At North County Dermatology Center in Encinitas, CA, Dr. David Thomas and Dr. Margaret Dupree provide expert skin evaluations to help patients monitor mole changes and reduce the risk of skin cancer. While most moles are harmless, changes in their appearance can sometimes indicate a more serious condition. Recognizing these changes early is critical, as skin cancer, including melanoma, is highly treatable when detected at an early stage.

What Are Moles?

Moles, or nevi, are groups of pigmented skin cells that can occur anywhere on the body. They are different sizes, shapes, and colors, and most of them appear during childhood and adolescence, but some may develop later in life because of sun exposure or genetics. While most moles do not change over time, watching them for any abnormality, particularly as you age, is necessary.

When to Be Concerned About Mole Changes

Not all changes in moles are dangerous, but certain features may signal a risk of skin cancer. The "ABCDE" rule offers a helpful guide:

• Asymmetry: One half of the mole does not match the other.
• Border: The edges are irregular, blurred, or notched.
• Color: The mole has uneven shades of brown, black, red, white, or blue.
• Diameter: The mole is larger than 6 millimeters, though melanomas can be smaller.
• Evolving: The mole changes over time in size, shape, color, or texture, or begins to itch, bleed, or crust.

If you notice these signs, promptly scheduling a skin evaluation with a dermatologist is important.

Risk Factors for Skin Cancer

Several factors increase your risk for skin cancer, including excessive sun exposure, previous sunburns, light skin, numerous or abnormal moles, family history of melanoma, and a weakened immune system. Understanding your risk factors enables you to take an active role in protecting your skin.

The Importance of Regular Skin Checks

Regular self-examination and a once-a-year skin examination by a dermatologist are necessary for early detection. With a mirror, look at your whole body, including hard-to-reach areas like the scalp, back, and soles of the feet. If you notice a new mole or change in an existing one, it's always wise to have it checked out.

What to Expect During a Skin Exam

At a skin checkup at North County Dermatology Center, your dermatologist will thoroughly examine your skin for worrisome moles or lesions. If a worrisome mole is found, a biopsy may be recommended to determine if cancer is present. Early detection means more effective and less invasive treatment options, which may involve surgical excision or topical therapy based on the case.

Protecting Your Skin

Preventing skin cancer starts with everyday habits. Use a broad-spectrum sunscreen with SPF 30 or higher, seek shade during peak sun hours, avoid tanning beds, and wear protective clothing outdoors. Teaching children to practice sun safety is also critical, as early sun protection can significantly lower their lifelong risk.
