Moles

Also called Naevi or Nevi

Moles are small, coloured spots on the skin made of clusters of pigment cells. Most people have between 10 and 50. They can be flat or raised, and they may change slowly over the years, appear or fade. Most moles are harmless, but a change in a mole can be a sign of melanoma skin cancer.

What it is

Moles do not need treatment unless there is concern about cancer, or for cosmetic reasons.

Checking your skin regularly and protecting it from the sun help. A mole that changes in size, shape or colour should be checked.

Common signs

  • Small brown, black or skin-coloured spots
  • Flat or raised
  • Usually round or oval with a smooth edge

How it is usually diagnosed

  • Examination with a dermatoscope
  • Removal and testing if there is concern

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Photos of moles over time
  • Dermatology letters
  • Histology reports of removed moles

Questions to ask your doctor

  • Does this mole need to be checked or removed?
  • How often should I check my skin?
  • Would mole mapping help me?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A mole that is changing, bleeding, itching or growing: get it checked soon
