What does a dermatologist diagnose and treat?
Start Here: What Does a Dermatologist Do?
A dermatologist is a medical doctor whose specialty is the skin, hair, and nails. Dermatologists care for far more than skin cancer. They diagnose rashes, acne, infections, hair loss, nail disorders, autoimmune disease, medication reactions, benign growths, precancers, and cancers.
During a skin-cancer evaluation, the dermatologist's job is not simply to glance at a mole and name it. The real job is to sort spots into useful action categories:
- clearly benign and safe to leave alone;
- benign but irritated or worth treating;
- worth photographing and watching in a defined way;
- suspicious enough to biopsy; or
- urgent enough to coordinate more quickly.
That distinction matters because harmless lesions can look alarming, while skin cancers can look ordinary. Seborrheic keratoses, angiomas, scars, inflamed follicles, dermatofibromas, and eczema can imitate cancer. Melanoma, basal cell carcinoma, and squamous cell carcinoma can imitate benign lesions.2,9–11
The purpose of the visit is not to biopsy everything. It is to make a better decision about what deserves reassurance, observation, treatment, or tissue diagnosis.
What is a professional skin check?
What Is a Skin Check?
A skin check is a professional examination of some or all of the skin. The scope depends on the reason for the visit.
| Type of visit | The question being answered | Typical focus |
|---|---|---|
| Focused diagnostic visit | “Does this particular spot need attention?” | The lesion, its history, surrounding skin, touch, dermoscopy, and whether biopsy is needed |
| Risk-based surveillance visit | “Because of my history, are any new or recurrent cancers developing?” | A deliberate examination plan based on prior cancer, immune status, mole pattern, treatment history, and hard-to-see sites |
| Routine screening discussion | “Would a planned skin examination add value even though I have no symptoms and no prior cancer?” | Baseline risk, potential benefit, uncertainty in population-screening evidence, and a reasonable interval if examination is chosen |
These are not interchangeable questions. A national statement about routine screening in asymptomatic people does not tell a person with a changing lesion to stay home. It also does not cancel surveillance after melanoma, repeated squamous cell carcinomas, or another high-risk history.1,3,4
Is this a changing spot, a surveillance visit, or routine screening?
First Decide Which Question You Are Asking
1. Do you have a new or changing spot?
This is the most straightforward reason to arrange an examination. New growth, evolution, recurrent bleeding, poor healing, pain, tenderness, a spot that looks unlike the others, or a lesion that simply worries you can justify a focused visit.
You do not need to prove that the lesion is cancer before making the appointment. That is the purpose of the evaluation.
2. Are you at higher risk even without one specific spot?
Some people have a higher probability of developing additional skin cancers or a greater need for professional comparison over time. A planned surveillance schedule can be useful when the expected value of looking is higher.
3. Are you an average-risk adult asking about routine screening?
The 2023 U.S. Preventive Services Task Force concluded that evidence was insufficient to determine whether clinician visual screening of asymptomatic adolescents and adults reduces illness or death at the population level.1 “Insufficient evidence” does not mean that examinations are useless. It means research has not established one universal program with proven mortality benefit for everyone.
What this means for you
Do not turn a population-research question into a personal rule. If you have a concerning lesion, seek evaluation. If you have important risk factors, build a surveillance plan. If neither applies, discuss the likely benefit and burden rather than assuming that everyone requires the same annual ritual.
Who benefits most from a planned skin check?
Who Benefits Most From a Planned Skin Check?
