In short
- Mole mapping photographs and closely images your skin and moles to create a baseline for comparing change over time.
- It is a monitoring tool, most useful for higher-risk people; its value depends on returning for comparison images.
- It does not remove or treat anything and does not by itself diagnose skin cancer; a suspicious lesion still needs a biopsy.
- It is not a guarantee: keep checking your own skin and report new or changing lesions promptly between visits.

What is dermoscopy mole mapping?
Mole mapping uses photography and close-up imaging to record your skin and moles in detail so they can be compared over time. It combines total body photography (overview photographs of the skin) with dermoscopy — looking at individual moles through a dermatoscope, a magnifier that makes them appear up to about ten times bigger — and often digital images of specific moles.
The point is to create a baseline. At future visits the new images are compared with the old ones, so that new moles, or changes in existing ones, can be spotted earlier than by memory or the naked eye alone. This is especially useful for people with many moles, atypical moles, or a personal or family history of melanoma, for whom tracking change is otherwise very hard.
Mole mapping does not remove or treat anything, and it does not by itself diagnose skin cancer. It is a monitoring tool. Its value largely depends on coming back for comparison images and on the skill of the person interpreting them.
Like any skin imaging, it is not a guarantee. It improves the ability to detect change but cannot find every cancer or predict the future, so knowing your own skin and reporting new or changing lesions remains essential between appointments.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Mole check vs mole mapping
| Mole check | Mole mapping | |
|---|---|---|
| What it is | One-off examination | Imaging stored for comparison |
| Best at | Assessing skin now | Detecting change over time |
| Needs repeat visits | Not necessarily | Yes, to compare images |
| Most useful for | Most people with a concern | Many or atypical moles, higher risk |
| Diagnoses cancer? | No, leads to biopsy | No, leads to biopsy |
The two often go together. Mapping adds value mainly for people who need their moles tracked over time.
Preparing for your test
- Remove make-up, fake tan and nail polish, as these can hide or distort moles in the images.
- Avoid heavy moisturiser or oil on the skin on the day unless told otherwise.
- Be ready to undress to your underwear for whole-body photographs, and ask for a chaperone if you would like one.
- Tie up long hair and mention moles in hidden areas such as the scalp or between the toes.
- Tell the clinician about any personal or family history of melanoma and your sun-exposure history.
- Bring any previous mole-mapping images or biopsy results to allow comparison.
- Ask how your photographs will be stored, who can see them, and how long they are kept.
What happens
The clinician or photographer asks about your skin and your risk, then takes a series of overview photographs of your skin, usually with you in your underwear and in set positions. A chaperone can be present if you wish. Long hair is moved aside and easily missed areas are included.
Selected moles are then examined and photographed close-up through a dermatoscope, with a little gel or oil on the skin; this does not hurt. The images are stored digitally and labelled so they can be found and compared at future visits.
A dermatologist or trained clinician reviews the images, sometimes on the day and sometimes afterwards, and advises which moles look harmless, which should be monitored, and whether any need removing and testing. At follow-up visits, new images are compared with the baseline to look for change. Mapping itself does not remove or treat anything.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Mole mapping is the wrong first step for a lesion that is clearly changing or bleeding now, which needs urgent assessment and likely biopsy rather than monitoring.
- Baseline imaging has limited value for someone who will not, or cannot, return for comparison visits.
- It is not a substitute for specialist examination if interpreted by poorly trained staff.
- It does not suit someone who needs treatment of a known skin cancer, which requires removal, not imaging.
Delay or rearrange if…
- You have fake tan, heavy make-up or nail polish on that would distort the images.
- You have a lesion that is changing now, which should be assessed urgently rather than mapped and watched.
- You are acutely unwell, when other care comes first.
- Previous images or biopsy results that would aid comparison are not available.
Alternatives to discuss
- A standard mole check or dermatology consultation without stored imaging.
- Knowing your own skin and using the ABCDE guide, with prompt review of any concern.
- A GP assessment and urgent referral for a suspicious lesion.
