Missing Millions · 2026 estimate

11.9 million Americans are missing their lung cancer screening.

They qualify. They haven't been screened. Low-dose CT finds lung cancer early, when it is most treatable. See the gap where you live, then share it.

14.5 millionadults qualify for screening under USPSTF 2021 criteria: ages 50 to 80, 20+ pack-years, smoke now or quit within 15 years
18.2%of eligible adults were screened nationally (American Lung Association, 2025)
1 in 9adults ages 50 to 80 qualifies for screening and hasn't been screened (estimate)

Methodology

How we estimate the gap

These are modeled estimates built entirely from public data. They are not counts of individual people and contain no patient information.

Step 1

Adults ages 50 to 80

County population ages 50 to 79, plus one fifth of ages 80 to 84.

U.S. Census Bureau, Population Estimates, Vintage 2025

Step 2

Local smoking rate

County current cigarette smoking, modeled by CDC PLACES from BRFSS survey data.

CDC PLACES 2025 release; Kentucky and Pennsylvania use the 2024 release

Step 3

USPSTF 2021 eligibility

One national factor (0.99) covers former smokers who quit within 15 years and the share with 20+ pack-years, scaled so the U.S. total matches about 14.5 million eligible adults.

USPSTF 2021 recommendation and published national estimate

Step 4

Minus those screened

Each state's share of eligible adults who were screened is removed, leaving the estimated number missing.

American Lung Association, State of Lung Cancer 2025

missing = adults 50 to 80 × county smoking rate × 0.99 × (1 − state screening rate)

What this estimate is

  • A directional, population-level estimate for planning and awareness.
  • Built the same way for every county and state, so places can be compared.
  • Refreshed every November for Lung Cancer Awareness Month.

What it is not

  • Not a count of individual patients, and not a substitute for registry or claims data.
  • County smoking rates are modeled and less certain in small counties. Estimates under 50 are shown as "fewer than 50"; others are rounded.
  • Former-smoker and pack-year shares are applied nationally, so local smoking history differences are not fully captured.

County pages also use age from Census population estimates, language from the American Community Survey 2020 to 2024, and Medicare fee-for-service low-dose CT claims (CPT 71271, 2024) by provider location.