A professional examination is more likely to be useful when one or more of the following applies:
- a personal history of melanoma, basal cell carcinoma, squamous cell carcinoma, or numerous precancers;
- many moles or an atypical-mole pattern;
- a strong family history of melanoma;
- organ transplant, chronic lymphocytic leukemia, another hematologic disorder, HIV, or chronic immune-modifying therapy;
- extensive lifetime sun exposure or repeated blistering sunburns;
- very fair skin, substantial freckling, or difficulty tanning;
- a history of radiation or other treatment that changes local risk;
- numerous new lesions that are difficult to track; or
- an inability to examine the scalp, back, ears, soles, or other hidden sites reliably.1,3,4
| Risk pattern | Why professional surveillance may help | Useful question to ask |
|---|---|---|
| Prior skin cancer | A previous cancer changes the probability of another lesion and creates a need to examine treatment sites | “What follow-up interval fits the cancer I had?” |
| Immune suppression | Some skin cancers occur more often and can behave more aggressively | “Should my interval or urgency differ because of my immune status?” |
| Many or atypical moles | Whole-body comparison and photography may make change easier to recognize | “Would baseline images or dermoscopic monitoring add value for me?” |
| Strong family history | Inherited risk and shared phenotype may justify a more deliberate plan | “Does my family history change when surveillance should begin?” |
| Hard-to-see skin | The scalp, back, ears, nails, palms, and soles are easy to miss | “Which areas should a partner or clinician help me monitor?” |
Risk factors raise the expected value of the examination. They do not mean cancer will be found, and they do not create one identical schedule for everyone.
How should skin-check timing change with personal risk?
A Risk-Based Schedule Makes More Sense Than One Rule
No randomized trial has established one ideal examination interval for every adult.1 A useful schedule reflects:
- what type and how many skin cancers you have had;
- whether previous tumors were low risk or high risk;
- how quickly new lesions appear;
- your immune status and medications;
- your mole pattern and family history;
- whether you can reliably inspect your own skin; and
- whether photography or dermoscopy is being used for a defined purpose.
A person with a recent melanoma requires a different plan from an average-risk person with no symptoms. A transplant recipient developing repeated squamous cell carcinomas requires a different plan from both. The calendar should follow the clinical problem, not the other way around.
What happens during a complete skin check?
What Happens During a Complete Skin Check?
The exact sequence varies, but a thoughtful examination can include:
- History. Which spots are new? Which have changed, bled, hurt, or failed to heal? What cancers, biopsies, medications, and family history matter?
- Pattern comparison. Does one lesion look different from the patient's usual moles or growths?
- Hidden-site examination. Depending on the visit, the scalp, ears, nails, palms, soles, back, and other difficult areas may be checked.
- Palpation. Touch can reveal firmness, tenderness, fixation, scale, or depth that a photograph cannot show.
- Dermoscopy. A handheld magnifier with polarized or nonpolarized light can reveal pigment and vascular structures below the surface.
- Regional examination when indicated. Certain higher-risk cancers call for examination of nearby lymph-node regions.
- A documented decision. Reassure, treat, photograph, monitor, biopsy, or coordinate further care.
Skin cancer occurs in every skin tone. The examination should not be limited to classic dark melanoma or to heavily sun-exposed skin. Palms, soles, nails, scalp, and mucosal-adjacent sites may matter, especially when a lesion is new or changing.3,4
What expertise does a dermatologist add?
What a Dermatologist Adds
Whole-pattern recognition
The dermatologist sees the concerning spot in context. A brown lesion may look ordinary alone but become important when it is the only one with that pattern. Conversely, a dramatic-looking growth may match several stable benign lesions elsewhere.
Dermoscopy
Dermoscopy is not simply a brighter magnifying glass. It allows a trained clinician to inspect structures beneath the visible surface. In a Cochrane analysis, trained dermoscopy increased estimated melanoma sensitivity from about 76% to 92% when specificity was fixed at 80%.13,14
What that study means
At the same false-alarm rate, trained dermoscopy identified more melanomas than unaided visual inspection. It does not make the examination perfect, and it does not replace biopsy when tissue is needed. Its value is the combination of better visual information and a clinician trained to decide what that information means.
A calibrated biopsy threshold
The most useful expertise is not merely finding more abnormalities. It is knowing when the consequence of missing cancer is greater than the burden of biopsy, and when a benign pattern is reliable enough to avoid an unnecessary procedure.
