The ABCD Rule
If you notice any of the following signs, then see your doctor without delay.

- Border – the edges of your mole are irregular, blurred or jagged
- Colour – the colour of your mole is uneven, with more than one shade
- Diameter – your mole is wider than 6mm in diameter (the size of a pencil eraser)
