Suspicious moles

How and what to look for

How to find suspicious moles

These characteristics are used by dermatologists to classify melanomas. Look for these signs: Asymmetry, irregular Borders, more than one or uneven distribution of Colour, or a large (greater than 6mm) Diameter. Finally, pay attention to the Evolution of your moles - know what's normal for your skin and check it regularly for changes.

If you see one or more of these, make an appointment with a dermatologist immediately.  Please note that not all melanomas fall within the ABCDE parameters so visit your dermatologist regularly to catch any potential issues early.

ABCD rules for Melanoma

While monitoring moles and birthmarks on your skin you should ask yourself these 4 questions. This will help you identify suspicious moles and know when to go to a dermatologist.

A - Asymmetry 
Is the birthmarks shape asymmetrical?
One side of the birthmark should e similar or identical to the other side
however suspicious birthmarks are often asymmetrical.
B - Border
Is the birthmarks border line uneven?
Birthmarks border line should not be “ragged” or have notches.
C - Color
Does the birthmark have multiple colours?
Suspicious birthmarks have often multiple colour variations such as brown, black, blue, sometimes also red and white.
D - Dynamics
Has the birthmark changed recently?
If your birthmark has evolved bigger or changed colour in the last few months or a year then you have to tell that to your doctor.

One or multiple signs of suspicious moles does not automatically indicate, that this mole has melanoma. The ABCD rules are just a framework to quickly identify moles, which should be looked at. Dermatologists use this rule all the time and so should you. If you find a suspicious mole you should contact your Dermatologist or go to the next clinic where they can perform a Dermtest. If you visit a dermatologist personally, make sure the doctor uses a dermascope when looking at your suspicious mole.
