Your risk profile from skin type, history and exposure — plus the ABCDE self-check
| ABCDE | Watch for (any mole) |
|---|
Skin cancer is the most common cancer in America and the most survivable when caught early — Stage 1 melanoma has ~99% five-year survival versus ~35% once distant — which makes risk-knowledge and early detection nearly the whole battle. This assessment scores the established risk factors (skin type, burn history, tanning beds, moles, family history), assigns the screening cadence dermatology guidelines suggest for your band, and teaches the two self-check tools: ABCDE and the ugly duckling.
| Factor | Impact |
|---|---|
| Very fair skin (Fitzpatrick I–II) | Baseline vulnerability — least melanin shielding |
| Blistering sunburns in childhood | Each one raises lifetime melanoma risk; 5+ nearly doubles it |
| Tanning beds before 35 | +75% melanoma risk — WHO Class 1 carcinogen, same category as tobacco |
| 50+ moles or atypical moles | Strong independent predictor; the 'ugly duckling' rule matters most here |
| Family history (first-degree) | ~2× risk; earlier and more frequent screening |
| Prior skin cancer | The strongest single factor — recurrence surveillance is standard |
| Immunosuppression | Transplant recipients: up to 65–100× squamous-cell risk |
Two corrections to folk wisdom: darker skin doesn't confer immunity — melanoma in deeper skin tones is rarer but diagnosed later and deadlier (acral sites: palms, soles, nails — check them); and a "base tan" is not protection — it's ~SPF 3 of damage already done.
Most melanomas are found by patients or partners, not doctors. The method: monthly, good light, full mirror survey — front, back, sides, scalp (hair dryer helps), palms, soles, between toes, nails. Score every mole against ABCDE (the table above; E for Evolving outranks the rest) and flag any ugly duckling — the spot that doesn't match its neighbors. Photograph anything borderline; a photo a month settles "is it changing?" better than memory ever will. Anything evolving, bleeding, or new-and-different: dermatology appointment, and say the word "changing mole" when booking — it re-prioritizes triage.
Substantially — blistering burns before 18 are among the strongest melanoma predictors, decades later. You can't undo them; you CAN convert them into vigilance (they're why your screening band is higher) and protect the next generation's skin.
WHO Class 1 carcinogen; use before 35 raises melanoma risk ~75%, and risk scales with sessions. No cosmetic result justifies it — spray tans exist. This is the least ambiguous line in dermatology.
A 10-15 minute full-body visual exam (gown, systematic survey, dermatoscope on anything interesting), possibly photos for tracking, and a shave/punch biopsy only if something warrants it. Painless, covered by most insurance, and the appointment people postpone for years takes less time than lunch.
Basal (most common): locally destructive, rarely spreads, highly curable. Squamous: can spread if neglected. Melanoma (the dangerous one): spreads early, which is why every changing pigmented spot earns attention. All three prefer sun-exposed skin; all three are most curable early.
Acral sites: palms, soles, under nails (a new dark band in a nail deserves a visit), plus mucosal areas. Melanoma is rarer but found later in deeper skin tones — the mortality gap is a detection gap, closable by exactly this awareness.
The known, quantified harm is UV. Mineral options (zinc/titanium) exist for anyone concerned about chemical filters; the dermatologic consensus is unambiguous that any sunscreen beats none. The perfect-is-enemy-of-good trap kills more skin than any ingredient.
Yes — answers never leave your browser.
Know your band, keep the screening cadence, and give the mirror five minutes a month — the difference between skin cancer's best and worst outcomes is almost entirely who noticed first.
