Melanoma Screening: When and How to Get Checked

Key Takeaways

• There is no universal population-wide melanoma screening program, the USPSTF found insufficient evidence to recommend routine screening for average-risk adults, but this does not mean skin monitoring is unimportant.

• High-risk individuals (personal or family history of melanoma, many or atypical moles, fair skin with significant sun history, immunosuppression) are strongly advised to have regular professional skin exams.

• Monthly skin self-exams allow you to catch changes early, between professional appointments.

• A professional full-body skin check with a dermatologist typically takes 15–30 minutes and uses dermoscopy to evaluate suspicious lesions more accurately than the naked eye.

• Total body photography (mole mapping) can help detect changes in moles over time and is increasingly available, though not always covered by insurance.

• After a melanoma diagnosis, structured surveillance schedules, with your oncologist and dermatologist, are essential, as recurrence can happen years later.

Is There a Standard Melanoma Screening Program?

There is no universal screening recommendation for melanoma in average-risk adults in the United States. The USPSTF (U.S. Preventive Services Task Force) concluded in its 2023 update that evidence is insufficient to assess the balance of benefits and harms of screening for skin cancer, including melanoma, in asymptomatic adults without a history of skin cancer. This is not a statement that screening is harmful; it reflects that robust randomized trial evidence on population-wide mortality benefit does not yet exist.

What this does not mean: that skin monitoring is unimportant, or that high-risk individuals should forgo screening. Major dermatology and oncology organizations, including the American Academy of Dermatology, strongly advocate for regular skin checks in people with elevated risk factors. And the evidence that early-stage melanoma is far more curable than late-stage melanoma is unambiguous, the 5-year survival rate for localized melanoma approaches 99%, compared to approximately 35% for distant disease.

The practical implication for most people: know your skin, perform monthly self-exams, understand your personal risk factors, and make a professional skin exam a priority if you have any of the risk factors described below.

Who Should Get Regular Skin Exams?

While anyone can develop melanoma, certain groups have a meaningfully higher risk and should prioritize professional skin monitoring:

Personal history of melanoma. If you have had melanoma before, your risk of developing a second primary melanoma is significantly elevated. Lifelong surveillance with a dermatologist and oncologist is standard care.

Family history of melanoma. One first-degree relative with melanoma approximately doubles your risk. Two or more affected first-degree relatives, or a family pattern consistent with Familial Atypical Multiple Mole and Melanoma (FAMMM) syndrome, warrants intensive monitoring and possible genetic counseling.

50 or more common moles. A high total mole count is independently associated with elevated melanoma risk.

Atypical moles (dysplastic nevi). Having one or more atypical moles: moles that are asymmetrical, have irregular borders, or contain multiple colors, increases risk and warrants regular professional monitoring.

Fair skin, history of sunburns, or significant cumulative sun exposure. People who burn easily, have had multiple blistering sunburns (especially in childhood or adolescence), or have spent years in high-UV environments face elevated risk.

History of tanning bed use. First use before age 35 increases melanoma risk by approximately 75%. A history of tanning bed use is a meaningful risk factor that warrants professional monitoring.

Prior non-melanoma skin cancer. A personal history of basal cell or squamous cell carcinoma signals accumulated UV damage and correlates with elevated melanoma risk.

Immunosuppression. Organ transplant recipients and others on long-term immunosuppressive therapy have significantly increased skin cancer risk.

Giant congenital nevi. Large moles present at birth carry a meaningful lifetime risk of malignant transformation and require ongoing specialist monitoring.

If you are unsure whether you qualify as high-risk, bring the question to your primary care physician or a dermatologist. A brief review of your history can clarify what level of monitoring makes sense for you.

The Monthly Skin Self-Exam

Regular skin self-examination allows you to notice changes in moles and spots between professional appointments, and to bring those changes to your doctor’s attention promptly. Most melanoma is first noticed by the patient or a partner, not a physician, which underscores how important self-exam is.

What you need: A full-length mirror, a hand mirror for hard-to-see areas, a comb or hair dryer for the scalp, and good lighting.

Step-by-step guide:

1. Face, neck, and scalp. Examine your face, including the nose, lips, ears (front and back), and behind the ears. Part your hair in sections and use a comb or hair dryer to examine the scalp, or ask a partner to help. Don’t forget the back of the neck.

2. Chest and abdomen. Examine the front of your chest, stomach, and sides. Women should examine the skin under the breasts.

3. Arms and hands. Check the tops and undersides of your arms. Examine each hand front and back, between the fingers, and under the fingernails.

4. Back and buttocks. Use the hand mirror with the full-length mirror to examine your back, buttocks, and the back of your legs. Ask a partner to help if needed.

5. Legs and feet. Sit down and examine the front and back of your legs. Check the soles of your feet, between the toes, and under the toenails.

6. Genitals. Use a hand mirror to examine the genital area.

What to look for: Apply the ABCDE criteria, Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, Evolving. Also look for the “ugly duckling” sign: any spot that looks distinctly different from all your other moles or spots.

Photographing suspicious spots. Taking a photo of any new or changing spot creates a baseline for comparison at future self-exams. Use a consistent distance, angle, and lighting for meaningful comparison. Note the date.

When to call vs. when to watch. If a spot is actively changing, growing, shifting in color, developing new symptoms like itching or bleeding, call your dermatologist promptly rather than waiting. If you simply want a spot evaluated, schedule an appointment at your next available opportunity. There is no downside to having something checked.

Professional Skin Exams: What to Expect

A professional full-body skin exam is performed by a dermatologist (or sometimes a primary care physician or nurse practitioner trained in skin assessment). The appointment typically takes 15–30 minutes.

