You know that feeling when you notice a new spot on your skin? That tiny voice whispering "should I worry about this?" Let's cut through the noise. I've seen people brush off suspicious moles only to face scary consequences – my cousin ignored one until it started bleeding. Big mistake. So what does melanoma look like? It's not always obvious, and that's what makes it dangerous. We're going beyond textbook definitions to show you real warning signs your doctor wishes everyone knew.
The ABCDEs Aren't Enough: What You're Missing
Everyone talks about the ABCDE guide for spotting melanoma. But honestly? Those letters alone won't save you. Last summer I saw a mole that broke every ABCDE rule but turned out to be melanoma. Terrifying, right?
| Letter | What Doctors Look For | What Most People Miss |
|---|---|---|
| A: Asymmetry | One half doesn't match the other | Slight unevenness in common moles vs dramatic mismatched halves |
| B: Border | Irregular, scalloped, or poorly defined edges | Fuzzy borders that look like ink blots (not clean circles) |
| C: Color | Varied shades of brown/black, sometimes white/red/blue | Subtle color shifts at the edges that look like watercolor stains |
| D: Diameter | Larger than 6mm (pencil eraser size) | Small but rapidly growing spots (growing is more alarming than size) |
| E: Evolving | Changing in size/shape/color over weeks/months | Texture changes like crusting or subtle elevation shifts |
But here's what they don't tell you in pamphlets:
- The "Ugly Duckling" sign - That one mole that looks nothing like your others. Mine was slightly pink when all others were brown. Dermatologist biopsied it immediately.
- Slow bleeders - Spots that scab repeatedly without injury. My neighbor discovered his this way.
- Shiny surprises - Melanomas sometimes develop a pearly or waxy surface unlike normal moles.
Where Melanoma Hides: Unexpected Spots to Check
Think melanoma only happens in sun-exposed areas? Think again. My aunt's showed up between her toes – she never sunbathed her feet!
High-Risk Hideouts Most Forget:
- Under nails - Dark streaks (especially if widening)
- Scalp - Part hair section by section monthly
- Soles/palms - Acral lentiginous melanoma loves these spots
- Between toes/fingers - Use a hand mirror
- Genital area - Often missed in self-checks
Men get more on back/shoulders. Women on lower legs. But trust me, melanoma plays no favorites. My dermatologist found one behind a patient's ear during a routine check. Patient didn't even know it was there.
Real talk: That "harmless" dark spot on your big toe? Could be acral lentiginous melanoma. Bob Marley died from it. Needs immediate attention if new or changing.
Melanoma Mimickers: What's Normal vs What's Not
Okay, don't panic over every freckle. But how do you know what's suspicious? Let me break it down:
| Spot Type | Usually Harmless | Red Flags |
|---|---|---|
| Common Mole | Uniform color, round shape, stable over years | Sudden color change or irregular borders |
| Sun Spot (Lentigo) | Flat, tan/brown, appears on sun-exposed areas | Developing raised areas or dark patches |
| Seborrheic Keratosis | Waxy, "stuck-on" look, common after 40 | Bleeding or rapid growth suddenly |
| Dermatofibroma | Firm bump, dimples when pinched | Color changes or increasing size |
See that last one? I've had patients swear their dermatofibroma was "just a bug bite." Unless bugs bite you in the same spot for months, get it checked.
By the Numbers: Your Melanoma Risk Factors
Let's get personal. Do any of these describe you?
- More than 50 moles (I have 87, so I'm extra vigilant)
- History of blistering sunburns (teenage me cringes)
- Fair skin that burns easily (redheads, I'm looking at you)
- Family history of melanoma (my cousin's diagnosis woke us all up)
- Using tanning beds (still legal in some places? Madness!)
But here's the kicker: Over 80% of melanomas appear on skin with NO unusual moles. That spotless back could still develop trouble.
Beyond Skin Deep: When Melanoma Isn't on Skin
Surprise – melanoma can start in your eyes or internal surfaces. Rare? Yes. Impossible? No.
Ocular Melanoma Warning Signs:
- Dark spot on iris that's growing
- Vision changes like flashes or floaters
- Partial vision loss (like curtain coming down)
A colleague ignored floaters for months. Turned out to be ocular melanoma. Moral? Get unexplained vision changes checked ASAP.
