Pictures of abnormal moles

See pictures of abnormal moles that might be developing into melanoma skin cancer and also pictures of melanomas.

The pictures are just a guide and if you are worried about any moles or skin changes it is important to see your doctor to get them checked.

Dark mole

The photo below shows a very dark mole. Darkening is one possible sign that a mole is becoming cancerous and could be a melanoma. This mole is about a centimetre across.

Inflamed mole

The photo below shows a mole that has an area of inflammation around it. The inflamed area is about 7 millimetres at its widest but you can see that the original mole is much smaller than that.

Inflammation is another sign that a mole may be developing into a melanoma and needs to be checked out by a doctor.

Melanoma with irregular border

The photo below shows the irregular outline of a melanoma. Normal moles are usually much rounder, with smooth borders.

Melanoma with irregular shape and colour

Below is a very small melanoma. It is only about 4 or 5 millimetres across. But you can see clearly that it is not the same colour throughout. It also has an irregular shape. Irregular colour and shape are signs that should be checked by a doctor.
