Suspicious Mole Removal in London: Urgent Assessment & Biopsy

What Counts as Urgent

Not every mole someone is worried about needs same-week attention, and being clear about the difference prevents both unnecessary anxiety and dangerous patience.

The distinguishing feature in the top three rows is change. A lesion that has always been unusual is a much weaker signal than one that was ordinary and is not any more — the reasoning is set out in melanoma early detection and the ABCDE rule.

The Assessment

Examination is by a consultant plastic surgeon using dermoscopy rather than naked-eye inspection, because the features that separate melanoma from its common mimics — pigment network, vessel architecture, blue-white structures — sit beneath the surface and are not visible otherwise.

Three things are established before any decision is made:

• What the lesion is likely to be. A high proportion of lesions referred with concern turn out to be seborrhoeic keratoses, benign naevi or vascular lesions, each with a recognisable dermoscopic signature.
• Whether it feels as it looks. Firmness and fixation are not visible in any image. A firm lesion is treated differently from a soft one with identical appearance.
• How it sits against your other lesions. The comparison across a whole person is a distinct judgement from the examination of one spot.

Where the answer is that the lesion is benign and unchanged, that is the end of it, and removal becomes a choice rather than a recommendation. Where it is not, the assessment moves directly to how it comes out.

Why It Comes Out Whole

This is the single most consequential decision in the entire pathway, and it is made before the lesion is touched. For a suspected melanoma the standard here is an excision biopsy with a 2 mm margin and a cuff of fat — not a sample, and not a superficial removal.

The reason is Breslow thickness.

“Breslow is measured in millimetres from the granular layer of the epidermis to the deepest tumour cell, and it is the dominant determinant of prognosis, of the width of the definitive wide local excision, and of whether sentinel lymph node biopsy is offered. A shave that transects the base of the tumour destroys that measurement and the report can only say ‘at least X mm’, which risks under-staging the patient and under-treating them. The thresholds matter in practice: 0.8 mm or less without ulceration is managed differently from thicker or ulcerated lesions. A shave biopsy that loses the base can cost a patient a sentinel node biopsy they should have been offered.”— Mr Onur Gilleard, Consultant Plastic Surgeon

Two consequences follow, and both are absolute:

1. A shave is not acceptable for a pigmented lesion under suspicion. It removes the lesion and the measurement at the same time.
2. Destroyed tissue gives nothing at all. Laser, cautery or freezing leave nothing for a pathologist. If that lesion was a melanoma, the diagnosis and the staging are lost together.

The one exception is a lesion where complete excision would be impractical or disfiguring at the diagnostic stage — a large facial lentigo maligna, a very large truncal lesion, or an acral site. There a punch or incisional biopsy is taken from the most atypical or thickest area, accepting the known limitation that a negative punch does not exclude melanoma elsewhere in the same lesion. The general comparison of removal methods is in shave versus excision.

The Removal Itself

Excision of a mole is a short procedure under local anaesthetic. The area is cleaned and numbed; the only sharp sensation is the anaesthetic going in. The lesion is removed with a margin of normal skin around it, and the wound is closed with sutures, leaving a fine line rather than an open area.

Practical points patients ask about beforehand:

Scar placement

Where anatomy allows, the incision is oriented along natural skin tension lines so the resulting line falls where it is least conspicuous. This is a plastic surgical consideration rather than an incidental one, and it is a substantive argument for who performs the excision.

Sutures

Removed at five to seven days on the face and ten to fourteen days on the trunk, back and limbs. You are given the interval at the time rather than left to guess.

Aftercare, in order

The dressing stays dry and intact for five days; after that, shower normally and pat dry. No soaking, baths, swimming or sauna until the sutures are out and the wound is sealed. Expect the scar to be red, firm and slightly raised for six to twelve weeks, with remodelling continuing for twelve to eighteen months. Silicone gel or tape from two to three weeks once the wound is fully closed, daily for at least three months. SPF 50 over the scar for twelve months — new scars pigment permanently if they are burnt. Contact the clinic for spreading redness, increasing pain after day three, discharge, or fever.

