| 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. |
