What Are the Most Common Types of Skin Cancer?
1. Basal Cell Carcinoma (BCC)
What it is: The most common type of skin cancer, developing in the basal cells (lower layer of the epidermis).
What it looks like: A shiny bump, pearly nodule, or flat, scar-like area that may bleed or crust.
Where it appears: Face, neck, chest—places you’ve probably sun-kissed one too many times.
Risk factors: Fair skin, frequent sun exposure, history of tanning.
Statistics: Over 3.6 million BCC cases are diagnosed in the U.S. each year, accounting for 80% of all nonmelanoma skin cancers. Source
2. Squamous Cell Carcinoma (SCC)
What it is: A cancer of the squamous cells (the outer layers of your skin).
What it looks like: Rough, red patches, open sores, or wart-like growths that may itch or bleed.
Where it appears: Scalp, ears, lips, hands—areas exposed to the sun.
Risk factors: UV radiation, fair skin, older age, weakened immune system.
Statistics: About 1.8 million new SCC cases are diagnosed in the U.S. annually. The rate has increased 200% over the last 30 years. Source
3. Melanoma
What it is: The most serious form of skin cancer, originating in melanocytes (pigment-producing cells).
What it looks like: A new or changing mole with an irregular shape, multiple colors, or evolving size.
Where it appears: Common on the back, legs, arms, and face—but can develop anywhere, even under nails or on the scalp.
Risk factors: Intermittent sunburns, tanning beds, family history.
Statistics: An estimated 104,960 new melanoma cases will be diagnosed in the U.S. in 2025, with 8,430 melanoma-related deaths. Source
How to Recognize Skin Cancer Symptoms
Use the ABCDE rule to evaluate suspicious moles or spots:
A – Asymmetry: One side doesn’t match the other.
B – Border: Edges are uneven, ragged, or blurred.
C – Color: Multiple colors or shades in one mole.
D – Diameter: Larger than 6mm (about the size of a pencil eraser).
E – Evolving: Changes in size, shape, or feel.
Also keep an eye out for:
New growths that itch, bleed, or don’t heal
Any spot that’s different from others on your skin (the “ugly duckling” rule)
Skin Cancer in Women: Why It Matters in Your 30s and 40s
Many women assume skin cancer is something they’ll worry about later in life—but the truth is, melanoma is one of the most common cancers in women under 40. Your 30s and 40s are a critical window for prevention and early detection.
Even if you’re indoors most of the time or think you’re “not at risk,” here’s the reality:
UVA rays penetrate windows and clouds
Childhood sunburns increase risk decades later
Tanning beds—even just once—increase your melanoma risk by 20%
Top Prevention Tips: How to Lower Your Risk of Skin Cancer
Want to protect your glow and your health? Here are skin-cancer prevention tips that are actually doable:
1. Wear SPF Daily 🧴
Use a broad-spectrum mineral sunscreen with SPF 30+ every day—yes, even in winter or on cloudy days.
I talk all things sunscreen in THIS ARTICLE!
2. Avoid Peak Sun Hours ☀️
The sun’s rays are strongest from 10am to 4pm. If you’re outside, find shade, wear a wide-brimmed hat, or rock a UV shirt.
Pro-tip: Wait 10-15 mins before putting on your sunscreen to soak up that Vitamin D
3. Skip the Tanning Beds 🚫
They’re not “safer than the sun”—they actually increase your risk of both melanoma and nonmelanoma skin cancers.
4. Check Your Skin Monthly 🕵️♀️
Use a full-length mirror and handheld mirror to scan your body—don’t skip your scalp, soles, or between your fingers and toes.
5. See a Dermatologist Annually 📆
Just like a yearly physical, a skin check should be on your radar, even if everything seems fine.
Frequently Asked Questions About Skin Cancer
Q: Can people with darker skin get skin cancer?
Yes! While it’s less common, skin cancer in people with darker skin is often diagnosed later, making outcomes worse. Everyone should practice sun protection and check their skin.
Q: Is skin cancer always caused by the sun?
UV exposure is the biggest risk factor, but genetics, immune system status, and even certain medications can also play a role.
Q: How often should I check my skin?
Once a month is ideal. Use the same technique each time so you can spot changes easily.
