Former Smokers May Merit Later Screening

Cohort data suggest past-eligible former smokers retain competing mortality profiles similar to younger current-eligible smokers

1

Former smokers who quit over 10 years ago still show elevated lung cancer and other-cause mortality, questioning current screening eligibility criteria.
2

The study analyzed 24,715 participants, revealing that former smokers' mortality risk varies significantly based on age at cessation.
3

Lung cancer mortality does not decrease with longer cessation times, indicating persistent biological risk after substantial cumulative exposure.
4

Findings suggest that former smokers who previously met screening criteria may still warrant consideration for lung cancer screening.
5

The study's observational nature and limitations highlight the need for larger studies to assess the impact of modifying screening age limits.
