why is helium so used incryosurgery
Answers
Helium is inert because the outer valence shell is completely filled with electrons; helium therefore does not have the capacity to interact with other atoms. In cryotherapy as a prostate cancer treatment, helium is the gas used for facilitated thawing.

: The branch of surgery applying cryogenic temperatures to ... Liquefied gases, such as liquid nitrogen and liquid helium, are used in many ... to transmit power by overhead cables, so underground cables are used.
Explanation:
The repulsive forces in helium and hydrogen outweigh the sticking forces, resulting in heating instead of cooling, as described for the other gases. In cryotherapy, the application of this principle with gases with different Joule-Thomson behaviors offers the opportunity to clinically freeze or thaw tissues
Cryosurgery (also called cryotherapy) is the use of extreme cold produced by liquid nitrogen (or argon gas) to destroy abnormal tissue. Cryosurgery is used to treat external tumors, such as those on the skin
