Checking your own skin is nerve-wracking. You’re standing in front of a bathroom mirror, twisting your neck to see a spot on your shoulder that wasn’t there last summer, and honestly, your mind immediately goes to the worst-case scenario. You start scrolling through endless pictures of different types of skin cancer online, trying to match that tiny brown speck to a high-resolution medical photo. It’s a rabbit hole. Most of those clinical photos look nothing like what’s on your arm.
The reality is that skin cancer is a master of disguise. It doesn’t always look like a giant, bleeding ulcer. Sometimes it’s just a patch of dry skin that won't go away or a pearly bump that looks like a stubborn pimple. If you’re looking at pictures of different types of skin cancer to self-diagnose, you need to know that lighting, skin tone, and location on the body change everything.
Basal Cell Carcinoma: More Than Just a Bump
Basal Cell Carcinoma (BCC) is the most common form. It’s the "good" one, if you can even call cancer good, mostly because it grows slowly and rarely spreads to your lungs or brain. But it can still be destructive if you let it sit.
When you look at BCC in photos, you’ll usually see a "pearly" quality. It looks almost translucent, like a little wax bead stuck under the skin. You might see tiny blood vessels—doctors call these telangiectasias—branching out across the surface like little red spider webs.
It’s sneaky.
Sometimes a BCC just looks like a scar that appeared out of nowhere. Or it might be a flat, scaly, flesh-colored patch. On people with darker skin tones, about half of BCCs are pigmented, meaning they look brown or black, which makes them very easy to mistake for a normal mole. According to the Skin Cancer Foundation, BCCs often bleed after minor trauma, like towel-drying your face, and then they seem to heal. Then they bleed again. That "sore that won't heal" is the classic red flag.
Why Squamous Cell Carcinoma Often Gets Ignored
Squamous Cell Carcinoma (SCC) is the second most common type. If BCC is pearly, SCC is often crusty.
Think about a patch of skin that feels rough, like sandpaper. You pick at it, it scabs over, but it stays rough. That’s often how SCC starts. These typically show up on "high-exposure" areas. Your ears. The rim of your balding scalp. Your lower lip.

SCC can look like a thick, wart-like growth. In pictures of different types of skin cancer, SCC often appears as a firm red nodule or a flat lesion with a scaly surface. Unlike BCC, SCC has a higher risk of spreading to lymph nodes if it’s ignored, especially if it’s on the mucous membranes or the ears.
There’s also something called Actinic Keratosis (AK). These are precancers. They are basically the "orange alert" of skin health. If you see a photo of someone with many small, crusty, red or brownish spots on their forehead, those are likely AKs. Left alone, they have a localized habit of turning into SCC.
The Melanoma Problem: Beyond the ABCDEs
Melanoma is the one everyone fears. For good reason. It’s aggressive.
You’ve probably heard of the ABCDE rule: Asymmetry, Border, Color, Diameter, and Evolving. It’s a solid framework, but it doesn't cover everything. Some melanomas don't follow the rules.
Amelanotic melanoma is the perfect example of why pictures of different types of skin cancer can be misleading. These tumors lack melanin. They aren't dark. They’re pink, red, or clear. They look like a harmless skin tag or a bug bite. Because they don't look "scary," people wait months to get them checked. By then, the cancer might be deep.
Then there is Acral Lentiginous Melanoma (ALM). This shows up on the palms of the hands, soles of the feet, or under the nails. It’s the most common form of melanoma in people of color. Remember Bob Marley? That’s what he had. It started as a dark spot under his toenail that he thought was a soccer injury.

Merkel Cell and Rare Variants
We don't talk about Merkel Cell Carcinoma (MCC) much because it’s rare, but it’s incredibly fast-growing. It usually looks like a firm, painless, shiny nodule. It can be red, blue, or skin-colored.
The problem with MCC is that it looks like a cyst or a stye. If you see a bump that is growing rapidly—doubling in size in just a few weeks—that is a medical emergency. Don't wait for it to hurt. Skin cancer rarely hurts in the beginning.
Skin Tone Matters in Diagnosis
Medical textbooks have historically done a terrible job of showing skin cancer on dark skin. This is a massive problem.
On darker skin tones, Squamous Cell Carcinoma is actually the most common type. It often shows up in areas that aren't exposed to the sun, like the legs or feet, or in areas with chronic scarring or inflammation.
When you're looking at pictures of different types of skin cancer on Black or Brown skin, you aren't always looking for redness. You're looking for:
- Darker patches that are itchy or painful.
- Bumps that are darker than the surrounding skin.
- Changes in old scars.
- New growths in the groin or underarms.
Dr. Adewole Adamson, a dermatologist and researcher, has pointed out that the "sun exposure" narrative can sometimes lead to a false sense of security for people with more melanin. While UV protection is important for everyone, the way cancer manifests is structurally different across the population.
The "Ugly Duckling" Method
Instead of just staring at one spot, look at the whole "family" of moles on your body.

Most of your moles probably look alike. They’re the same shade of tan, the same oval shape. If you have one spot that looks totally different—the "Ugly Duckling"—that’s the one that needs a biopsy. Even if it doesn’t look like the scary pictures of different types of skin cancer you saw on a Google image search, the fact that it’s an outlier is significant.
Technology and the Biopsy
Don't trust an app.
There are plenty of AI-powered apps where you take a photo and it tells you if you’re safe. The tech is getting better, but it’s not there yet. A 2020 study published in The Lancet Digital Health found that these apps are often inconsistent, especially with rare cancers or atypical presentations.
The only way to know for sure is a biopsy. A dermatologist will numb the area and take a tiny piece of tissue. It’s fast. It’s mostly painless. And it’s the only way to get a definitive "yes" or "no."
Actionable Steps for Your Skin Check
Stop scrolling through Google Images and do this instead:
- Get a full-body map. Go to a dermatologist once a year. They have a tool called a dermatoscope—it’s basically a high-powered magnifying glass with polarized light—that sees structures under the skin surface that are invisible to the naked eye.
- Use your phone for good. If you see a suspicious spot, take a photo of it next to a ruler or a coin for scale. Take another photo every month. If it changes shape, color, or height, you have proof for your doctor.
- Check the "hidden" spots. Use a hand mirror for your back, but don't forget between your toes, your scalp, and even your fingernails.
- Check your "birthday suit" on your birthday. It’s an easy way to remember to do a self-exam.
- Focus on texture. If a spot feels different—scaly, hard, or "crusty"—it’s worth a professional look, even if the color looks normal.
- Trust your gut. If a spot just "feels" wrong or keeps catching on your clothes, get it frozen off or biopsied.
Looking at pictures of different types of skin cancer is a starting point for awareness, but it’s not a diagnosis. Skin cancer is highly treatable when caught early. If you're worried enough to be searching for photos, you're worried enough to book an appointment.
Immediate Next Steps:
- Perform a self-exam tonight using a full-length mirror and a hand mirror for your back and the back of your thighs.
- Identify any "outliers"—spots that don't look like your other moles or lesions that have changed in the last three months.
- Find a board-certified dermatologist and schedule a "Total Body Skin Exam." If you have a specific spot of concern, mention it when booking so they can prioritize the appointment.
- Protect your skin moving forward with broad-spectrum SPF 30+ and UPF-rated clothing, especially during peak UV hours between 10 AM and 4 PM.
