A recent study published in JAMA Internal Medicine estimates that CT scans performed in 2023 could contribute to more than 103,000 future cancer cases in the U.S.—accounting for about 5% of all annual cancer diagnoses.
Key Findings:
Over 93 million CT scans were conducted last year
Abdominal and pelvic scans posed the highest cancer risk
Children and older adults are especially vulnerable
While CT scans remain a vital diagnostic tool, researchers urge more cautious and judicious use, emphasizing the importance of informed decision-making by both physicians and patients. In many cases, safer imaging alternatives may be available.
