What is a mole, and what does excision mean?
A melanocytic naevus is a collection of pigment-producing cells in the skin. Moles may be flat or raised and light or dark. Skin tags, warts and other skin lesions are different conditions, even when they look similar.
Excision means cutting out a lesion. The wound is usually closed with stitches and the tissue is examined under a microscope. Removal and the resulting scar must be considered together.
Does every mole need removal?
Most moles are benign and need no treatment. An unchanged mole without suspicious features may be monitored. Removing every mole does not eliminate skin cancer risk; melanoma can arise in previously normal skin.
Suspicious change, recurrent irritation or bleeding, difficulty monitoring a lesion, or concern about appearance may lead to assessment for removal. For cosmetic removal, the acceptability of the replacement scar is important.
Which changes need prompt assessment?
An unusual new lesion, one that looks different from the others, continuing growth, spontaneous bleeding, a non-healing sore or changing symptoms should be examined. These findings do not by themselves diagnose cancer.
The ABCDE guide covers Asymmetry, Border irregularity, Colour variation, Diameter and Evolution. A lesion smaller than 6 mm can still be melanoma. Do not wait for every feature to develop; ABCDE is an awareness guide, not a self-diagnosis test.
What is assessed before removal?
The history includes when the lesion appeared, changes, bleeding, previous treatment and personal or family skin cancer history. Size, depth, location, surrounding skin and the likely wound are assessed. Previous photographs and pathology reports can help.
Dermatology assessment and dermoscopy by an experienced clinician may be appropriate. Dermoscopy helps inspect skin structures but does not replace tissue examination when indicated. A photograph alone cannot establish a definite benign or malignant diagnosis.
How is a mole excised?
The area is identified, cleaned and anaesthetised. The lesion is removed to a depth and margin appropriate for the diagnostic question. Bleeding is controlled and the wound is usually sutured, sometimes in more than one layer.
An elliptical removal can leave a line longer than the mole’s diameter. Larger or difficult defects may require a local flap or skin graft; these possibilities are discussed separately.
For suspected melanoma, complete full-thickness excision with a narrow surrounding margin is preferred where appropriate. Large or particular sites may need a different biopsy approach. A diagnostic biopsy margin is not the same as the wider treatment margin that may be required after a cancer diagnosis.
Why is the tissue sent for examination?
An excised naevus is sent for histopathology to identify the lesion and assess atypical or malignant features. A reassuring appearance does not replace microscopic examination. Margins can also be assessed when the specimen allows.
The report may support observation or indicate further removal or specialist assessment. Atypia does not automatically mean melanoma; its degree, margins and clinical findings matter.
Turnaround depends on the laboratory and any additional tests. No news does not mean a normal result. Agree how to obtain the report, contact the practice if it is delayed and keep a copy.
Are excision, shaving and laser the same?
Selected benign raised lesions may be suitable for a surgical shave. Sampling depth, scar pattern and the possibility of recurrent pigment differ from complete excision; no single method suits every mole.
Destructive laser, cautery or freezing may compromise histological assessment or leave insufficient tissue. Suspicious pigmented lesions require adequate diagnostic sampling. Monitoring is an option only when medically appropriate. Home cutting, burning and mole-removal products can cause scarring, infection and delayed diagnosis.
Anaesthesia, procedure time and discharge
Many small, suitably located lesions can be removed under local anaesthesia. The injection may sting; once numb, pressure or movement may still be felt. Tell the team if there is sharp pain.
Children, extensive procedures or particular circumstances may require a different anaesthetic or setting. Local anaesthesia also carries allergy, fainting and rare serious drug-reaction risks.
Duration depends on size, depth, number, site and closure. Small local procedures are generally outpatient treatments. Sedation or general anaesthesia requires a separate fasting, escort and monitoring plan.
Will mole removal leave a scar?
Surgical excision leaves a permanent scar. Careful planning and low-tension closure aim to make it less noticeable while preserving diagnostic requirements. A scar may be more noticeable than the original mole.
Scars can remain pink, firm, raised, widened, indented or differently coloured, and change over months. Keloid tendency, site, tension, skin characteristics, infection and sun exposure matter. Tell the surgeon about previous abnormal scarring.
On the eyelid, nose or lip, nearby function matters as well as appearance. Scar treatments are considered individually after the wound has closed.
How should you prepare?
Report all medicines and supplements, allergies, bleeding disorders, diabetes, immune suppression, implanted cardiac devices, pregnancy, nicotine use and previous anaesthetic problems.
Do not stop prescribed blood thinners or other medicines yourself. Any change requires a decision with the prescribing clinician and surgical team. Follow individual preparation instructions rather than a blanket medication or fasting rule. Plan stitch review, pathology follow-up, travel, driving and work arrangements.
Stitches, wound care and return to activities
Some tenderness, swelling, bruising or a small blood stain on the dressing can occur initially. Follow the closure-specific instructions for dressings and washing. Avoid rubbing, picking scabs or applying unapproved products.
