Radiofrequency Ablation Therapy (RFA)
Radiofrequency Ablation Therapy (RFA) is performed in conjunction with
an upper endoscopy procedure and is recommended for patients with confirmed
high-grade dysplasia (advanced pre-cancerous cells). The pre-cancerous
tissue is heated to destroy the diseased tissue in a highly controlled
manner. The preparation is similar to having an upper endoscopy procedure (EGD).
