What is lung biopsy?
Lung biopsy is a type of medical test that is performed to check lung tissues for pathology or cancer. The test uses imaging to locate abnormalities in the lung tissue, and then a small sample is removed for microscopic examination.
What does it consist of?
The medical test lasts 30 to 60 minutes and an imaging system can be used to visualize and identify the area chosen for biopsy. The patient sits on a table with arms outstretched, while a relaxing sedative is administered and a local pain medication is injected. A small cut is then made in the skin, through which the biopsy needle is inserted to extract a sample of lung tissue. When the procedure is completed, the needle is removed from the area, pressure is applied to the affected area and when the bleeding has stopped, a bandage is applied. At the end of the lung biopsy, a chest X-ray is taken, while the sample obtained is sent to a laboratory to analyze in detail if there is any disease or pathology.
Lung biopsy should be performed when an abnormality appears in the area close to the lung.
Why is it performed?
Lung biopsy should be performed when an abnormality appears in the area near the lung. The main function of lung biopsy is to rule out cancer. This test is performed after abnormalities appear on other tests such as a chest X-ray or CT scan.
Preparation for lung biopsy
Before contacting the specialist for the intervention, it is advisable to follow a series of tips. For example: Do not eat any food for 6 to 12 hours before the medical test. Do not take acetylsalicylic acid (aspirin), non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, or anticoagulants such as warfarin in the days prior to the medical test. If you have any doubts about taking medication, it is advisable to consult your specialist.
What will I feel during the test?
The patient will be administered anesthesia to reduce the sensation of pain. On the other hand, when the biopsy needle touches the lung, the patient will feel pressure and a strong pain that may last for a few moments.
Meaning of abnormal results
A lung biopsy with abnormal results may be considered when the following diseases or pathologies are identified: viral, bacterial or fungal lung infection, the existence of cancer cells, such as lung cancer or mesothelioma, or pneumonia.
