early detection

The first signs of malignant melanoma are a change in colour and/or enlargement of a mole, freckle or birthmark. However, some melanomas may arise from normal looking skin.

A mole, freckle or birthmark can change in colour by becoming darker (dark brown/purple/black), developing new colours or even losing colour and becoming pink or whitish.

A mole, freckle or birthmark can also change by increasing in size by spreading across the skin or becoming raised and lumpy.

These changes are normally noticed over a period of several weeks or months rather than days.

Look for:
  • Recent appearance
  • Increase in size
  • Change in colour
  • Change in shape
  • Irregular border
  • Persistent itch
  • Recurrent bleeding
If you do find a mole, freckle or spot that is of concern make an appointment to see your doctor as soon as possible.

Body mapBody map
The use of a simple diagram or body map (pdf, 94kb) may be a useful aid when you are doing a self check of your skin. If you have any moles or lesions which you want to keep a close check on simply map them on the diagram, include the date and any other comments. 

Refer to the body map the next time you are conducting your skin check. If you notice any changes see your doctor as soon as possible. If you are unsure that a change is occurring a digital photograph repeated after two months may be helpful.

The majority of melanomas are detected solely by their appearance.

If you find anything unusual, see your doctor right away. Remember, the earlier a melanoma is found, the better the chance for a cure.
