11 Ιαν 2019 · The use of computed tomography (CT) scans for medical imaging has skyrocketed in recent years, most significantly in the United States, and scientists have sought to determine whether the resulting radiation exposure in children can increase their risk of developing brain tumors later in life.
The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose.
The age-specific impact of radiation is well documented 5–12; for example, the estimated attributable risk of death from cancer from a single head CT is highest for the youngest patients 5,6,31 and rapidly declines after 20 years of age. 6 The highest risks were observed in children less than 5 years of age and appear to be exponentially ...
9 Νοε 2023 · Our results strengthen the body of evidence of increased cancer risk at low radiation doses and highlight the need for continued justification of pediatric CT examinations and...
18 Ιουλ 2018 · We found evidence that CT-related radiation exposure increases brain tumor risk. No association was observed for leukemia. Compared with the general population, incidence of brain tumors was higher in the cohort of children with CT scans, requiring cautious interpretation of the findings.
6 Δεκ 2022 · The European EPI-CT study aims to quantify cancer risks from CT examinations of children and young adults. Here, we assess the risk of brain cancer. Methods. We pooled data from nine European countries for this cohort study.
Exposure to ionizing CT scans during childhood or adolescence was shown to increase the risks of developing leukemia, brain cancer, and other cancers (13,21). Our study reveals the potential risk of adulthood medical radiation exposure in the development of thyroid cancer, leukemia, and NHL.
