What is a Mole?
A mole, or nevus, is a small skin growth that typically appears brown or black. Moles occur when skin cells called melanocytes cluster together instead of spreading evenly across the skin. Most moles emerge during childhood or teenage years and may change in size, shape, or color over time.
Causes of Atypical Moles
Atypical moles, also referred to as dysplastic nevi, differ from regular moles in appearance and may mimic melanoma, a serious form of skin cancer. Although their exact cause isn’t fully understood, contributing factors include:
- Genetics: A family history of melanoma or atypical moles significantly increases risk.
- Sun exposure: UV rays from sunlight or tanning beds can promote the development of irregular moles.
- Skin type: Fair-skinned individuals with light hair and eyes are more likely to develop atypical moles or skin cancer.
Symptoms of Atypical Moles
Atypical moles tend to be larger and more irregular than common moles. Key warning signs to watch for include:
- Asymmetry: One half of the mole does not mirror the other.
- Border: Edges that appear uneven, jagged, or poorly defined.
- Color: Uneven pigmentation or multiple colors within the mole.
- Diameter: A size exceeding 6mm, about the size of a pencil eraser.