Activity — the part that decides the scar

Back, shoulder and chest wounds sit under the most tension and spread the most. Avoiding gym, lifting and stretching for two weeks is, in the surgeon’s assessment, the single biggest determinant of the final scar — more than technique, more than dressings.

The Result, and How You Get It

The removed tissue is examined by a pathologist. Histology takes three to seven days. How the result reaches you depends on what it says, deliberately:

• Benign — the commonest outcome by a wide margin — is sent by email.
• Pre-malignant or malignant results are telephoned first, before any written report is sent. Nobody learns that they have a melanoma from an email attachment.

Where melanoma is confirmed, the pathway is not discretionary:

“Every melanoma is referred into a skin cancer MDT — this is a national requirement, not a local preference, and no private clinic manages melanoma outside one.”— Mr Onur Gilleard

In practice that means a formal referral to the nearest hospital with a skin cancer multidisciplinary team, the GP informed, and the histology released so the receiving trust’s own pathologists can review the specimen themselves. The excision that established the diagnosis is the first part of treatment rather than something separate from it.

Histological analysis is charged at £180 and is applied where the lesion’s features warrant it rather than routinely on every removal.

Private or NHS?

Both routes exist and they suit different situations.

The NHS urgent suspected-cancer pathway is designed for exactly this and moves quickly once a GP has made the referral. If a lesion genuinely looks like a melanoma, that route is appropriate and is not improved upon by paying.

Private assessment is useful where you want to be seen without first securing a GP appointment, where a GP has been unconcerned but you are not, or where the lesion is more likely benign but you want it dealt with rather than watched. It also allows assessment and removal in a single visit.

The two are not mutually exclusive: a private diagnosis can be brought to a GP, and where something serious is confirmed the NHS pathway is available. The criteria and waits are set out in removal on the NHS.

Cost

The clinic operates a see-and-treat service for the majority of conditions, so assessment and removal generally happen in one visit. Appointments at 101 Harley Street: mole removal or contact the clinic. Where the concern is broader than a single lesion, clinical mole surveillance may be the more useful starting point.

Frequently Asked Questions

How quickly can a suspicious mole be seen?

Assessment and, where appropriate, removal usually take place in a single visit under the see-and-treat model. A lesion that is growing rapidly, bleeding without injury or ulcerating should be seen within days rather than weeks.

Can it be removed on the same day?

Yes. Where a lesion needs removing, the excision is carried out at the same appointment. The examination comes first because it determines whether the lesion should be removed at all and, if so, by which method.

Why remove the whole mole rather than take a sample?

Because melanoma is staged by Breslow thickness, measured from the granular layer to the deepest tumour cell, and a shave that transects the base destroys that measurement — the report can then only say “at least X mm”. Since the 0.8 mm threshold determines whether a sentinel lymph node biopsy is offered, an under-staged lesion can cost a patient a procedure they should have had. The standard is a 2 mm margin excision biopsy with a cuff of fat.

Can a suspicious mole be lasered or frozen off?

Not if there is any suspicion. Those techniques destroy the tissue, leaving nothing for a pathologist to examine. They are appropriate for lesions already confirmed as benign, not for lesions where the diagnosis is the question.

Will it leave a scar?

An excision leaves a fine line rather than a flat mark. Sutures come out at five to seven days on the face and ten to fourteen days elsewhere. The largest single influence on the final result is avoiding tension on the wound — no gym, lifting or stretching for two weeks, particularly for back, shoulder and chest sites — followed by silicone gel from two to three weeks and SPF 50 over the scar for twelve months.

How are results given?

Histology takes three to seven days. A benign result is emailed. A pre-malignant or malignant result is telephoned before any written report is sent, and where melanoma is confirmed the case is referred into a skin cancer multidisciplinary team — a national requirement rather than a local choice.

What if it turns out to be benign?

That is the commonest outcome by a wide margin, and it is what the examination is designed to establish rather than assume. A benign result closes the question definitively, which watching never quite does.

Should I go to my GP instead?

If a lesion genuinely looks like a melanoma, the NHS urgent suspected-cancer pathway is designed for it and moves quickly — that route is appropriate. Private assessment suits situations where you want to be seen without waiting, or where a lesion is more likely benign but you would rather have it dealt with than monitored.