- The NHS pathway, which reserves this imaging mainly for higher-risk patients.
- No imaging for genuinely low-risk people, relying on self-checks and prompt review.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Creates a detailed baseline so new or changing moles can be spotted earlier
- Helps track many moles that would be impossible to remember accurately
- Can reduce unnecessary removal of stable moles by showing they are unchanged
- Supports earlier detection of melanoma in higher-risk people when used over time
- Gives you and your clinician a shared record to compare at each visit
Risks & complications
- False reassurance: imaging cannot guarantee no skin cancer will develop
- Only being fully useful if you return for comparison images
- Finding spots that prompt monitoring or a biopsy 'just in case'
- Anxiety while waiting for the result of any lesion that is removed
- A suspicious change being found that needs urgent referral and treatment
- A removed lesion turning out to be harmless in hindsight
- A small wound or tiny scar from any biopsy taken alongside mapping
- Concerns about how and where your skin photographs are stored and who can access them
- A skin cancer being missed, especially a fast-growing or unusual one, despite mapping
- An important lesion in a hidden area being overlooked
- A reaction to local anaesthetic if a biopsy is taken
Mole mapping improves the detection of change but is not a guarantee and does not diagnose cancer by itself. Its biggest practical limitation is that it depends on follow-up: a single baseline has limited value without comparison images, and fast-growing melanomas can still appear between visits. It also creates sensitive images of your body, so ask how they are stored and protected. Keep checking your own skin and report changes promptly rather than waiting for the next scan.
Published figures to discuss
Mole mapping is a low-risk, non-invasive process, so procedural complication rates are not the main issue. The relevant uncertainty is about accuracy and benefit: dermoscopy improves detection over the naked eye, and combining it with photography can help find early melanomas in higher-risk people, but firm sensitivity and specificity figures for whole programmes are limited and depend on follow-up and interpreter skill.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Accuracy of dermoscopy for melanoma (in trained hands) | Reported sensitivity around 89% and specificity around 84% in studies | Reflects dermoscopy of lesions, not whole programmes; depends on examiner training and does not capture lesions appearing later. | Total-body photography and sequential digital dermatoscopy for monitoring higher-risk patients (PMC)pmc.ncbi.nlm.nih.govPublished figure |
| False reassurance from mapping | Recognised | Mole mapping is a surveillance tool, not a guarantee. New or changing lesions between appointments still need review. | Guide sourcesClinical context |
| Unnecessary biopsy or removal | Recognised trade-off | More sensitive monitoring can lead to removal of benign lesions. This may be worthwhile in high-risk patients but should be explained. | Total-body photography and sequential digital dermatoscopy for monitoring higher-risk patients (PMC)pmc.ncbi.nlm.nih.govSource-linked context |
| Poor image comparability | Common practical limitation | Different lighting, angles, cameras or missing baseline images can make change harder to judge. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from mole mapping. 'Afterwards' means acting on the advice given, keeping an eye on any monitored moles, returning for comparison images, and waiting for the result of anything removed.
- Leaving with a baseline and advice rather than treatment
- Some moles labelled 'monitor and compare next time' rather than removed
- A small healing wound if a biopsy was taken
- Waiting a couple of weeks for any laboratory result
- Being asked to return for comparison images at a set interval
Aftercare
- Follow the advice for each mole, including which to monitor and what changes to report.
- Care for any biopsy site as instructed, keeping it clean and dry.
- Keep checking your own skin between visits, using a mirror or a partner for hidden areas.
- Use high-factor sun protection and avoid sunburn and sunbeds.
- Attend follow-up visits so new images can be compared with your baseline.
- Report promptly any new, changing, bleeding or odd-looking lesion, even before your next visit.
- Keep a note of where your images are held and how to access them.
