TL;DR: Key Takeaways
- Skin cancer happens in all skin tones — Bob Marley died of acral melanoma under his toenail
- Black Americans have 75% 1-year melanoma survival; white Americans have 92%
- Melanoma in skin of color most often appears on palms, soles, under nails, and in the mouth
- Most screening advice and dermatology training has historically focused on fair skin
- ScanSkinAI is trained on diverse skin tones and validated across all Fitzpatrick types
The Quietest Disparity in American Skin Health
Walk into almost any pharmacy and look at the skin cancer awareness pamphlets. The photos are almost exclusively of pink-tan skin with brown moles. Search "what does melanoma look like" online — same. Look at the sample images in most dermatology textbooks — same.
That visual gap has real consequences. Melanoma in Black Americans has a 1-year survival rate of 75%, compared to 92% for white Americans. By 5 years, the gap is even wider. The risk of developing melanoma is lower in skin of color — but the risk of dying from it, once diagnosed, is dramatically higher.
Why Outcomes Are Worse — Not Because Risk Is Higher
The disparity isn't about biological vulnerability. It's about three compounding gaps:
- Awareness gap: Many people of color don't believe they're at risk for skin cancer
- Visual gap: Standard 'how to spot melanoma' guides show fair-skin lesions, not the lesions that actually appear in darker skin
- Training gap: Studies show many dermatology residents receive limited training on lesions in skin of color, leading to delayed diagnosis
The result is that melanoma in Black, Hispanic, and Asian Americans is more often diagnosed at stage III or IV — where treatment is more aggressive and survival drops sharply.
Where Melanoma Actually Appears in Skin of Color
The most common type of melanoma in darker skin tones is acral lentiginous melanoma, which appears in less-pigmented locations:
- Palms of hands and soles of feet (most common)
- Under fingernails or toenails (the famous Bob Marley case)
- Between fingers and toes
- Inside the mouth, on the tongue, or on lips
- Genitalia and anal area
These are not the locations most awareness campaigns focus on. They're not the locations most people self-check. And many primary care physicians don't routinely examine them either.

What to Look For — Skin of Color Edition
- A new dark spot on a palm, sole, or under a nail
- A dark vertical streak (longitudinal melanonychia) under a fingernail or toenail
- A non-healing sore on the foot, especially in people with diabetes
- A mole that's changing in size, shape, or color
- Any pigmented spot inside the mouth or on the tongue
The general ABCDE rule still applies — but for skin of color, location matters more than for fair skin. You're looking for the right things in different places.
The 'CUBED' Rule for Acral Melanoma
For nail and foot lesions, dermatologists use the CUBED criteria:
- C — Coloured lesions where any part is not skin colour
- U — Uncertain diagnosis after initial examination
- B — Bleeding lesion or any history of bleeding
- E — Enlargement of an existing lesion or ulcer despite therapy
- D — Delay in healing of any lesion beyond 2 months
Any spot meeting two or more CUBED criteria warrants urgent dermatology review.
What Needs to Change — and What You Can Do Today
The medical community is making progress: more diverse imagery in training materials, dedicated atlases of skin of color (like Dr. Susan Taylor's work), and AI tools explicitly trained on diverse populations. But change is slow, and the awareness gap closes one person at a time.
If you have skin of color: do monthly self-checks that include palms, soles, nails, and mouth. If you have a primary care physician, ask them to examine your feet at your annual visit. And use AI screening tools designed for diverse skin — not just the ones built on fair-skin training data.
Skin Cancer Risks by Specific Population
Black Americans
Lifetime melanoma risk is roughly 1 in 1,000 (vs. 1 in 38 for white Americans), but melanoma is more aggressive when diagnosed. Acral lentiginous melanoma accounts for 30–60% of melanomas in Black Americans (compared to under 5% in white Americans). Squamous cell carcinoma — particularly in scars, chronic wounds, and areas of chronic inflammation — is the most common skin cancer overall. Black women face elevated SCC risk in non-sun-exposed areas including the genital and perianal region.
Hispanic / Latino Americans
Melanoma incidence in Hispanic Americans has been rising faster than any other ethnic group in the US over the past 20 years. Acral and mucosal melanomas are over-represented. Hispanic patients are more likely to be diagnosed at later stages than non-Hispanic white patients. Many Hispanics fall into Fitzpatrick III–V — meaning they tan rather than burn but are still vulnerable to UV damage.
Asian Americans
Melanoma incidence is low but mortality is comparatively high — again because diagnosis is often delayed. Acral lentiginous melanoma is the most common subtype across East Asian, South Asian, and Southeast Asian populations. Routine examination of palms, soles, and nails should be standard for Asian American patients but rarely is.
Indigenous and Native populations
Native American, Alaska Native, and Pacific Islander populations face specific patterns including high SCC rates (Alaska Native populations have notable lip and oral SCC linked to traditional smokeless tobacco use) and limited access to specialty dermatology care.
Common Skin Conditions in Skin of Color That Get Misdiagnosed
Beyond cancer, many benign and inflammatory skin conditions look different in darker skin and are frequently missed or misdiagnosed:
- Post-inflammatory hyperpigmentation (PIH) — dark patches after acne, cuts, or eczema
- Keloid scars — raised, firm, often itchy scars more common in skin of color
- Vitiligo — patches of pigment loss, more visually striking on darker skin
- Hidradenitis suppurativa — painful nodules in skin folds, often misdiagnosed as boils
- Pseudofolliculitis barbae — razor bumps from curly hair regrowth
These aren't cancers but they affect quality of life and self-image — and they highlight why skin care needs to be tailored, not generic.
Building a Self-Check Routine for Every Skin Tone
- Monthly: 5-minute full-body check including palms, soles, scalp, between toes, under nails, mouth, and genital area
- Use a hand mirror or partner for areas you can't see
- Photograph any pigmented spot you want to monitor — compare month to month
- AI scan: any new spot, any nail streak, any non-healing sore
- Annually: see a dermatologist if you have darker skin AND any of: family history of melanoma, history of organ transplant, chronic non-healing wound, or unusual nail or palm/sole pigmentation
The Bottom Line
Skin cancer in skin of color is real, deadly, and underdiagnosed — but the solutions are simple. Know where to look. Check monthly. Use tools and clinicians who understand diverse skin. The 1-year survival gap between Black and white melanoma patients should not exist — and a single behavior change (checking palms, soles, and nails) can close most of it.

Frequently Asked Questions
Yes. While the risk is lower than in fair-skinned populations, skin cancer absolutely occurs in Black, Hispanic, Asian, and other people of color. Melanoma in skin of color is often diagnosed at a later, more dangerous stage — and 5-year survival is significantly worse.
Melanoma in skin of color most commonly appears on areas with less pigment: palms, soles of feet, under nails (acral lentiginous melanoma), and inside the mouth. Bob Marley's death from acral melanoma under his toenail is the most well-known example.
Black Americans have a 1-year survival rate for melanoma of 75%, versus 92% for white Americans. The gap is driven by later-stage diagnosis (because the melanoma appears in less-checked locations), lower awareness, and historic gaps in dermatologic training around darker skin.
Yes — especially if you have darker skin. Acral melanoma is the most common type of melanoma in Black, Hispanic, and Asian populations. Check palms, soles, between fingers and toes, and under fingernails monthly.
AI tools historically have struggled with darker skin tones due to under-representation in training data. ScanSkinAI is trained on diverse skin tones and explicitly designed to perform across all Fitzpatrick types — see our clinical validation page for accuracy data by skin type.
