Electrosurgery

Overview

Electrosurgery is a minor procedure that uses a controlled, high-frequency electric current to remove small amounts of tissue or seal tiny blood vessels. It is not an electric shock — the current only affects the tip of a fine probe. It is often done in a GP surgery or clinic to treat small skin growths, warts, skin tags, or bleeding spots.

Electrosurgery is common in general practice and minor surgery clinics. It is a routine way to remove small skin problems or seal small bleeding blood vessels.

It can be used for adults and children when suitable. Older adults may have it for sun-damaged or bleeding skin spots. Your clinician will check whether it is right for you.

Symptoms

Common symptoms

• A small skin growth, tag, wart, or rough patch that your clinician wants to remove.
• A spot that bleeds, catches on clothes, or feels sore.
• A small blood vessel on the skin that bleeds after minor injury.
• A minor procedure where bleeding needs to be sealed.
• A skin change your clinician has checked and thinks is suitable for removal.

Symptoms in children

• Stubborn warts or skin tags that have not settled with other options.
• A skin lump your clinician wants to remove.
• Children may need extra reassurance and a parent or guardian present.
• The clinician will use child-friendly explanations and keep the area numb.

Symptoms in older adults

• Skin growths, sun-damaged patches, or bleeding spots that need treatment.
• Extra care may be needed if you take blood-thinning medicines or have an implanted heart device.
• Healing can be slower, so wound care and follow-up matter.
• Ask about support at home if the treated area is hard to care for.

Causes

Main causes

• Electrosurgery is not a disease, so it has no cause. It is a technique used to treat small tissue problems or to stop bleeding.
• It may be used for skin growths, warts, skin tags, small cysts, or bleeding spots after a clinician has checked them.
• It may also be used during minor procedures to remove tissue or seal blood vessels.

Risk factors

• Bleeding problems or taking blood-thinning medicines.
• An implanted heart device, such as a pacemaker or defibrillator.
• Pregnancy — tell your clinician so extra precautions can be taken.
• Diabetes, poor circulation, or a weakened immune system, which can slow healing.
• A history of keloid scars or poor scarring.
• A skin infection near the area to be treated.
• Smoking, which can slow healing.
• Allergy to numbing medicine or adhesive dressings.

When to see a doctor

See a doctor urgently if:

• Signs of infection: fever, spreading redness, warmth, pus, or bad smell.
• Bleeding that does not stop with pressure or keeps coming back.
• Severe pain, large swelling, or a wound that opens.
• A skin spot that is growing, bleeding, or changing quickly.
• Feeling unwell, dizzy, or faint after the procedure.

Book a routine appointment if:

• Before treatment: ask about benefits, risks, scarring, and alternatives.
• After treatment: if healing is slower than expected, or the scar bothers you.
• If the original problem comes back.
• If you have a new or changing skin spot.
• If you feel anxious about the procedure and want to talk it through.

Diagnosis

There is no special test to decide on electrosurgery. A clinician will ask about your health and medicines, look at the area, and explain whether electrosurgery is suitable. They will discuss other options and what to expect.

Tests that may be done

• A physical examination of the area.
• Your medical history and a review of your medicines.
• Sometimes a dermatoscope (a lighted magnifier) to look closely at the skin.
• Sometimes a biopsy (a small tissue sample) to check the cells.

What to expect at your appointment

You will usually have a short appointment. The clinician will explain the procedure, ask for your consent, and numb the area with numbing medicine. The electrosurgery itself often takes only a few minutes. You will be given aftercare advice before you go home.

Treatment

Your clinician will explain how electrosurgery works, what it can and cannot do, and the alternatives. The aim is to treat the problem with as little damage to nearby skin as possible. You will be asked to give consent before it starts.

Self-care at home

• Keep the area clean and dry as instructed.
• Do not pick the scab.
• Wash your hands before touching the area.
• Use sun protection on healed skin.
• Take pain relief only as advised by your clinician or pharmacist.
• Avoid swimming, saunas, or gym visits until healed if advised.

Medical treatments

Electrosurgery is done by a trained clinician using a fine probe. A numbing medicine is often used first. The probe uses high-frequency electric current to remove tissue or seal small blood vessels. You may feel warmth or a brief sting. The clinician controls the depth and area. Alternatives depend on the problem and may include no treatment with monitoring, prescribed skin treatments, freezing, or another minor procedure. Your clinician will discuss the benefits and risks with you.

When is surgery considered?

Electrosurgery may be suggested when a small skin growth, wart, skin tag, or area of bleeding needs treatment and other options are not suitable. It is usually a short, minor procedure in a clinic or GP surgery.

Living with this condition

Most people go home the same day and can return to normal activities as comfort allows. The treated area may look red, scab, or feel tender for a few days. Healing often takes one to three weeks, but this varies by site and size. Follow your aftercare advice.

Lifestyle tips

• Keep the area out of strong sun until healed.
• Avoid scratching or picking the area.
• Wear loose clothing over the area if needed.
• Avoid heavy exercise or swimming until your clinician says it is safe.
• Do not use creams or ointments that your clinician has not advised.

Diet and exercise

You can usually eat and drink normally. Gentle activity is fine. If the treated area is large or in a sensitive spot, your clinician may ask you to avoid strenuous exercise, swimming, or heavy lifting for a short time.

Mental health and emotional wellbeing

It is normal to feel nervous before a minor procedure or worried about scarring. Most people find it helps to ask questions and bring someone for support if allowed. If you feel very anxious, low, or have thoughts of harming yourself, contact your local emergency number or a crisis support service right away.

Prevention

Electrosurgery is a procedure, not an illness, so it cannot be prevented. You can lower the chance of problems by sharing your full medical history, including implanted devices, bleeding problems, pregnancy, and all medicines, and by following your aftercare instructions.

Vaccines

Not applicable. Vaccines do not prevent electrosurgery or its after-effects.

Screening programmes

Not applicable. There is no screening test for electrosurgery. If you have a skin spot that is new, changing, bleeding, or not healing, ask your clinician to check it.

Complications

If left untreated

• If the original problem is not treated, it may stay the same, grow, bleed, or become sore. Your clinician can explain the risks of waiting.
• Possible problems from electrosurgery include bleeding, infection, scarring, and a change in skin colour. Most are minor and can be treated.
• Rarely, damage to nearby tissue or a burn can happen. Trained clinicians take steps to reduce this.
• If you have an implanted heart device, the clinician will take precautions; without these, there may be a small risk of device interference.

Long-term outlook

Most people heal well after electrosurgery. The treated area often heals within one to three weeks, though it can take longer. A small scar or a change in skin colour is common and often fades. Your clinician will tell you when to follow up and what to watch for.
