Which diameter value is considered benign in the screening material?

• A. <5-6 mm diameter
• B. 1-2 cm diameter
• C. 10-12 mm diameter
• D. 2-3 cm diameter

Answer: (A)

In screening for pigmented skin lesions, smaller size is generally less concerning. The threshold most commonly used is around 6 millimeters in diameter; lesions smaller than this, when other features are not suspicious, are often considered benign in screening materials. Among the options, a diameter under about 5–6 mm fits that benign range best. The larger sizes (1–2 cm, 10–12 mm, 2–3 cm) are more likely to raise concern and warrant closer evaluation. Remember that size is only one factor—shape, border, color, and recent change also matter—but for benign designation, under 5–6 mm is the key cutoff.
