What are moles?
Moles are generally small, dark pigment spots on the skin caused by clusters of melanin-producing cells. "Most moles are harmless, but some can change over time, and these changes can be a sign of a cancerous mole," says Shwol-Huo (Danny) Kiang, DO, FAAD, Dermatology at ARC Medical Plaza Specialty in Cedar Park. "That's why it's good to be familiar with how moles can change and to know when it's time to consult a dermatologist."
Unusual moles that may indicate melanoma
A mole may be a sign of skin cancer if it has irregular borders, an asymmetrical shape, or if it changes in color, shape, size, or height. This ABCDE guide can help you remember what to watch for:
- Asymmetry: One half of the mole doesn't match the other.
- Border: The edges are irregular, ragged, or blurred.
- Color: The color is not uniform and may include different shades or patches.
- Diameter: The mole is larger than 6 millimeters.
- Evolving: The mole changes in size, shape, color, or begins to bleed or itch.
Signs to watch for
When monitoring moles, look for certain signs that could indicate a problem. A noticeable change in a mole's shape, size, or color should be taken seriously. A mole that becomes irregular or develops an uneven shape might be an early warning of melanoma, a dangerous form of skin cancer.
- Color: A mole that shows multiple shades or has lost its uniformity should be examined.
- Shape: Normal moles are round or oval, while irregular or uneven shapes may suggest something more serious.
- Size: Moles larger than a pencil eraser or those that continue to grow should be checked.
- Sensation: If a mole starts to itch, become sore, or cause irritation, it might be a concern.
- Texture: Changes in the surface of a mole, such as scaling or crusting, can be signs of a problem.
- Swelling: Any swelling or raised area around the mole should be noted.
- Bleeding: Moles that bleed or ooze should be examined by a physician.
If any of your moles meet one or more of these criteria, or if you notice any other concerning changes, consult a dermatologist. Early detection of skin cancer, particularly melanoma, can significantly increase the chances of successful treatment.
Preventing problems
To reduce your risk of developing cancerous moles, practice sun safety. Protect your skin by wearing sunscreen, avoiding excessive sun exposure, and covering up with clothing or hats when outdoors. Sunspots can develop from too much sun exposure, leading to changes in your moles over time.
Regular self-examinations and visits to a dermatologist are key to catching potential problems early. If you see a noticeable change of appearance in a mole, don't ignore it. Early detection is crucial for effective treatment and can make a significant difference in the outcome.
When to see a doctor
"It's essential to protect your skin and stay vigilant about changes in your moles," says Dr. Kiang. "If you notice any of the signs mentioned above, or if you're simply unsure about a mole, it's wise to consult a dermatologist. They can determine whether a mole is harmless or cancerous and recommend the appropriate course of action."
