Why is the Test Performed?
A needle lung biopsy is performed when there is an abnormal condition that is near the surface of the lung, in the lung itself, or on the chest wall. The test is usually performed to diagnose relatively large abnormalities seen on chest X-ray or CT scan. Most often, the abnormality is not believed to be accessible by other diagnostic techniques, such as bronchoscopy.
