Moles are very common pigmented skin lesions that come in all shapes and sizes. Melanomas are pigmented skin cancers that are becoming more common in the UK population. The two can look very similar, so how do you know when a dark patch is something to be concerned about? A new mole appearing after the age of 30 should always be checked. They can develop after this age, but it’s unusual. The ABCDE rule is used by clinicians as a quick assessment of a pigmented lesion to determine the risk of it being a melanoma, but it can be used by anyone….
If you are concerned about a mole then consider the ABCDE rule:
A – Asymmetry
Is the mole symmetrical or not? Draw an imaginary line down the middle and see if the two halves are the same. If not, then that’s abnormal.
B – Border
Is the edge of the mole smooth or uneven? If it is not smooth then that is abnormal.
C – Colour
Is the colour of the mole even throughout? If not, then this is abnormal.
D – Diameter
Is the size of the mole greater than 7mm? If so, then this is abnormal.
E – Evolving
Is the mole changing? Does it bleed? If so, then this is abnormal.
If any of these abnormal findings are present then see a doctor immediately, as it could be a melanoma. Always follow a good skin care regime for protection against UV rays:
- Wear high factor sun cream (even on a cloudy day)
- Wear a wide-brimmed hat
- Cover up sun-exposed areas with long sleeves and a long skirt or trousers
- Avoid direct sun exposure between the hours of midday and 3pm
