The most common cause of cancerous or malignant lung nodules includes lung cancer or cancer from other regions of the body that has spread to the lungs ( metastatic cancer). The most common causes of benign nodules include granulomas (clumps of inflamed tissue) and hamartomas (benign lung tumors). Lung nodules can be either benign (noncancerous) or malignant (cancer). The pulmonary nodule clinic at UT Southwestern streamlines the evaluation and management of patients with pulmonary nodules and abnormal findings on imaging, including screening CT scan.
Our surgeons work closely with UT Southwestern’s interventional pulmonary team, oncologists, radiologists, and pathologists to deliver comprehensive care – all in one location, and usually on the same day.
We feature the latest imaging techniques and treatments through our advanced imaging center, including endobronchial ultrasound (EBUS), electromagnetic navigational bronchoscopy (ENB), and many other techniques. The thoracic surgeons and interventional pulmonologists at UT Southwestern Medical Center perform leading-edge procedures to evaluate and treat pulmonary nodules and various lung lesions – including bronchoscopic procedures, image-guided sampling, conventional surgical procedures, and more advanced minimally invasive and robotic techniques. Roughly half of people who smoke over the age of 50 will have nodules on a CT scan of their chest. Lung nodules are being recognized more frequently with the wider application of CT screening for lung cancer. Lung nodules are quite common and are found on one in 500 chest X-rays and one in 100 CT scans of the chest. Lesions larger than 3 cm are considered masses and are treated as cancerous until proven otherwise. A solitary pulmonary nodule or “spot on the lung” is defined as a discrete, well-defined, rounded opacity less than or equal to 3 cm (1.5 inches) in diameter that is completely surrounded by lung tissue, does not touch the root of the lung or mediastinum, and is not associated with enlarged lymph nodes, collapsed lung, or pleural effusion.Ī pulmonary nodule can be benign or cancerous.
