Lung nodules choice needle biopsy or direct surgery is better

Needle biopsy is a long and thin needle in the doctor's hand that punctures the site of the lung mass under CT or ultrasound localization to obtain some tissues inside the mass for pathological examination. Different from the puncture biopsy of other organs, the lung is an organ continuously active due to respiration. In the process of respiration, the lung tissue rises and falls, and the tumor also rises and falls, and the position is not fixed, so not every puncture can penetrate the tissue inside the tumor. For some patients, due to the location and morphology of the lesion, the diagnosis can not be completely confirmed. The accuracy rate of needle biopsy is about 80%-90%. There are certain risks associated with needle biopsy: pneumothorax, bleeding, infection, etc. The problems that need to be considered in needle biopsy also include: the failure to detect cancer cells can not completely exclude lung cancer, which may cause delay of disease; If the nodules are malignant, there is a potential risk of implantation metastasis by puncture.
