What is an electrosurgical unit used for?

The unit sends a selected current through an electrode or handpiece. Heat generated at the treatment point can cut tissue, destroy a small unwanted lesion, or seal small blood vessels. A clinician may also use it after curettage to treat the base of a growth and help control bleeding. The chosen setting depends on the tissue, body site, and intended result.

The device does not diagnose a skin growth by itself. If a lesion needs laboratory examination, the clinician will explain whether tissue should be sampled or removed and sent for assessment. The unit is used only by a trained professional with suitable protective and infection-control measures.

Share your medical history, including an implanted electronic device, bleeding tendency, medicines that affect clotting, allergy history, and previous problems with wound healing. Ask how the area will be numbed, dressed, and protected afterward.

Keep the site dry or covered exactly as instructed, avoid picking a scab, and use the recommended wound-care product. Limit sun exposure while new skin forms. The appearance of the site can change during healing, so keep any planned follow-up appointment.

Contact the clinic for persistent bleeding, worsening pain, increasing redness, warmth, swelling, pus, or a bad smell from the wound. Seek urgent care for rapidly spreading swelling, fainting, breathing difficulty, or a severe reaction to a medicine or antiseptic.