- Notes on which moles are being monitored and what to look for
- A reminder set for your next comparison visit
- A mirror or a partner to help check hidden areas
- High-factor sunscreen and a sun-protection plan
- A note of how and when any results will be given
- Details of how your images are stored and how to access them
⚠ Get urgent help if…
- A new mole or spot, or one that is changing in size, shape or colour
- A mole that is asymmetrical, has irregular borders, more than one colour, or is larger than about 6mm (the ABCDE warning signs)
- A spot that itches, bleeds, crusts or will not heal over several weeks
- A scab or sore that keeps coming back in the same place
- A dark streak appearing under a nail without an injury
- Any mole you were asked to monitor that is now changing
- A biopsy site becoming increasingly red, swollen, hot or discharging (possible infection)
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good result from mole mapping is a clear baseline and, over time, the confident detection of change — picking up a new or evolving mole earlier than would otherwise be possible, while leaving stable moles alone. For higher-risk people, this can support earlier diagnosis of melanoma.
Mapping cannot prove that you will never develop skin cancer and does not diagnose cancer by itself; a suspicious lesion still has to be removed and examined in the laboratory. The result therefore always comes with advice to keep checking your own skin and to report changes promptly between visits.
A baseline set of images stays useful as a comparison for future visits, but its value grows only if you return for repeat imaging. How often that should happen depends on your risk — some higher-risk people are advised to attend every few months to a year. Because skin changes over time, mapping is an ongoing process rather than a one-off, and any previous reassuring comparison should not stop you acting on a new or changing lesion.
Related tests, treatments or support
Mole mapping is usually combined with a dermatology consultation and a full skin examination, and it leads into biopsy and treatment if a suspicious lesion is found. It is the more structured, image-based end of monitoring, building on a standard mole check.
Follow-up & long-term care
Follow-up is central to mole mapping: repeat imaging at intervals based on your risk allows new images to be compared with the baseline. You should also be told how any biopsy results are given, who reviews your images, and what changes should prompt an earlier visit.
- Attend repeat imaging at the interval advised so changes can be compared.
- Check your own skin between visits, using a mirror or a partner for hidden areas.
- Use high-factor sun protection and avoid sunburn and sunbeds.
- Report any new or changing lesion promptly rather than waiting for the next scan.
- Keep track of where your images are held and how to access them.
Repeat, follow-on and what comes next
- Moles labelled stable can change later and need reassessing at follow-up.
- Monitored moles may be removed at a future visit if comparison shows change.
- Repeat imaging is the norm, not a one-off.
- A reassuring comparison does not remove the need to act on new lesions.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear account of each mole and a plan for comparison at the next visit.
- Safety-netting advice on what changes should prompt an earlier review.
- Transparent information on image storage, access and data protection.
- A defined process and timeline for any biopsy results.
- A sensible, risk-based follow-up schedule rather than routine upselling.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether the service is baseline imaging only or includes repeat comparison visits
- The type of imaging used (standard photography, digital dermoscopy, or 3D systems)
- How many moles are imaged in detail
- Who interprets the images (dermatologist versus other) and their training
- Any biopsy taken and its laboratory (histopathology) analysis
- Image storage, reports and any insurance paperwork
- The fee and whether it covers baseline imaging only or follow-up comparisons too
- What imaging is included and how many moles are mapped in detail
- Who reviews the images and their training in dermoscopy
- The cost of any biopsy and its laboratory analysis
- How and where images are stored, and any charge to access them
- How results are given and what happens if a suspicious change is found
On the NHS? Mole-mapping-style imaging is mainly used on the NHS for higher-risk patients; many people access it privately for monitoring, though its value depends on follow-up and on who interprets the images.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Being given a reassuring comparison without being told it cannot guarantee the future.
- No clear plan or cost for the follow-up visits that give mapping its value.
- Unclear arrangements for how images are stored, protected and accessed.
- Removing moles, or not removing changing ones, without clear explanation.
- Marketing that overstates how much protection a baseline scan provides.
Marketing red flags
- Claims that mole mapping 'catches all melanomas' or guarantees safety
- Selling a one-off baseline scan as complete protection without follow-up
- Imaging interpreted by non-specialists presented as expert review
- Pressure to buy expensive packages regardless of your actual risk
- Vague answers about how your body images are stored and who sees them
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
