Pulmonary nodules are very common - about half of all people who get chest X-rays or CT scans have them. These are areas where lung tissue appears denser than normal, showing up as white spots or shadows on imaging. While finding a nodule might feel scary, it's important to know that more than 95% of lung nodules are not cancerous.

Most nodules are small (between 0.2 and 1.2 centimeters) and don't cause any symptoms, especially if they're small. They're often discovered accidentally during routine scans or when checking other symptoms. If your doctor finds a nodule, they'll likely monitor it with repeat CT scans every six months to a year to watch for any changes in size or shape. If there are concerns, they may recommend additional testing like a PET scan or biopsy to determine if it's cancerous. Common causes of benign nodules include scar tissue, previous infections, or small areas of inflammation called granulomas.