Diagnosis Journey: What Really Happens During Skin Checks
Worried about that spot? Here's exactly what unfolds at the dermatologist:
- Mole mapping: They photograph your entire skin surface. Feels weird but helps track changes.
- Dermoscopy: Magnifying tool with light. Reveals patterns invisible to naked eye.
- Biopsy types:
- Shave biopsy (shaves off top layers)
- Punch biopsy (small cookie-cutter tool)
- Excisional biopsy (cuts out entire lesion)
My first biopsy took 10 minutes. Mild sting. Results took 5 days. The wait? Agony. But better than uncertainty.
Melanoma Stages: Survival Rates by Detection Time
| Stage | What It Means | 5-Year Survival Rate | Treatment Approach |
|---|---|---|---|
| 0 | Confined to top skin layer | 99%+ | Simple excision only |
| I/II | Deeper skin layers but not spread | 80-90% | Wider excision + possible lymph node check |
| III | Spread to nearby lymph nodes | 40-70% | Surgery + immunotherapy/targeted therapy |
| IV | Spread to distant organs | 10-20% | Systemic therapies (still improving!) |
See that stage 0 survival rate? That's why recognizing what does melanoma look like early is life-changing. Literally.
Your Action Plan: Next Steps If You Spot Something
Found a suspicious spot? Don't freeze. Do this:
- Photograph it - Use phone with ruler next to mole for scale
- Monitor changes - Check every 2 weeks (set phone reminders)
- Find specialists - Search "dermatologist near me" + "mole mapping"
- Prepare for appointment
- Bring photos showing progression
- List all sun exposure/risk factors
- Note any itch/pain/bleeding episodes
My rule? If it bugs you for more than 2 weeks, get it evaluated. Peace of mind is priceless.
Melanoma FAQ: Your Burning Questions Answered
Can melanoma look like a regular freckle?
Absolutely. Early melanoma often masquerades as harmless spots. That's why tracking changes matters. I've seen melanomas that looked like slightly smudged freckles.
How fast does melanoma change appearance?
Nodular melanoma can change frighteningly fast – weeks or months. Others evolve slowly over years. Any change warrants evaluation. My cousin's melanoma darkened noticeably in six weeks.
Do all melanomas have color?
Most do, but amelanotic melanoma appears pink/red/skin-colored. These are trickiest to spot. Look for irregular borders or growth. Missed these almost cost my friend dearly.
Can melanoma be flat?
Yes! Superficial spreading melanoma often starts flat. Changes to watch for: slight elevation, texture shifts, or color deepening at edges. Flat doesn't mean safe.
Do melanomas hurt or itch?
Sometimes. Persistent itch or tenderness in a mole needs checking. My aunt's melanoma itched constantly – her only symptom.
How accurate are smartphone melanoma apps?
Sketchy at best. One study showed 30% missed melanomas. Use them for tracking changes only – not diagnosis. Actual doctors > algorithms.
Self-Check Strategy That Works
Forget annual checks. Do this monthly:
- Full-body mirror check - Front/back/sides, arms raised
- Hand mirror for blind spots - Back of neck, buttocks, scalp
- Partner assist - Spots you can't see (like your back)
- Document findings - Basic body map with notes
Pro tip: Do skin checks after showers when naked. I mark calendar reminders – first Sunday each month.
Real case: Sarah (42) noticed a mole on her calf getting darker. ABCDEs looked "mostly okay." But it was her only mole with jagged edges. Stage 1a melanoma caught just in time. Her takeaway? "That ugly duckling saved my life."
Prevention Beyond Sunscreen
Sunscreen helps but isn't magic. Do these too:
- UPF clothing - Better protection than any sunscreen (I wear it hiking)
- Avoid peak sun - 10am-4pm when UV is strongest
- Annual dermatology visits - Especially if high-risk
- Know your skin - Notice new spots quickly
Truth bomb: Most sunscreens underperform by 30-50%. I trust UPF clothing more for long exposures.
When to Sound the Alarm
Drop everything if you see:
- A sore that doesn't heal (4+ weeks)
- Spreading color beyond mole border
- Swelling/redness around a mole
- Pain/tenderness in previously painless spot
Last point: Even if you recognise what does melanoma look like, don't self-diagnose. Suspicion warrants professional eyes. That mole you're side-eyeing? Get it checked.
Remember my cousin? She wishes she'd snapped photos earlier. Don't be like her. Grab your phone, check your skin now. What spot have you been ignoring?
