Doubt & Answer Explanation

Answer Explanation

Cryosurgery is the application of extreme cold to destroy abnormal or diseased tissue.

Cryosurgery works by taking advantage of the destructive force of freezing temperatures on cells. At low temperatures, ice crystals form inside the cells, which can tear them apart. More damage occurs when blood vessels supplying the diseased tissue freeze.

A common method of freezing lesions is using liquid nitrogen as the cooling solution.

Less frequently, doctors use carbon dioxide "snow" formed into a cylinder or mixed with acetone to form a slush that is applied directly to the treated tissue.

Recent advances in technology have allowed for the use of argon gas to drive ice formation using a principle known as the Joule-Thomson effect.

A mixture of dimethyl ether and propane is used in some preparations.
