ablations

Ablations is the plural of ablation, a term used primarily in medicine and science to describe the removal or destruction of tissue, material, or a surface layer.

In medicine, ablation typically refers to procedures that eliminate abnormal tissue, such as cardiac ablation to treat irregular heartbeats or tumor ablation to destroy cancerous growths.

In other contexts, ablation describes the erosion or vaporization of material, as when a spacecraft's heat shield undergoes ablation during atmospheric reentry.

The patient underwent two ablations before the arrhythmia was finally controlled.
