Does tumour do puncture needle meet tumour spread?

A large number of studies at home and abroad have proved that this probability is very small, if appropriate protection measures are used in the process of operation, the probability of transfer is completely negligible.

Previously, a needle was inserted directly into the tumor tissue to extract cells and then pulled out of the body. In this way, when the tip exits in vitro, it is easy to form "needle planting transfer".

Today, when a needle is biopsied, a coaxial sheath is placed over the needle, shaped like a ballpoint pen. First, the outside pen stick to the surface of the tumor, in order to enter the tumor body to extract tumor cells. When the material is finished, return the pen lead to the pen holder.

In this way, the needle, which looks like a "pen tip," is contaminated with tumor cells, but it is always in a protective coat like a "pen holder" during the process of being pulled out, so as to avoid the phenomenon of "pulling out the carrot and bringing out mud."

Therefore, the puncture will not cause the tumor to spread.
