It depends on the location of the biopsy, if it is a superficial lymph node biopsy and is located in the upper abdomen and neck, it can be sedentary for a long time. This is because it does not affect the local blood supply and does not cause bleeding. But if it is a kidney puncture biopsy. It is not recommended to sit for a long time, because it is easy to cause local bleeding. At the same time, if it is a lymph node biopsy located in the inguinal region, it is also not recommended to sit for a long time, because it will lead to local congestion, cause local bleeding, and cause local pain. Also, other parts of the localized biopsy are not suitable for sedentary, such as popliteal fossa biopsy, liver biopsy, pancreas biopsy and so on. Therefore, it is necessary to communicate and consult with the attending physician whether or not to be sedentary after the biopsy. It is also recommended to lie down for a short period of time after the biopsy to promote local recovery.