When do skin photographs help—and when do they add noise?
When Photography Helps—and When It Adds Noise
Total-body photography can help selected people with many moles, high melanoma risk, or difficulty remembering what has changed. It creates a baseline so that new, changed, and stable lesions can be compared.
Photography should have a purpose. A 2025 randomized clinical trial of three-dimensional total-body photography plus sequential dermoscopy in high-risk patients increased biopsies and excisions without establishing a mortality benefit.15
What that study means
More surveillance technology can find more changes, but more information does not automatically mean better outcomes. The right program identifies who is likely to benefit, uses consistent images, has an expert interpretation process, and states what change will trigger examination or biopsy.
A photo is most useful when it answers a defined question: Did this particular flat lesion change over a planned interval? Short-term sequential dermoscopy can be appropriate for a carefully selected mildly atypical flat lesion, but it is not the pathway for a nodular, painful, bleeding, or rapidly changing lesion.16
| Tool | Best use | Important limit |
|---|---|---|
| Personal photographs | Documenting a specific spot or visible change | Lighting, angle, and scale can make comparison unreliable |
| Total-body photography | Baseline comparison in selected high-risk patients | Can increase biopsies and is not proven to reduce mortality |
| Teledermatology | Improving access and deciding how urgently an in-person visit is needed | Cannot reproduce touch, whole-skin comparison, or every lymph-node examination17 |
| In-person examination | Integrating history, pattern, touch, dermoscopy, and biopsy planning | A definitive diagnosis may still require tissue |
What can—and can’t—a skin check tell you?
What a Skin Check Can—and Cannot—Tell You
| A skin check can | A skin check cannot |
|---|---|
| Identify spots that deserve reassurance, monitoring, treatment, or biopsy | Guarantee that every cancer is visible or detectable at one moment |
| Compare one lesion with the rest of your skin | Turn an uncertain lesion into a definitive tissue diagnosis without biopsy |
| Find lesions in areas you cannot see easily | Prove that future skin cancer will not develop |
| Use dermoscopy and touch to improve the decision | Make one screening interval correct for everyone |
| Create a risk-based follow-up plan | Replace your attention to meaningful change between visits |
This is why a “normal skin check” is useful but not magical. It is a high-quality snapshot and decision point, not a lifelong guarantee.
How should I prepare for a skin check?
How to Prepare for the Visit
- Write down which spots are new, changing, painful, bleeding, or different.
- Bring prior pathology reports and treatment records when they are relevant.
- Bring dated photographs if they show real change.
- Tell the clinician about transplant medicines, immune-modifying drugs, family history, and prior cancers.
- Remove nail polish if a nail change is part of the concern.
- Wear clothing that is easy to change if a broader examination is planned.
- Ask what interval fits your risk and what change should trigger an earlier visit.
The best visit is not a silent scan. Point out what you noticed. Patients know the timeline of their skin better than anyone else.
What should I watch for between skin-check visits?
What You Can Do Between Visits
Learn the broad pattern of your own skin. Use mirrors or a partner for the back and scalp. Notice evolution, ugly-duckling lesions, recurrent bleeding, rapid growth, and new symptoms.
Self-awareness can prompt earlier evaluation, but it has not been proven to reduce melanoma mortality and cannot exclude cancer.5,6 The goal is not to become your own dermatologist. The goal is to recognize when the pattern has changed enough to ask for help.
Two simple memory tools can help: ABCDE prompts attention to asymmetry, border irregularity, color variation, diameter, and evolution; the ugly-duckling rule asks whether one lesion looks different from the rest of your pattern.7,8 Neither tool clears a lesion. A small, pink, fairly symmetric, or otherwise nonclassic melanoma can still matter.
A raised, tender, painful, bleeding, or rapidly changing lesion should not be placed into a casual photography plan simply because it is difficult to classify at home. Pain is nonspecific, but it is one of the clinical features that can increase concern for invasive squamous cell carcinoma in the right setting.12
How do skin-check recommendations change in common situations?
