Mole or suspicious spot

Concerned about a mole? Have a dermatologist assess it.

Has a spot changed? Does it look different from your other moles? Or do you keep looking at it?

Upload your photos via the app and have the spot checked by a BIG-registered dermatologist, within 12 to 48 hours. No referral needed, from €39. It does not count towards your Dutch deductible (eigen risico).

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.

How it works.

  1. Upload photos via the app

    Take sharp photos of the spot, up close and from a short distance.

  2. Review by a dermatologist

    A BIG-registered dermatologist reviews your photos within 12 to 48 hours.

  3. Assessment and a clear next step

    You receive the dermatologist's assessment of the spot. Is a physical examination, dermatoscopy or tissue analysis needed? Then the dermatologist tells you exactly what the next step is.

Every review is done by a BIG-registered dermatologist. No algorithm and no assistant: a specialist looks at your photos personally.
