Most people have moles, and in many cases, they’re completely harmless. However, knowing how to recognize a mole that could be a warning sign of skin cancer—especially melanoma—is critical for early detection and treatment. At North Branch Dermatology LLC in Chicago, IL, we encourage patients to monitor their skin regularly using the ABCDE Rule, a simple but powerful tool for spotting potentially suspicious moles.

What Is the ABCDE Rule?

The ABCDE Rule is an easy-to-remember guideline that helps identify changes in moles that may require medical attention. Here’s what to look for:

• A – Asymmetry: One half of the mole does not match the other half in shape or size.
• B – Border: The edges are irregular, blurred, or jagged, rather than smooth and well-defined.
• C – Color: The mole has multiple colors or uneven shades of brown, black, red, white, or blue.
• D – Diameter: The mole is larger than 6 mm (about the size of a pencil eraser), though melanomas can be smaller.
• E – Evolving: The mole is changing in size, shape, color, or elevation, or it begins to itch, bleed, or crust over.

When to See a Dermatologist

If you notice any of these signs—or if a mole just doesn’t look or feel right—it’s time to schedule an evaluation with a board-certified dermatologist. Early detection of melanoma dramatically increases the chances of successful treatment, and a quick exam could make all the difference.

At North Branch Dermatology LLC, we provide comprehensive skin checks and mole evaluations. Our experienced dermatology team will examine any suspicious lesions and, if necessary, perform a biopsy to rule out skin cancer.

Why Regular Skin Checks Matter

Even if you don’t see any changes, regular skin exams are an essential part of preventive care. A yearly visit with your dermatologist helps catch skin cancer early, especially in areas you might not easily see—like your back or scalp.
