What is a tag on the lungs?

A "tag" on the lungs typically refers to a small, benign growth or nodule, often identified during imaging studies like X-rays or CT scans. These tags are usually non-cancerous and may represent scar tissue or other harmless formations. However, further evaluation is often necessary to rule out any serious conditions, especially if there are changes in size or appearance over time. It's important to consult a healthcare professional for proper diagnosis and management.
