Endoscopic procedures

An endoscopic procedure may be done to diagnose and stage non–small lung cancer (NSCLC). It allows a doctor to look inside body cavities using a flexible tube with a light and lens on the end (an endoscope). Endoscopic procedures used to diagnose and stage lung cancer include:

   bronchoscopy
       A bronchoscopy may be done to look for a tumour inside the bronchi.
       During a bronchoscopy, the doctor may remove a sample of tissue or fluid to be examined under a microscope to diagnose non–small lung cancer.
   mediastinoscopy or mediastinotomy
       A mediastinoscopy may be done to look at the mediastinum
       mediastinum
       The space in the chest between the lungs, breastbone and spine that contains the heart, great blood vessels, thymus, trachea (windpipe), esophagus and lymph nodes. and get samples of tissues in the area.
       A mediastinotomy is similar to mediastinoscopy. Instead of inserting an endoscope through a cut in the neck, the doctor makes a slightly larger incision between the ribs. This allows the doctor to examine lymph nodes that cannot be reached by a mediastinoscopy.
   thoracoscopy (pleuroscopy)
       A thoracoscopy may be done to look at and sample tissue from the chest wall, mediastinum, outer lining of the lungs (pleura) and lymph nodes in the chest.
       Thoracoscopy is not often done to diagnose lung cancer. It may be used if other tests, such as bronchoscopy, cannot get enough tissue to make a diagnosis.
