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.
11 Ιαν 2019 · Radiation exposure from CT scans in childhood and subsequent risk of leukemia and brain tumors: a retrospective cohort study. Cancer risk in 680,000 people exposed to computed tomography scans in childhood or adolescence: data linkage study of 11 million Australians.
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 ...
18 Ιουλ 2018 · For a nationwide retrospective cohort of 168 394 children who received one or more CT scans in a Dutch hospital between 1979 and 2012 who were younger than age 18 years, we obtained cancer incidence, vital status, and confounder information by record linkage with external registries.
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...
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.
10 Οκτ 2021 · 20 years ago a trio of manuscripts describing the dose levels and potential cancer risks from CT scans in children raised awareness of a growing public health problem. 1–3 Within months of these publications, plans were underway for the first epidemiological studies to investigate the potential risks.
