CT scans significantly increase lifetime cancer risk
Extensive clinical and epidemiological evidence demonstrates that exposure to ionizing radiation from computed tomography (CT) scans increases lifetime cancer risk, with younger patients and females facing the highest relative risks.
The retrieved papers consistently report that diagnostic CT scans expose patients to ionizing radiation doses capable of increasing lifetime cancer risk, particularly for vulnerable populations such as children and young women. Multiple large-scale epidemiological studies, risk-modeling analyses, and cohort investigations (e.g., [2], [3], [4], [5]) establish a dose-response relationship and project quantifiable excess cancer risks. No papers refute the premise that CT radiation carries a theoretical or estimated risk, though many emphasize that these risks must be weighed against the substantial immediate diagnostic benefits.
