Is electrosurgery done with an electrosurgical unit?

The unit produces energy that can cut tissue, seal small blood vessels or destroy targeted superficial tissue, depending on the electrode and setting. The clinician selects the technique according to the lesion, location and intended result. A return electrode may be used with some systems to complete the electrical circuit.

Electrosurgery is not a single procedure. It may be used for selected benign lesions or other dermatology treatments after examination, and a suspicious lesion may need a different approach so it can be assessed properly.

Ask what is being treated, whether a sample is needed, and which energy method will be used. Tell the clinician about implanted electrical devices, medicines that affect bleeding, metal allergies and conditions that may change healing. Follow instructions for keeping the site clean and protected afterward.

Contact the clinic for bleeding that does not settle with firm gentle pressure, increasing pain, spreading redness, warmth, pus or fever. Seek urgent care for severe swelling, breathing difficulty, chest symptoms or a rapidly worsening reaction.

What is the diagnosis and treatment goal? Will tissue be sent for examination? Which device setting and aftercare plan fit this site, and what signs should prompt an earlier review?
