(HealthDay News) -- If you're trying to figure out if you have an ordinary mole or a skin patch that could be cancerous, the American Academy of Dermatology offers these tell-tale signs of an ordinary mole:
- It's generally only one color, commonly brown, pink, red, blue, black or flesh-colored.
- It's symmetrical, meaning one side is shaped the same as the other.
- It's flat or only slightly raised from the skin.
- It seldom changes in appearance.
If you have an unusual patch of skin that doesn't fit these descriptions, visit a dermatologist without delay.
