Ablation is a medical procedure that involves the removal or destruction of tissue, typically with the goal of treating or removing abnormal or diseased tissue. It is often used to treat conditions such as certain types of cancers, abnormal heart rhythms, and benign tumors. Ablation can be performed using various techniques, such as heat (radiofrequency ablation), cold (cryoablation), or high-energy beams (laser ablation). The procedure is usually minimally invasive and can often be done on an outpatient basis. Ablation is considered a safe and effective treatment option for many conditions and can offer patients a less invasive alternative to surgery.
