How does the lymph node biopsy needle work? How harmful is it to the human body?

There are generally two methods for lymph node biopsy: one is to use puncture to check, without using anesthesia, and only use a syringe to extract an appropriate amount of tissue from the local area for pathological examination. The positive rate of the test will increase. This method is simple and quick, has no effect on the body, and has little irritation to the tissue, but there is a certain false negative rate, which means that it may not be possible; another method is to cut Lymph nodes are sliced. Because the whole tissue is taken, the diagnosis rate is extremely high. Generally, it will not cause any irritation to the body, nor will it cause any impact. However, because of the need for surgery (minor surgery), there is a certain amount of pain. It will also increase the cost. I personally suggest that the latter is more reliable. The specific plan is still up to you to weigh it!
