Bronchoscopy
Allows direct visualization of the airways. After a numbing medication and sedation are provided, a special flexible tube is passed through the mouth or nose and into the airways where specimens can be taken, aiding in diagnosis.
Sputum Examination
With coughing, tumor cells can be released into the sputum. Collecting a morning specimen can be very helpful in detecting abnormal cells.
PET Scan
The PET scan is a diagnostic tool used to aid in the assessment of tumors. A small dose of a chemical called a radionuclide combined with a sugar is injected into a small intravenous plastic tube in the arm. Because malignant tumors grow at a faster rate than normal tissue, they take up the sugar and therefore, appear abnormal on the scan.
