How is the Test Performed?
-
A chest X-ray or chest CT scan may be used to locate the precise spot of the biopsy. (If the biopsy is done using a CT scan, you may be lying down during the exam.)
-
You sit with your arms resting forward on a table. You should maintain this position and refrain from coughing during the biopsy. The skin is scrubbed and a local anesthetic is injected.
-
A small (about 1/8-inch) incision may be made in the skin, and the biopsy needle is inserted into the abnormal tissue, tumor, or lung tissue. A small specimen is removed with the needle and sent to the laboratory.
-
Pressure is placed over the site. Once bleeding has stopped, a bandage is applied.
-
A chest X-ray is obtained immediately after the biopsy.
The procedure usually takes 30 to 60 minutes. Laboratory analysis usually takes a few days.
