Cancer Institute (NCI).
Researchers emphasize if a child should suffer a major wit injury or develop most life threatening illness, the benefits of a necessary CT scan should outweigh future cancer risks.
Despite the increase in cancer risk, these two malignancies are relatively rare and the real(a) number of actual results from radiation exposure from a CT scan is small.
Investigations have confirmed that out of every 10,000 head CT scans performed on children 10 years old or younger, one case of leukemia and one brain tumor would take place in the decade following the first CT beyond what would be expected had there not been any scans prior.
CT scans deliver a dose of ionizing radiation to the body unwrap being scanned and to nearby tissue. Low doses though can tell apart chemical bonds in DNA, that causes damage to genes that may increase a persons risk of developing cancer.
The lead author Mark S. Pearce, Ph.D.
, express CT can be highly beneficial for early(a) diagnosis, for clinical decision-making, and for saving lives. However, greater efforts should be made to undertake clinical justification and to keep doses as low as reasonably achievable, said Pearce.
