Overuse of CT Scans Could Cause Over 100,000 Cancer Cases in the US
2025-04-15
A new study reveals that the 93 million CT scans performed in the US in 2023 could lead to over 100,000 cancer cases, including nearly 10,000 in children. This accounts for 5% of all US cancers, equivalent to alcohol-induced cancers. Researchers urge reducing unnecessary scans and optimizing radiation doses to mitigate cancer risk. While CT scans are crucial for diagnosis and treatment, overuse increases radiation exposure and cancer risk. The study emphasizes the importance of clinically justified scans with age and organ-specific dose adjustments.
