What is a needle biopsy?

Needle biopsy is a type of biopsy. Biopsy is also called pathological examination. It is one of the commonly used examination methods in medicine and can provide the most reliable scientific basis for diagnosis.

But doctors often say that pathology is the gold standard for diagnosis. It is a mule or a horse.

Let's take moon cakes as a simple analogy:

The moon cake does not know what filling it is from the outside. If you use a toothpick to pierce the moon cake and see that there is no egg yolk on the toothpick after pulling it out, you can tell that the moon cake is not filled with egg yolk. clear. Then insert the chopsticks with grooves in the front section into the moon cake and pull it out. A very small amount of moon cake filling will be taken out from the groove, so you can know whether the moon cake has egg yolk, and whether it has lotus seed paste or five kernels.

If the chopsticks are put into a straw, the straw is connected to negative pressure, so that the small amount of moon cake filling is sucked out through the straw again and again, so that a straw can be inserted to suck out the moon cake filling many times, and more moon cake filling can be obtained to confirm the moon cake. what stuffing.

In needle biopsy, fine needle aspiration is like a toothpick, only the cells of the tumor can be penetrated, and the benign or malignant tumor can be judged according to the cells. Core needle puncture is like chopsticks with grooves, which can obtain a very small amount of tumor tissue, and multiple punctures can obtain enough specimens. The vacuum-assisted rotary biopsy system is like chopsticks with a straw, and a sufficient amount of tumor tissue can be obtained in one entry for pathological examination.