What happens. You will be asked to undress to your underwear and put on a gown. The provider will systematically examine your skin from head to toe, including the scalp, between the toes, the soles of the feet, and under the nails. A dermoscope is often used to magnify and assess suspicious lesions more closely. You will likely be asked about any spots you are concerned about, bring a list or show photos of anything you’ve noticed.

No biopsy on the day of the exam is typical unless a clearly suspicious lesion is found that warrants immediate removal. More often, the provider will note concerning spots for follow-up, discuss management, and recommend a return visit or biopsy at a separate appointment.

Frequency. For average-risk individuals with no history of skin cancer, an annual full-body skin exam is commonly recommended by the American Academy of Dermatology, though there is no formal population-wide guideline mandating it. For high-risk individuals, those with a history of melanoma, multiple or atypical moles, or strong family history, appointments every 3–6 months may be appropriate. Your dermatologist will recommend a schedule based on your individual risk profile.

Finding a dermatologist. If you do not have an established dermatologist, the AAD’s “Find a Dermatologist” tool (aad.org) is a reliable starting point. NCI-designated cancer centers often have specialized pigmented lesion clinics for patients with elevated risk.

Total Body Photography and Mole Mapping

Total body photography is a baseline documentation technique in which standardized photographs of the entire body surface are taken and stored. At follow-up appointments, current photographs can be compared against the baseline to detect new lesions or changes in existing ones that might not be apparent from memory alone.

Mole mapping using total body photography has been shown to help detect melanomas that would otherwise be missed at clinical examination, particularly in patients with many moles. Changes visible in photographs can trigger biopsy of lesions that would not otherwise have been prioritized.

The limitation is access: total body photography services are more available at academic medical centers and specialized pigmented lesion clinics than in general dermatology practices. They are not always covered by insurance. If you have a high mole count, a history of melanoma, or familial melanoma risk, ask your dermatologist whether total body photography is available and appropriate for you.

After a Melanoma Diagnosis: Surveillance Schedule

After treatment for melanoma, lifelong monitoring is essential. Melanoma can recur, both locally and at distant sites, sometimes years after the initial diagnosis. Structured surveillance allows early detection of recurrence, when treatment is most likely to be effective.

General surveillance schedule (varies by stage):

• Stage I–II: Dermatology visits every 6–12 months for the first 5 years, then annually. Monthly self-exams throughout.

• Stage III: Visits every 3–6 months for the first 2–3 years, then every 6 months through year 5, then annually. Imaging (CT or PET/CT) may be part of the protocol.

• Stage IV (after treatment): Every 3 months initially, with imaging at each visit or as clinically indicated. Schedule adjusted based on treatment response.

What surveillance involves. Each visit typically includes a thorough skin exam, lymph node palpation, and review of any new symptoms. Imaging (CT, PET/CT, MRI) is used more consistently in higher-stage surveillance protocols. Blood tests including LDH may be monitored.

Watch for. New or changing skin spots anywhere on the body, swollen or firm lymph nodes in the neck, armpit, or groin, persistent headaches or neurological symptoms, unexplained fatigue or weight loss, or any new symptoms that feel different from your baseline. Report any of these to your oncologist promptly rather than waiting for the next scheduled appointment.

Recurrence can happen years later. Melanoma has been known to recur 5, 10, or even 20 years after initial diagnosis. This is one reason why lifelong surveillance, rather than a fixed endpoint, is the standard. Regular monitoring is not a sign of pessimism; it is simply good practice.

Frequently Asked Questions

Should I get screened for melanoma?

If you have any of the risk factors described above, personal or family history of melanoma, many or atypical moles, fair skin with significant UV exposure history, use of tanning beds, immunosuppression, or a history of other skin cancers, yes, you should see a dermatologist regularly for professional skin exams. For average-risk adults, no government body currently mandates routine screening, but the USPSTF finding of “insufficient evidence” means the question is open, not that screening is discouraged. Monthly self-exams are appropriate for everyone.

How often should I see a dermatologist for skin checks?

This depends on your risk level. Most dermatologists recommend an annual full-body skin exam for average-risk adults. For individuals with elevated risk, multiple or atypical moles, personal or family history of melanoma, significant sun exposure history, or immunosuppression, every 3–6 months may be recommended. After a melanoma diagnosis, your oncologist and dermatologist will establish a specific surveillance schedule based on your stage.

What does a full-body skin exam involve?

You will undress to your underwear and put on a gown. The dermatologist or provider will systematically examine your entire skin surface, including the scalp, ears, between the toes, under the nails, and the genitals, using a dermoscope to magnify suspicious areas. The exam typically takes 15–30 minutes. You should bring a list of any spots you want evaluated and note any that have changed. Most exam visits do not result in a same-day biopsy; the provider will advise on next steps for any concerning lesions.

Can I screen myself for melanoma at home?

You can perform a thorough skin self-exam at home, and monthly self-exams are strongly recommended for everyone, particularly for people at elevated risk. However, self-exam does not replace professional evaluation. A dermatologist with dermoscopy can evaluate lesions with much greater accuracy than the naked eye, identify subtle features not visible to you, and assess spots on areas of the body that are difficult to examine yourself (scalp, back, between the toes). Self-exam and professional exams are complementary tools.

How do I know if a mole is suspicious?

Apply the ABCDE rule: Asymmetry (one half doesn’t match the other), Border (irregular, notched, or poorly defined edges), Color (multiple shades within one lesion, brown, black, tan, red, white), Diameter (larger than 6 mm, roughly the size of a pencil eraser), and Evolving (any change in size, shape, color, or sensation over time). Also watch for the “ugly duckling” sign, a mole or spot that simply looks different from all your others. Any lesion that bleeds without trauma, itches persistently, or is new and growing warrants prompt evaluation.
