**Question:** Radiofrequency ablation is done for-

A. Pain management
B. Tumour ablation
C. Cardiac arrhythmias
D. Obesity treatment

**Correct Answer:** B. Tumour ablation

**Core Concept:** Radiofrequency ablation (RFA) is a minimally invasive medical procedure used for thermal ablation therapy, where heat is generated using radiofrequency (RF) waves to destroy targeted tissues. This is mainly applied to treat various pathological conditions by selectively damaging cells while minimizing damage to surrounding healthy tissue. RFA is commonly used in interventional radiology, cardiology, and oncology.

**Why the Correct Answer is Right:** Radiofrequency ablation is primarily used for tumour ablation because it allows targeted destruction of cancerous cells while minimizing damage to healthy surrounding tissue. The heat generated from RF waves is specific enough to destroy cancer cells but not healthy cells.

**Why Each Wrong Option is Incorrect:**

A. Pain management: While RFA can be used for pain management, it is not the primary application of this technique. Other pain management methods, such as nerve blocks or spinal cord stimulation, are more commonly used.

B. Obesity treatment: Radiofrequency ablation is not used for obesity treatment. More appropriate methods include bariatric surgery or lifestyle modifications like diet and exercise.

C. Cardiac arrhythmias: Radiofrequency ablation is used in interventional cardiology to treat various cardiac arrhythmias (abnormal heart rhythms) by destroying specific areas of the heart tissue involved in the arrhythmia. However, this option is not the primary target of RFA.

**Clinical Pearl:** Radiofrequency ablation is a valuable tool in various medical specialties, including interventional radiology, cardiology, and oncology. Understanding the appropriate application of this technique ensures optimal patient outcomes and minimizes potential complications.
