Is Lung Cancer Needle Biopsy Examination Risky

For peripheral lung cancer, due to its position at the end of the bronchial tree, the bronchoscopy is often not effective, and the sputum examination of cancer cells will often be negative. If there is no metastasis easy to obtain pathological diagnosis such as pleural effusion and supraclavicular enlarged lymph nodes at this time, percutaneous lung puncture examination is needed to obtain biopsy. The benign and malignant lung cancer can be determined by pathological examination after puncture needle. Puncture needle examination is generally safe, but there are still certain risks. Dyspnea and pneumothorax should be prevented during the puncture process. If the lesion is peripheral type is relatively safe, if it is central type, because it is close to the heart and large blood vessels, the risk is relatively higher. Although puncture canal implantation is theoretically possible for lung cancer puncture examination, the probability of lung cancer metastasis and diffusion caused by lung puncture is very small in clinical practice. At present, the puncture needle used for lung puncture is mostly trocar, that is, there is a cannula outside the needle. After obtaining the biopsy needle tissue, the cannula will immediately close the biopsy needle including the biopsy tissue. Therefore, the incidence of in-vitro metastasis has been greatly reduced. The above content is an introduction to the risk related issues of lung cancer puncture examination. I believe that after reading it, you have a certain understanding of the risk of lung cancer puncture examination
