"Ours is the first population-based study to capture data on every CT scan to an individual during childhood or young adulthood and then measure the subsequent cancer risk." Despite the elevation in cancer risk, these two malignancies are relatively rare and the actual number of additional cases...
Moreover, cancer risks elevated with increase of radiation dose (OR, 33.31 [95% CI, 21.33 to 52.02]), and multiple CT scan sites (OR, 14.08 [95% CI, 6.60 to 30.05]). The risk of solid malignancy was higher than leukemia. Notably, there were no significant differences for age, gender...
CT scans in cancer fears New evidence of a "substantial cancer risk" from CT scans is reported in the Lancet Oncology in October. At Columbia University researchers have calculated that the radiation produced from an annual scan, risks a one in fifty chance of death. "The risks of full ...
(HealthDay)—Doctors routinely order CT scans as diagnostic tools. But many are ill-informed about the cancer risks associated with this imaging technology, a new study suggests.
CT scans are super-sharp X-rays that have transformed medicine by helping doctors quickly diagnose or rule out injuries and diseases. But they use far more radiation than ordinary X-rays, and too much radiation raises the risk of cancer over time. ...
Our objective was to estimate the cancer risk related to childhood CT scans, and examine how cancer-predisposing factors (PFs) affect assessment of the radiation-related risk. The cohort included 67274 children who had a first scan before the age of 10 years from 2000 to 2010 in 23 French ...

CT Scans and Lung Cancer Small or slow-growing nodules (小结节) discovered on a lung scan are unlikely to develop into tumors over the next two years, researchers reported on Wednesday. The findings reported in the New England Journal of Medicine, could help doctors decide when to do more ...
CT scan is a life-saving medical diagnostic tool, entailing higher levels of ionising radiation exposure than conventional radiography, which may result in an increase in cancer risk, particularly in children. Information about the use and potential health effects of CT scan imaging among young peopl...
