Moles to Look Out For: Changes That Need Attention

Look for a mole that becomes uneven from side to side, develops an irregular edge, or shows several shades rather than one consistent colour. A spot that grows, becomes raised, crusted, itchy, tender, or bleeds without clear injury also warrants assessment. These signs do not by themselves diagnose melanoma; a clinician needs to examine the mole and decide whether sampling is appropriate.

Arrange a skin examination and describe when you first noticed the change. Take a clear photograph in good light to help you track its appearance, but do not rely on photographs instead of an examination. Avoid picking, cutting, burning, or applying home removal products. If removal is recommended, the tissue may be sent for laboratory assessment so the diagnosis is based on cells rather than appearance alone.

Book an appointment promptly for a changing, bleeding, persistently sore, or repeatedly crusting mole. Seek quicker advice if a dark mark changes rapidly, a wound does not heal, or bleeding continues after gentle pressure. A new or changing spot on an area that is difficult to see, including the scalp or back, is also worth showing to a clinician.

Ask whether the mole can be assessed with a dermatoscope, whether it should be monitored or removed, and how the site should be cared for if it is excised. You can also ask when to return for a skin check and which changes should trigger an earlier review.
