Mole Removal Treatment

Moles (naevi) are pigmented benign growths in the skin. Most are entirely harmless and are removed only for cosmetic reasons; some, however, may be early signs of skin cancer. The first step is therefore always correct assessment — followed by safe, scar-conscious removal using the most appropriate method.

What Is a Mole and Why Does It Form?

Moles form when melanocytes (pigment-producing skin cells) cluster within the skin layers. Genetic predisposition, sun exposure and hormonal changes drive their formation. Most moles are not present at birth — they appear during the first two decades of life and stabilise in adulthood. Their colour can range from light brown to black; they may be flat, slightly raised or pedunculated.

Which Moles Should Be Removed?

There are two main reasons: medical (suspected atypia, rapid change, bleeding, itching) and cosmetic (annoyance, friction from clothing, razor cuts). Any removal decision is made after a dermatoscopic examination. The ABCDE rule guides risk assessment:

• Asymmetry — one half does not match the other
• Border — irregular, notched or blurred edge
• Colour — multiple shades (brown, black, red, blue)
• Diameter — greater than 6 mm
• Evolution — change in size, shape, colour or surface over recent months

Any mole meeting these criteria must be removed by full excision with histopathology, not surface-shaving. Electrocautery or laser shaving is strictly inappropriate when there is medical suspicion — no sample can be obtained and the diagnosis is missed.

Removal Methods

1. Radiofrequency (Electrocautery)

The preferred method for low-risk, small, superficial moles with no histological suspicion. High-frequency current removes tissue layer by layer with simultaneous coagulation, so bleeding is minimal. Used successfully on the face and other delicate areas. Performed under local anaesthesia in a few minutes; healing takes 7–14 days and leaves no visible scar when correctly performed.

2. Surgical Excision

The gold standard for atypical or deeper moles. The mole is removed in full thickness with a safety margin of healthy surrounding tissue and closed with sutures. The specimen is sent to histopathology. Its biggest advantage is definitive diagnosis. Incisions are planned along Langer's lines to minimise scarring; silicone gels and PRP can be used afterwards to optimise scar healing.

3. Laser (Only When No Atypia Is Suspected)

Q-switched or picosecond lasers can be used for very superficial, purely pigmented moles (typically "lentigines"). As this method does not allow a tissue specimen, it is unsuitable for any mole with clinical suspicion.

Procedure Flow

Every session starts with a thorough examination: each suspicious mole is photographed and dermatoscopically assessed. After the plan is agreed, local anaesthesia is applied (topical cream or injection), the chosen technique is performed, and a dressing is applied. The procedure takes 10–45 minutes in an office setting. For large numbers of moles, sessions are scheduled in groups of 6–8.

Aftercare

• Dressing is kept dry for 24–48 hours; gentle cleaning is then advised.
• A crust forms and falls off naturally in 5–10 days — do not pick at it.
• High SPF sun protection for at least 4 weeks reduces post-inflammatory hyperpigmentation.
• Silicone-based scar gels are recommended for 8–12 weeks.
• Follow-ups are scheduled at 2, 6 and 12 weeks.

Recurrence and New Moles

Fully excised moles rarely recur; some pigment may remain after superficial techniques. New moles develop throughout life — annual full-body dermatoscopy is the most powerful early detection tool for melanoma.
