One indication that a mole might be cancerous is that it ______.

• A. Is symmetric
• B. Has uniform color
• C. Is growing larger on one side than another
• D. Bleeds easily

Answer: (C)

Asymmetry is a strong warning sign. When a mole grows unevenly, so one side becomes larger or shapes diverge, the two halves no longer mirror each other. That uneven growth reflects irregular, uncontrolled cell activity that is characteristic of malignant changes. In contrast, benign moles tend to be symmetric, with smooth, even borders and a uniform color. Bleeding can occur with various skin issues, but it’s not as reliable a signal as asymmetry for suggesting a mole might be cancerous. So the best indicator here is the appearance changing to an asymmetric shape, signaling the need for professional evaluation.
