What are the risks of lung biopsy and can it cause metastasis?

The gold standard for the diagnosis of lung cancer is pathological diagnosis. There are various methods to obtain pathological diagnosis, the most commonly used is needle biopsy. Puncture biopsy of lung tumors can be divided into the following two methods: 1. Biopsy of mass tissue under bronchoscope to determine its pathological type, which is most suitable for central lung cancer; 2. 2. Under the guidance of CT, the puncture needle is inserted into the tumor, and then the tumor tissue section is taken for examination to confirm the diagnosis. This method is suitable for tumors located around the lung. In addition, if the location of the tumor is close to the pleura and the mass is large, ultrasound-guided puncture biopsy can be performed to confirm the diagnosis.
