Final answer:
Very low temperatures for tissue destruction are used in cryotherapy, which employs cryogenic liquids like liquid nitrogen to freeze and thereby destroy targeted tissues with minimal blood loss.
Step-by-step explanation:
Very low temperatures are used in cryotherapy to destroy tissue by freezing it on contact. This specialized type of surgery utilizes the extreme cold produced by cryogenic liquids such as liquid nitrogen to selectively target and destroy diseased or overgrown tissues.
The technique is highly effective with minimal blood loss. Unlike cryotherapy, electrocautery uses electric current to heat tissue for destruction, laser surgery employs focused light, and chemotherapy involves chemical substances to treat diseases like cancer.