Three Common Examples
“I have no symptoms, no prior cancer, and no major risk factors.”
This is a general screening discussion. There is no evidence-based rule that every person needs the same interval. Discuss your baseline risk, your ability to examine your skin, and what changes should prompt a focused visit.
“I had melanoma and have many atypical moles.”
This is risk-based surveillance. A planned dermatologist schedule, careful whole-skin comparison, and selected photography or dermoscopic monitoring may be useful.
“One spot started bleeding and is getting larger.”
This is not a routine-screening question. It is a diagnostic visit. The spot should be assessed on its own timeline rather than waiting for an arbitrary annual date.
What does the evidence say about skin checks?
Evidence by the Numbers
Evidence by the NumbersTraining changes what dermoscopy can reveal
Training changes what dermoscopy can reveal
About 76% to 92% sensitivity
- Population
- Lesion-selected melanoma studies, mostly specialist settings
- Outcome
- Estimated sensitivity rose when trained dermoscopy was added at a fixed 80% specificity
- Time horizon
- At the time of diagnostic evaluation
What it means: A trained dermatologist can combine the naked-eye examination with dermoscopy to find clues that are not visible in a phone photograph.
Limitations: This is diagnostic-accuracy evidence, not proof that routine screening lowers mortality in every asymptomatic adult.
Evidence by the NumbersMore imaging did not automatically mean better care
More imaging did not automatically mean better care
2025 randomized trial
- Population
- Adults at high melanoma risk assigned to usual care or three-dimensional total-body photography plus sequential dermoscopy
- Outcome
- The imaging strategy increased biopsies and excisions without establishing a mortality benefit
- Time horizon
- Two years
What it means: Photography is most useful when it answers a defined surveillance question in a selected high-risk patient, not when it simply generates more abnormalities to investigate.
Limitations: The study tested one technology-assisted surveillance program in a high-risk population; it does not show that all clinical photography is unhelpful.
What questions should I ask at a skin-check visit?
Questions Worth Asking at the Visit
- Is this a focused lesion visit, a surveillance visit, or a general screening examination?
- Which risk factors matter most in my case?
- What areas should be examined or photographed?
- What made you choose reassurance, monitoring, treatment, or biopsy?
- If we monitor a lesion, what interval and what change would trigger biopsy?
- What should I watch for between visits?
Frequently asked questions about skin checks
Frequently Asked Questions
Does the USPSTF recommend against skin checks?
No. It found insufficient evidence for routine clinician visual screening in asymptomatic people without prior premalignant or malignant lesions. Suspicious lesions and high-risk surveillance are different questions.1
How often should I be checked?
There is no universal interval. Prior cancers, immune status, mole pattern, family history, rate of new lesions, and ability to monitor your skin should determine the plan.
Do I need a full-body examination for one spot?
Not every visit requires the same scope. However, comparison with the rest of the skin can reveal an ugly duckling or another lesion that changes the interpretation of the original concern.
Can my primary-care clinician start the evaluation?
Yes. Primary-care clinicians can evaluate many common lesions and determine urgency. Dermatology adds specialized pattern recognition, dermoscopy, biopsy selection, and management of uncertainty when needed.
Does darker skin eliminate skin-cancer risk?
No. Skin cancer can occur in every skin tone. Certain melanomas occur on palms, soles, or nails and may not resemble the classic dark irregular mole.3,4
Will a skin check find every skin cancer?
No examination is perfect. A skin check improves assessment at that moment, but patients should still report meaningful change between visits.
Are body photographs better than a dermatologist examination?
They answer a different question. Photographs can document change; the dermatologist adds history, touch, whole-skin context, dermoscopy, and a biopsy decision.
Does every unusual mole need biopsy?
No. Dermatologists often recognize stable benign patterns or use defined monitoring. Biopsy is most useful when the concern and consequences of delay outweigh the burden of the procedure.
