Is lung cancer biopsy risky?

For peripheral lung cancer, because it is located at the terminal end of the bronchial tree, the results of bronchoscopy are often not good, and the sputum examination for cancer cells is often negative. Diagnosed metastases require biopsy by percutaneous lung aspiration. Pathological examination after puncture of lung cancer can be used to determine benign and malignant. The puncture examination is generally safe, but there are still certain risks. During the puncture process, dyspnea and pneumothorax should be prevented. If the lesion is a peripheral type, it is relatively safe, and if it is a central type, the risk is relatively higher due to its proximity to the heart and large blood vessels. Although lung cancer puncture examination has the possibility of puncture tract implantation in theory, in clinical practice, the probability of lung cancer metastasis and spread caused by lung puncture is very small, and most of the puncture needles used for lung puncture are trocars, that is, there is a sleeve outside the needle. After the biopsy tissue is obtained, the cannula closes the biopsy needle including the biopsy tissue immediately, so the incidence of metastases along the way during removal from the body 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 whether there are risks in lung cancer puncture examination. I hope it can be helpful to everyone.
