Can a patient with lung cancer undergo a lung puncture needle biopsy? Will it cause cancer cells to spread?

 For space-occupying lesions in the lung, percutaneous lung puncture can be considered when lung cancer is suspected. The needle for percutaneous lung puncture is very thin. Generally, a 16G or even 18G biopsy gun is used. The puncture is relatively safe, and the possibility of spreading from the needle path is very small. If it is really lung cancer, the patient will hardly die from the needle path caused by percutaneous puncture. Spread. Because peripheral lung cancer is very close to the chest wall, it is almost impossible to obtain tissue by bronchoscopy. Therefore, percutaneous lung puncture is often used for the diagnosis of lung cancer. Even if lung cancer is diagnosed by other tests, in order to clarify its histological type and facilitate chemotherapy, it is also done Skin-pulmonary puncture; 2. The requirement of percutaneous pulmonary puncture is not high. As long as the patient does not have severe emphysema, the blood coagulation function is not serious, and the puncture site is not infected, almost everything can be done.
