Types of Skin Cancer: What You Need to Know from a Dermatologist

Learn the differences between common skin cancers and why early detection by a dermatologist in Mesa AZ can help protect your health.

Let’s face it: sunshine is one of Arizona’s biggest perks. But while those golden rays feel great on your skin, they can carry a darker side: skin cancer. And if you live in Mesa, basking might be part of your daily routine. That’s why understanding skin cancer isn’t just a nice-to-know, it’s a must-know.

At Summit View Dermatology, we see skin cancer cases almost daily, and early detection truly makes all the difference. If you’re not sure what sets Basal Cell Carcinoma apart from Squamous Cell Carcinoma or why Melanoma is such a big deal, don’t worry, you’re in the right place.

Let’s break it down together, step by step.

Basal Cell Carcinoma: The Most Common Type of Skin Cancer

This is the big one. Basal Cell Carcinoma (BCC) is the most common (and fortunately, the least dangerous) form of skin cancer. That said, it’s still cancer, and it still needs your attention.

What it looks like:

  • Waxy, pearly bump
  • Flat, flesh-colored or pinkish patch
  • May bleed or scab and never fully heal

Where it shows up:

  • Sun-exposed areas like the face, ears, neck, and shoulders

What causes it:

  • Chronic, cumulative sun exposure over time

Why it matters:

BCC rarely spreads to other parts of the body, but it can grow deep and affect nearby tissues and nerves if left untreated. A dermatologist in Mesa AZ can easily diagnose and treat it, usually with a simple in-office procedure.

Squamous Cell Carcinoma: More Aggressive, Still Treatable

Next up, Squamous Cell Carcinoma (SCC). It’s the second most common skin cancer and a bit more aggressive than BCC. SCC can spread, especially when diagnosed late, so early detection is vital.

What it looks like:

  • Scaly red patch or bump
  • Crusty, thickened skin that may bleed
  • May resemble a wart

Where it shows up:

  • Common in areas with frequent sun exposure: scalp, hands, lips, ears

What causes it:

  • UV radiation from long-term sun exposure or tanning beds

Why it matters:

Unlike BCC, SCC carries a higher risk of spreading to the lymph nodes or internal organs if not treated promptly. Luckily, an experienced dermatologist, especially one familiar with Arizona’s intense sun exposure, can diagnose and treat SCC early with excellent success rates.

Melanoma: The Most Dangerous Skin Cancer

Melanoma is the rarest of the big three, but it’s also the deadliest. It develops from melanocytes, the pigment-producing cells in your skin, and it tends to spread quickly if ignored.

What it looks like:

  • An asymmetrical mole
  • Borders that are irregular or blurred
  • Colors that vary from brown to black, red, or even blue
  • A diameter larger than a pencil eraser
  • Evolving: changing in size, shape, or color

(Mnemonic tip: Just remember ABCDE: Asymmetry, Border, Color, Diameter, Evolving!)

Where it shows up:

  • Often appears on the back, legs, arms, or face
  • Can also form in places with little or no sun exposure like under nails or on the soles of your feet

What causes it:

  • Intense, intermittent sun exposure and a history of sunburns
  • Genetics can play a role too

Why it matters:

Melanoma spreads rapidly and can be life-threatening if not caught in time. If you notice a suspicious mole, don’t wait, schedule a skin check with a skilled dermatologist in Mesa AZ immediately. Treatment typically involves surgical removal, and in more advanced cases, may include immunotherapy or chemotherapy.

Other Types of Skin Cancer You Should Know

Though rarer than the others, there are a few additional skin cancers worth mentioning:

  • Merkel Cell Carcinoma – A fast-growing, aggressive cancer that often appears as a painless, firm bump.
  • Dermatofibrosarcoma Protuberans (DFSP) – A slow-growing tumor that can invade surrounding tissue.
  • Sebaceous Carcinoma – Originates in oil glands and is more common around the eyes.

Any new, unusual, or changing skin lesion deserves a professional look. You don’t have to play the guessing game.

When Should You See a Dermatologist in Mesa AZ?

Living in a high UV index area like Mesa means your risk of skin cancer is significantly higher than someone living in, say, the Pacific Northwest. That’s why regular skin exams are so important, even if you think that little spot is “just a freckle.”

It’s time to see a dermatologist if:

  • You have moles that look irregular or change over time
  • A sore won’t heal or frequently bleeds
  • You notice rough, scaly patches
  • You have a personal or family history of skin cancer
  • You’ve had frequent sunburns or used tanning beds in the past
