Cancer Risk to Children Is Found in CT Scans
New York Times

CT scans in children can cause small but significant increases in the risk of leukemia and brain cancer, a new study finds. Researchers say the results do not mean that CT scans should be avoided entirely — they can be vitally important in certain situations, like diagnosing severe head injuries — but that the test should be performed only when necessary, and with the lowest possible dose of radiation. CT, or computed tomography, scans take X-rays from various angles and combine them to create cross-sectional images, and they involve much more radiation than traditional X-ray techniques.
