University of Michigan COPD Identification Through Lung Cancer Screening Cohort Study - MAP2

This study is building a research group (cohort) of current or former smokers who qualify for lung cancer screening and also have evidence of COPD (chronic obstructive pulmonary disease — a serious lung condition that makes it hard to breathe). The aim is to better understand COPD in this population and improve future screening and treatment strategies. **You may be eligible if...** - You are aged 50–80, currently smoke or smoked for at least 20 pack-years - You had a lung cancer screening CT scan at the University of Michigan within the past year - You have a prior COPD diagnosis, previous lung function test confirming COPD, or evidence of emphysema on your CT scan - You are willing to be contacted for future studies **You may NOT be eligible if...** - You have another major respiratory condition (other than COPD or asthma) causing your breathing symptoms - You have severe asthma requiring high-dose medications or frequent hospitalizations - Your BMI is over 35 - You are currently pregnant - You use illicit substances, including cannabis smoking - You have had thoracic (chest) radiation or surgery removing lung tissue - You have an illness expected to cause death within 3 years - You had a COPD flare-up or are on antibiotics/steroids in the past 30 days (you can reapply later) Talk to your doctor to see if this trial is right for you.
