Mole removal: excision, testing, and the scar
Three things decide how this goes, and only one of them happens in theatre.

A mole is removed whole under local anaesthetic, usually in twenty to forty-five minutes, and closed with sutures. Every specimen at this clinic goes to histopathology whether or not the lesion looked suspicious. The wound heals in about two weeks; the scar matures over twelve to eighteen months, and most of its final quality is decided in the first six weeks.
Excision, not burning or shaving
There are quicker ways to make a mole disappear from the surface. Laser and cautery destroy the tissue, which means there is nothing left to send to a laboratory. If the lesion turns out to have been something other than a benign mole, that information is gone permanently, and so are the margins.
Full-thickness excision removes the lesion whole with a margin of normal skin around it, and produces a specimen that can be examined. That is why it is the default here for anything pigmented.
Why every specimen is tested
Most come back entirely benign, and that report is worth having in your file. The few that do not are the entire reason the rule exists. By the time a lesion is obvious enough to justify testing selectively, the months that mattered have already gone.
Ask any clinic whether the specimen will be sent, and ask when you will hear the result. At this clinic the report comes back in seven to ten working days and you are contacted either way — there is no such thing as no news being good news.
What decides the scar
The surgery sets the ceiling. The six weeks afterwards decide how close you get to it.
- •Placement. An excision oriented along a natural skin tension line heals finer than one across it.
- •Closure. Layered, so deep sutures carry the tension and the surface heals without stretching.
- •Tension for six weeks. Every unnecessary stretch across the line widens the final scar. This is the commonest reason a good excision produces a wide scar.
- •Silicone, daily, for three to six months. The only topical with consistent evidence behind it.
- •SPF 50, daily, for six months. Ultraviolet light on an immature scar causes pigmentation that is frequently permanent.
The timeline
| When | What happens |
|---|---|
| Day 0–2 | Pressure dressing stays on. Elevate where possible. |
| Day 5–7 | Sutures out — face. |
| Day 10–14 | Sutures out — trunk and limbs. |
| Day 7–10 | Histopathology report discussed with you. |
| Week 4–6 | The scar looks its worst. Red, firm, slightly raised. |
| Month 6–18 | Fades, flattens, softens to its final appearance. |
