Lung needle biopsy
A lung needle biopsy is a method to remove a piece of lung tissue for examination. If it is done through the wall of your chest, it is called a transthoracic lung biopsy.
How the Test is Performed
The procedure usually takes 30 to 60 minutes. The biopsy is done in the following way:
- A chest x-ray or chest CT scan may be used to find the exact spot for the biopsy. If the biopsy is done using a CT scan, you may be lying down during the exam.
Chest x-ray
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.

- You sit with your arms resting forward on a table. Your skin where the biopsy needle is inserted is scrubbed.
- A local painkilling medicine (anesthetic) is injected.
- The doctor makes a small cut in your skin.
- The biopsy needle is inserted into the abnormal tissue, tumor, or lung tissue. A small piece of tissue is removed with the needle.
Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).

- A chest x-ray is taken right after the biopsy.
- The biopsy sample is sent to the lab. Analysis usually takes a few days.
How to Prepare for the Test
You should not eat for 6 to 12 hours before the test. Follow instructions about not taking nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, or blood thinners such as warfarin for a period of time before the procedure. Check with your health care provider before changing or stopping any medicines.
Before a needle biopsy of the lung, a chest x-ray or chest CT scan may be performed.
How the Test will Feel
You will receive an injection of anesthetic before the biopsy. This injection will sting for a moment. You will feel pressure and a brief, sharp pain when the biopsy needle touches the lung.
Why the Test is Performed
A lung needle biopsy is done when there is an abnormal condition near the surface of the lung, in the lung itself, or on the chest wall. Most often, it is done to check for cancer. The biopsy is usually done after abnormalities appear on a chest x-ray or CT scan. Sometimes your doctor might recommend a bronchoscopy instead of lung needle biopsy depending on the location of the abnormality.
Normal Results
In a normal test, the tissues are normal and there is no cancer or growth of bacteria, viruses, or fungi if a culture is performed.
What Abnormal Results Mean
An abnormal result may be due to any of the following:
- Bacterial, viral, or fungal lung infection
- Cancerous cells (lung cancer, mesothelioma)

Risks
Sometimes, a collapsed lung (pneumothorax) occurs after this test. A chest x-ray will be done to check for this. The risk is higher if you have certain lung diseases such as emphysema. Usually, a collapsed lung after a biopsy does not need treatment. But if the pneumothorax is large, there is preexisting lung disease or it does not improve, a chest tube is inserted to expand your lung.
Pneumothorax
A collapsed lung occurs when air escapes from the lung. The air then fills the space outside of the lung between the lung and chest wall. This buil...

Whenever a biopsy is done, there is a risk of too much bleeding (hemorrhage). Some bleeding is common, and a provider will monitor the amount of bleeding. In rare cases, major and life-threatening bleeding can occur.
A needle biopsy should not be performed if other tests show that you have:
- Bleeding disorder of any type
- Bullae (enlarged alveoli that occur with emphysema)
- Cor pulmonale (condition that causes the right side of the heart to fail)
