Lung nodules are small, round or oval growths in the lungs that are commonly detected on imaging studies such as chest X-rays or CT scans. While many lung nodules are benign, some may be early signs of lung cancer or other serious conditions. Research in this area focuses on improving the detection and diagnosis of lung nodules, developing guidelines for management and follow-up of nodules, and investigating new treatments for lung nodules that are cancerous. Additionally, researchers are exploring the use of advanced imaging techniques, biomarkers, and genetic testing to better characterize lung nodules and improve outcomes for patients.
