Low-dose CT: who should and shouldn’t
Annual LDCT lung-cancer screening for everyone? The evidence only supports high-risk groups.
- 1USPSTF 2021: aged 50–80, ≥20 pack-years, current smoker or quit <15 years → yearly
- 2NLST: in heavy smokers, LDCT cut lung-cancer mortality by 20% (relative)
- 3The cost: 24% of scans positive, 96% of those turn out not to be cancer
- 4Overdiagnosis is about 18% of detected cancers
- 5Never-smokers without family history: no randomised trial shows lower mortality
- 6LDCT uses no contrast — no direct effect on kidney function
Taiwan’s public programme also covers family history — check the Health Promotion Administration for criteria. Quitting beats any screening.

| 0–5 | CT scanner | Should you get a low-dose CT every year? |
| 5–25 | USPSTF criteria | US guidance: aged 50 to 80, 20 pack-years, still smoking or quit under 15 years ago — once a year. |
| 25–45 | 24% positive → 96% false | NLST cut lung-cancer deaths by 20%, but a quarter of scans were positive and 96% of those were not cancer. |
| 45–60 | Never-smoker question mark | For never-smokers, no randomised trial shows yearly LDCT helps. Family history? Talk to your doctor. |
