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

In previous biopsies, a needle was inserted directly into the tumor tissue to extract cells and then pulled out of the body. In this way, when the needle tip is withdrawn from the body, it is easy to form a "needle passage implantation transfer".

Now, when a needle biopsy is performed, a coaxial protective coat, shaped like a ballpoint pen, is added to the outside of the needle. First, the outside pen stick is attached to the surface of the tumor to enter the tumor body to extract tumor cells. When the material is finished, return the pencil refill to the holder.

In this way, the piercing needle, like the "pen lead", although contaminated with tumor cells, is always in the protective coat similar to the "pen holder" in the process of pulling out, so as to avoid the phenomenon of "pulling up the radish and bringing out the mud".

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