Answer:
The method that uses extreme cold to destroy unwanted tissue is called cryotherapy. Cryotherapy involves the application of freezing temperatures to targeted areas of the body to remove or treat abnormal or unwanted tissue. It is commonly used in medical procedures to remove skin lesions, warts, and other unwanted growths. During cryotherapy, a freezing agent such as liquid nitrogen is applied to the affected area, causing the tissue to freeze and eventually die. The frozen tissue will then be naturally eliminated by the body's immune system or may require subsequent removal. Cryotherapy is a relatively quick and minimally invasive procedure that is generally well-tolerated by patients.
