This study is mapping and characterizing the cells found in the lung's air sacs (alveoli) in people with and without smoking history and COPD. Researchers are collecting tissue during planned lung surgery to better understand how smoking and COPD change the cells at the molecular level. **You may be eligible if...** - You are 18 or older - You are already scheduled to have lung resection surgery (lobectomy, pneumonectomy, or segmentectomy) for cancer or suspected cancer - You are affiliated with a French social security plan **You may NOT be eligible if...** - You have a chronic autoimmune disease - You received chemotherapy before your surgery - You have had prior chest radiation therapy - You are under legal guardianship Talk to your doctor to see if this trial is right for you.
