Melanocytic Nevus (Mole)

Mole

Overview

Melanocytic nevi (moles) are benign clusters of melanocytes (pigment-producing cells) that appear as small, colored spots on the skin. Most adults have between 10 and 40 moles. While the vast majority are harmless, monitoring for changes is important since melanoma can develop from or mimic a mole.

Key Symptoms

• Small, round or oval spots on the skin
• Uniform color — usually brown, tan, or skin-colored
• Smooth, well-defined borders
• Flat or slightly raised surface
• Typically less than 6 mm in diameter
• May slowly change in appearance over decades

1. Perform monthly self-skin checks using the ABCDEs: Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolving.
2. Protect moles from sun damage with sunscreen and protective clothing.
3. See a dermatologist promptly if a mole changes size, shape, color, or starts itching or bleeding.
