What is electrocautery?

Electrocauterization is a procedure that uses an electric current to remove damaged or infected tissue, or to manage bleeding in tiny blood vessels. Moles, milia, warts, skin tags, angiomas, broken blood vessels (telangiectasia) and sebaceous hyperplasia (enlarged oil glands) can detract from the skin’s smooth surface and clear complexion.

If there is any question as to the status of a mole, you will be referred to your family doctor or dermatologist for assessment.

What to expect

  1. Consultation

    The Nurse Practitioner assesses the lesion. If there is any question as to the status of a mole, you are referred to your family doctor or dermatologist.

  2. Anaesthetic

    A local anaesthetic is applied topically or injected to minimize discomfort.

  3. Treatment

    An electric current removes the tissue. Some bleeding may occur from the anaesthetic injection and occasionally from the cautery itself, and is addressed at the time.

  4. Healing

    Crusting over the treated area falls off naturally over 3 to 7 days. Swelling, blistering, scabbing or flaking may take 1 to 3 weeks to heal, and the surface may be pink or sensitive to the sun for a further 2 to 6 weeks or longer.

FAQ

Will it hurt?

Some discomfort may be experienced during treatment. A local anaesthetic is applied topically or injected to minimize pain.

How long does it take to heal?

Crusting falls off naturally over 3 to 7 days. Swelling, blistering, scabbing or flaking may take 1 to 3 weeks to heal, and the surface may stay pink or sun-sensitive for another 2 to 6 weeks or longer.

Will it scar?

Scarring is a possibility whenever a treatment disrupts the skin’s surface. Following the post-treatment instructions carefully, and not picking the scab, minimizes the chance.

Can any mole be removed?

If there is any question as to the status of a mole, you will be referred to your family doctor or dermatologist for assessment first.
