Have you ever spotted a mole or mark on your skin and wondered, “Is this normal?” You’re not alone. Skin cancer is the most common type of cancer in the United States, and early detection can make all the difference.

But what does skin cancer actually look like? The truth might surprise you.

Let’s break it down.

The ABCDEs of Melanoma

One of the most common and dangerous types of skin cancer is melanoma. Doctors use the ABCDE rule to help identify warning signs:

A - Asymmetry: One half of the mole doesn’t match the other.

B - Border: Edges are irregular, ragged, or blurred.

C - Color: A variety of colors like brown, black, red, or even blue in one spot.

D - Diameter: Larger than 6mm (about the size of a pencil eraser).

E - Evolving: Any change in shape, size, color, or feel.

Even if your mole doesn't check all five boxes, a change in any one of these areas could be reason enough to see a dermatologist.

Basal and Squamous Cell Carcinomas

These non-melanoma skin cancers are also common and tend to appear on sun-exposed areas of the body.

Basal Cell Carcinoma (BCC) often looks like:

A shiny bump or nodule.

A pink growth with raised edges.

A sore that heals and then returns.

A flat white, yellow, or waxy area that looks like a scar.

Squamous Cell Carcinoma (SCC) may show up as:

A red, scaly patch of skin.

An open sore that bleeds or crusts.

A raised growth with a central depression.

A wart-like bump that grows over time.

These types often develop slowly but can become serious if left untreated.

Hidden Spots You Might Miss

Think skin cancer only shows up on areas that get sun? Think again.

Skin cancer can appear anywhere — including under your nails, between your toes, on your scalp, or even in your eyes. These less visible locations are easy to overlook, which makes regular self-checks even more important.

So, What Should You Do?

If you notice a mole or skin change that:

Looks different from the rest,

Changes rapidly,

Or just gives you a bad gut feeling…

Don’t wait. Getting it checked could be lifesaving. Dermatologists often perform a quick, non-invasive skin exam and may recommend a biopsy if anything looks suspicious.

Final Thought: When in Doubt, Check It Out

Skin cancer doesn’t always scream for attention. Sometimes, it whispers — in the form of a small spot, a subtle change, or a persistent sore. Knowing what to look for is your first line of defense.

🧴 Remember: Sun protection and regular skin exams are your best allies.
