Yan Leyfman: How many future cancers could be linked to CT scans in the U.S.

Yan Leyfman, Co-founder and executive director of MedNews Week, shared an article by Rebecca Smith-Bindman et al, on X:

“How many future cancers could be linked to CT scans in the U.S.?

A recent risk model projects that 93 million CT exams performed in 62 million patients in 2023 may lead to ~103,000 future cancers.

Key findings:

  • Children face higher risk per scan, but adults account for most cases due to higher scan volume.
  • Lung, colon, leukemia, bladder, and breast (in females) were the most common projected cancers.
  • CT scans of the abdomen/pelvis and chest contributed the most to projected risk.

If current practices continue, CT-associated cancers could make up ~5% of all annual cancer diagnoses.”
