Fulguration is a biopsy procedure that uses what technique?

1. Ultrasound waves

2. Electric sparks controlled by a moving electrode

3. Chemotherapy agents

4. Laser technology

The correct answer is: Electric sparks controlled by a moving electrode

Fulguration is a technique that involves using electric sparks controlled by a moving electrode to destroy tissue. This method is often employed for removing or treating abnormal cells or tissues, particularly in the context of tumors. The electrical energy generates heat, which in turn leads to the destruction of the targeted tissue, making it an effective approach in various medical procedures, including certain types of biopsies and surgical interventions. The other options, while relevant in their own contexts, do not accurately describe the method used in fulguration. Ultrasound waves are utilized in procedures like ultrasound-guided biopsies but not in fulguration. Chemotherapy agents are medications used for systemic treatment of cancer but do not involve direct tumor destruction using an electrical technique. Laser technology also serves as a method to cut or destroy tissue but operates on different principles and is distinct from the electric spark technique employed in fulguration.
