Does lung cancer puncture needle check have risk

For peripheral lung cancer, as it is located at the end of the bronchial tree, the bronchoscopy is often not effective, and the sputum examination of cancer cells is often 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. Puncture examination is generally safe, but there are still certain risks. Dyspnea and pneumothorax should be prevented during puncture. If the lesion is peripheral type, it is safer. If it is central type, the risk is relatively higher because it is close to the heart and large blood vessels. 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, and currently the puncture needle used for lung puncture is mostly trocar, that is, there is a cannula outside the needle, and the cannula immediately encloses the biopsy needle including the biopsy tissue after obtaining the biopsy tissue. Therefore, the incidence of in-vitro metastasis has been greatly reduced.
