When should you have a spot checked?

It changes in shape, colour or size.
It looks different from your other moles.
It itches, bleeds, hurts or does not heal well.
It is new and you don't trust it.

The ABCDE method

The ABCDE method can help you check a mole:

AAsymmetry

One half is shaped differently from the other.

BBorder

The border is irregular, ragged or blurred.

CColour

Several colours or shades within one spot.

DDiameter

Larger than 5 mm across.

EEvolution

The spot changes in shape, colour or thickness.

Change is often the most important signal. A smaller spot can also be a reason to have it checked.

Good to know.

Do I need a referral?

What does having a mole checked cost?

A review starts from 39 euros. You pay for the consult yourself, and your health insurance excess stays untouched.

How quickly do I get the result?

Within 12 to 48 hours, depending on the consult you choose. If you want a faster answer, choose a consult with a shorter response time.

What if the spot turns out to be suspicious?

Do the photos show that further examination is needed? Then the dermatologist explains why, and you are referred where necessary for a physical assessment, dermatoscopy or tissue analysis. Only after that can it sometimes be established with certainty what the spot is.
