Ask A Skin Doctor: ABCDE Mole Check

Dear Doctor

Just want to check this mole.

Dear Patient

Malignant melanoma, which is a type of skin cancer, can resemble moles.

To identify a malignant melanoma, the following ABCDE mole check rules have been developed:

ABCDE Mole Check

A Asymmetry

This means that the lesion does not have a uniform appearance when both its sides are compared.

Your mole does not seem to have a nice, round uniform shape.


B Borders

The borders of a melanoma are usually uneven and ragged.

Your mole does not have nice smooth borders.


C Color Variation

Melanomas tend to have color variations with different shades of brown, black, red and blue.

Your mole seems to have different shades of brown and black in the cener with a lighter halo around it though it is hard to say whether that is due to the lighting.


D Diameter

Melanomas are usually larger than 6 mm when first discovered.

I do not know the size of your mole but you can measure it at home.


E Evolving

Melanomas usually change in size, color, shape and even begin bleeding or getting itchy or painful.

Only you can answer if your mole has been changing since you first noticed it.


In view of these findings I suggest you consult your nearest dermatologist and get it examined.
