Cryosurgery is best described as?

Explanation:
Cryosurgery works by destroying tissue with extreme cold. Cold temperatures freeze cells, form ice crystals, disrupt cell membranes, and cut off blood flow, leading to cell death in the targeted area. That combination of freezing and vascular injury is what makes the tissue sag or die, allowing doctors to treat abnormal growths or lesions with minimal damage to surrounding areas. This is why the description that fits best is destruction of tissue by extreme cold. Descriptions involving heat to destroy tissue refer to thermotherapy, mechanical removal means physically taking tissue out, and radiation therapy uses ionizing radiation to damage DNA—not freezing.
