Michigan Early Disease Progression Cohort

Participants between the ages of 30-55 with at least 10 pack-year smoking history will be enrolled into a observational longitudinal cohort. During the course of the study, additional funding was secured, so data could be collected for a 3-year period from participants. Some of the cohort are co-enrolled in another study (NCT05033990) where they received a CT scan as part of the study. Those participants will not be re-scanned during the course of this study.
