Patient-derived Organoid Model and Circulating Tumor Cells for Treatment Response of Lung Cancer

This trial is collecting tumor and blood samples from people with lung cancer to grow miniature replicas of the tumor in the lab (called organoids) and to look for cancer cells circulating in the blood, so researchers can predict which treatments will work best for each patient. **You may be eligible if...** - You have been diagnosed with lung cancer or have a suspicious lung mass or swollen lymph nodes being evaluated - You are scheduled to receive standard treatment (either systemic therapy or surgery) - You are at any stage of lung cancer - You have read and signed the informed consent form **You may NOT be eligible if...** - You are unable or unwilling to provide consent - A tissue sample cannot safely be collected from your tumor - You are not scheduled for any standard treatment Talk to your doctor to see if this trial is right for you.
