Asymmetry
If you draw a line through the middle of the mole, do the two halves look different?
Benign moles are usually round or oval and look roughly the same on both sides. A suspicious mole may have one half that is noticeably different in shape, size, or color from the other.

Summary
The ABCDE rule is a widely taught dermatology mnemonic for spotting moles that may need professional evaluation. Each letter covers one visual or behavioral trait that distinguishes benign moles from potentially suspicious ones: Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, and Evolution (change over time). This tool walks you through each criterion one at a time, records your answers, and produces a clear summary so you can decide whether to see a dermatologist.
