Another early warning sign of skin cancer is what is known as an “ugly duckling”.
Harker explained: “This is when a mole, blemish or skin lesion looks different the other moles or blemishes around it and stands out from the other moles.
“It can be raised, ooze or be sore, varying in colour or have an asymmetric edge.”
Follow the ABCDE rule to identify an ugly duckling.
A – Asymmetry: Look for moles that are asymmetrical in shape, where one half of the mole is unlike the other.
B – Border: Does the mole have an irregular border? Is it scalloped, jagged or poorly defined?
C – Colour and Comparison: Does the mole have more than one colour and does the mole look different to your other moles?
D – Diameter: Check the diameter of the mole to see if it is bigger than 7mm (about the size of the end of a pencil).
E – Evolving: Is the mole evolving or changing size shape or colour?
