How Often Should You Get a Skin Cancer Screening?

What affects how often you should be screened?

Risk-stratified screening is the current approach — a dermatologist sets a schedule based on your individual profile [1, 2].

Higher-risk factors that generally support annual or more frequent exams: - Personal history of melanoma, basal cell carcinoma, or squamous cell carcinoma - First-degree relative with melanoma - More than 50 to 100 moles, or atypical (dysplastic) moles - Very fair skin that burns easily - History of significant cumulative sun exposure, outdoor occupational exposure, or high-altitude living - History of indoor tanning bed use - Immunosuppression (organ transplant recipients or those on immune-suppressing medications have notably elevated risk for non-melanoma skin cancers)

Lower-risk individuals with no concerning history may be seen every one to three years, or as their clinician recommends after a baseline exam. The exam itself sets the interval — if a clinician finds concerning lesions or many atypical moles, follow-up becomes more frequent 1Ref 1US Preventive Services Task Force (2023).Skin Cancer: Screening (Final Recommendation Statement).Population-level screening evidence still evolving for average-risk adults; risk-stratified approach for higher-risk individuals; supports baseline exam recommendation.

The US Preventive Services Task Force notes that evidence on screening intervals for average-risk people in the general population is still evolving 1Ref 1US Preventive Services Task Force (2023).Skin Cancer: Screening (Final Recommendation Statement).Population-level screening evidence still evolving for average-risk adults; risk-stratified approach for higher-risk individuals; supports baseline exam recommendation. What remains clear is that people with risk factors benefit from regular professional evaluation.

What happens during a full-body skin exam?

A full-body skin exam (total body skin examination, or TBSE) is a systematic head-to-toe visual inspection by a clinician, typically a dermatologist. You will be asked to undress to a gown and the clinician will examine every skin surface — scalp, between the toes, and other covered areas.

The exam usually takes 15 to 20 minutes. For suspicious lesions, the clinician may use dermoscopy — a handheld magnifying tool with polarized light that improves detection accuracy beyond the naked eye alone.

A lesion that cannot be confidently cleared may be biopsied — a minor in-office procedure that sends a small skin sample to pathology for laboratory analysis. Biopsy is diagnostic, not a verdict — most suspicious-looking spots turn out to be benign.

For high-risk patients, total body photography creates a baseline photographic map of all lesions, making future change detection easier.

How to do a monthly self-skin check

Monthly self-examinations are recommended by dermatology societies for all risk levels. Use the ABCDE rule as a guide [3, 4]:

• A — Asymmetry: one half does not match the other
• B — Border: irregular, ragged, or blurred edges
• C — Color: variation in color within a single lesion (shades of brown, black, red, white, or blue)
• D — Diameter: larger than a pencil eraser (about 6 mm) — though melanomas can be smaller
• E — Evolving: any mole that is changing in size, shape, or color over weeks to months

Use a full-length mirror and a hand mirror for hard-to-see areas like the scalp, back, and backs of the legs. Taking consistent photos of your moles over time can help you detect subtle changes that are easy to miss.

Self-checks complement professional exams — they do not replace them.

When to see a dermatologist without waiting for a scheduled exam

Do not wait for a routine appointment if you notice:

• A mole or spot that is changing in size, shape, or color
• A sore that does not heal within a few weeks
• A spot that bleeds without being scratched or injured
• A pearly, shiny, or waxy bump on sun-exposed skin
• A flat, scar-like lesion that is pale or flesh-colored
• Any spot that looks very different from all your other moles (the 'ugly duckling' sign) 3Ref 3AAD Ad Hoc Task Force for the ABCDEs of Melanoma; Tsao H, Olazagasti JM, Cordoro KM, Brewer JD, Taylor SC, Bordeaux JS, Chren MM, Sober AJ, Tegeler C, Bhushan R, Smith Begolka W (2015).Early detection of melanoma: reviewing the ABCDEs.ABCDE criteria for self-skin examination and the 'ugly duckling' sign for atypical mole identification

Melanoma caught early is far more treatable than disease found late 2Ref 2Swetter SM, Tsao H, Bichakjian CK, Curiel-Lewandrowski C, Elder DE, et al. (2019).Guidelines of care for the management of primary cutaneous melanoma.Early detection of melanoma significantly improves outcomes; supports risk factor assessment and full-body exam approach. When in doubt, have it checked.

Skin cancer risk in darker skin tones

Skin cancer occurs in all skin tones. In people with darker skin, melanoma is more often diagnosed at a later stage — making awareness and self-checks equally important regardless of complexion. A clinician assesses suspicious lesions by texture, raised borders, and warmth, not only by redness or color change.
