What is a common use of radiofrequency ablation in clinical practice?

Radiofrequency ablation is commonly used in clinical practice primarily to destroy abnormal tissue. This technique involves using high-frequency electric energy to heat and subsequently destroy specific cells, often targeting tumors or areas of abnormal growth. The process can effectively reduce or eliminate the presence of certain conditions, such as tumors in organs like the liver, kidney, or heart, and is particularly valuable in minimally invasive procedures. By precisely targeting and destroying unwanted tissue, radiofrequency ablation can alleviate symptoms and improve patient outcomes without the need for more extensive surgical interventions.

While the other options mention important aspects of medical treatments, they do not accurately describe the main use of radiofrequency ablation. For instance, stimulating the immune system and enhancing drug delivery are not primary functions of this technology, nor is repairing damaged blood vessels, which typically involves different methods and techniques. Therefore, focusing on the destruction of abnormal tissue highlights the significance of radiofrequency ablation in therapeutic applications.
