Lung biopsy


Specialty of Pulmonology & respiratory medicine

A lung biopsy is the extraction of lung tissue for histological examination to determine the best diagnosis of lung diseases. The test, which usually lasts between 30 and 60 minutes, is undertaken after a period of nil by mouth, an X-ray and a CT scan of the chest. A lung biopsy is initiated through a skin incision of about 3mm, into which a needle is inserted, then into the lung tissue or tumour, from which the sample is taken for analysis in the laboratory. Subsequently, a chest radiograph is performed to verify that there has been no damage during the process.
