In the skin cancer ABCDE mnemonic, what does the D stand for?

Explanation:
The D in the ABCDE rule stands for diameter. It flags lesions that are larger than about 6 mm in diameter, roughly the size of a pencil eraser, as more likely to be melanoma and warrant closer evaluation. While size alone doesn’t diagnose cancer, this threshold helps clinicians decide when a mole should be examined sooner or biopsied. Remember the other clues: asymmetry, border irregularity, and color variation, with evolution (change over time) signaling increased concern. In this scheme, evolving is the aspect for E, while diameter is specifically the D.
