In melanoma detection using the ABCDE rule, what does the 'D' stand for?

• A. Diameter
• B. Asymmetry
• C. Border irregularity
• D. Evolution

Answer: (A)

Diameter is the D in the ABCDE rule for melanoma detection. It flags lesions that are relatively large, with about 6 millimeters as a common threshold; anything at or above that size tends to raise concern and prompt closer evaluation. This criterion sits with the other features—asymmetry, border irregularity, and color variation—that collectively guide suspicion. Evolution, the other criterion, notes changes in the lesion over time. So a mole that’s growing or reaches roughly 6 mm in diameter should be examined further.
