A Prospective, Two-center, Single Arm Phase II Clinical Study to Evaluate Safety and Effectiveness of Ablation Therapy in the Treatment of Lung Cancer Presenting as Ground-glass Nodules

This study evaluates a minimally invasive treatment called ablation therapy (using heat or cold to destroy tissue) for small lung abnormalities called ground-glass nodules (GGNs) — hazy areas seen on CT scans that may be early lung cancer — in patients who cannot have or choose not to have surgery. **You may be eligible if...** - You are between 18 and 85 years old - A CT scan shows a ground-glass nodule in your lung that has not resolved after 3 months - The nodule is between 8mm and 3cm in size - The nodule has shown growth or increased density over time - You cannot tolerate standard surgery, have multiple nodules, or have already had surgery on the same side of the chest **You may NOT be eligible if...** - You have been in another clinical trial within the past month - You have severe other illnesses - You have an allergy to anesthesia drugs - You have another autoimmune disease - You cannot cooperate with the research team Talk to your doctor to see if this trial is right for you.