Stitch removal depends on site, wound tension and healing; the same day does not apply to the face, trunk and limbs. Dissolving stitches do not remove the need for review.
Light activities may be possible the same day after a small local procedure. Heavy lifting, stretching the wound and sport may need longer restriction. Wait for wound closure and clearance before swimming. Protect healing skin from the sun and agree when sunscreen can be applied.
Risks and unwanted outcomes
Every medical intervention, procedure and operation carries risks. Depending on the treatment and individual health, these may include death, disability and temporary or permanent unwanted functional or aesthetic outcomes.
No medical intervention, procedure or operation guarantees the result or results a patient wishes to achieve.
Risk depends on the extent of treatment and individual health. A small local procedure and extensive surgery do not have identical risks; local anaesthesia does not make risk zero.
Bleeding, haematoma and infection
Bleeding, a collection of blood or infection may require dressings, medicines, drainage or another operation.
Wound separation and scarring
Wounds can reopen or heal slowly. Permanent raised, widened, depressed or differently coloured scars, including keloids, can occur.
Sensation and nearby structures
Numbness, hypersensitivity or persistent pain may occur. Depending on depth and site, nerves and adjacent structures may be injured, occasionally with permanent sensation or movement changes. Eyelid or lip distortion is a site-specific consideration.
Residual lesion and further surgery
Residual cells, recurrent pigment or a lump can occur. Pathology findings or an unacceptable scar may require further treatment.
Anaesthesia and allergy
Local anaesthetics, antiseptics, adhesives and other materials can cause reactions. Severe allergy or drug toxicity may need emergency care; sedation or general anaesthesia adds its own risks.
Persistent problems and additional treatment
Wound care, scar treatment, surgery or hospital care may be needed. These have their own risks and costs; complete correction cannot be guaranteed.
When should you seek urgent help?
Contact the team promptly for continuing bleeding, rapidly increasing swelling, worsening pain, spreading redness, fever, pus, wound opening or new weakness. For a minor ooze, follow the supplied instructions for uninterrupted pressure through clean gauze; obtain medical help if bleeding continues.
For heavy bleeding, fainting, breathing difficulty or swelling of the face, tongue or throat, call 112 or attend emergency care. Do not wait for a routine appointment.

Frequently asked questions
Must every mole be removed?
No. Many stable, non-suspicious moles can be monitored. Examination, change over time and the person’s concerns determine the plan.
Does removal cause cancer?
Appropriate biopsy or excision does not turn a mole into cancer. Examining suspicious tissue enables diagnosis and planning of any necessary treatment.
Which moles need prompt examination?
Growing, changing, unusual, spontaneously bleeding or non-healing lesions need assessment. None of these findings alone proves cancer.
Can a small mole be suspicious?
Yes. Melanoma can be smaller than 6 mm. Diameter alone cannot establish whether a lesion is safe.
Can a photograph establish the diagnosis?
It may provide preliminary information, but cannot replace examination, dermoscopy when appropriate or indicated histopathology.
Is the removed mole examined?
Excised naevus tissue is sent for histopathological examination. An apparently benign appearance does not replace microscopy.
Does a pathology request mean cancer?
No. Examination identifies the lesion and clarifies uncertainty. The result may be benign.
Is scar-free removal possible?
Surgical excision leaves a permanent scar. A fine scar may be achievable, but invisible healing or a better appearance than the mole cannot be promised.
Is laser the same as excision?
No. Destruction can compromise pathological assessment. Adequate diagnostic tissue takes priority in suspicious pigmented lesions.
Can local anaesthesia be used?
Often for small, appropriately located lesions. Age, extent and additional surgery can require a different plan.
Is it painful?
The injection may sting or burn briefly. Pressure and movement can remain after numbing; report sharp pain.
How many minutes does it take?
Size, depth, site, number and closure determine duration. One fixed time does not apply to everyone.
When are stitches removed?
Timing depends on site, tension and healing. Dissolving stitches have a different follow-up plan.
Can I return to daily life the same day?
Light work may be possible after a small local procedure. Wound location, care and job demands matter; sport needs separate clearance.
When can I shower?
Follow the specific dressing and closure instructions. Avoid prolonged soaking of a fresh wound; wait for healing before swimming.
Can the mole return?
Residual cells can produce pigment or a lump. This does not automatically mean cancer but requires review with the earlier pathology report.
When is the pathology result available?
The laboratory and additional tests determine this. Agree how to obtain the result and whom to contact if it is delayed.
What if the result is suspicious or malignant?
Further assessment, wider removal or specialist treatment may be required. Initial excision is not always the final treatment.
Can facial, eyelid or lip moles be removed?
Selected lesions can be removed. Nearby function and wound closure matter as well as scarring.
Should I continue monitoring other moles?
Yes. Removing one mole does not replace ongoing skin surveillance. Report new or changing lesions; review frequency depends on individual risk.
What affects the cost?
Size, number, site, depth, anaesthesia and closure affect cost. Clarify whether pathology, follow-up and possible additional procedures are included. Similar-looking lesions may require different surgery; an individual plan follows examination.
