Which treatment uses extreme cold to destroy abnormal tissue?

Cryoablation Cryotherapy Thermal ablation Laser ablation

Correct Answer:

Cryoablation

Explanation:

Extreme cold is used in cryoablation to destroy abnormal tissue. The freezing process forms ice crystals inside cells and damages cellular membranes and the surrounding blood vessels, leading to cell death. By applying controlled freezing and thawing, the targeted tissue is ablated while nearby healthy tissue can be spared with careful technique. Cryotherapy is a broader cold-based approach that isn’t always aimed at definitive ablation. In contrast, thermal and laser ablation rely on heat or light energy, not cold, to destroy tissue.
