Almost everyone has moles. Most of the time they are completely innocent. Also a change in a mole is usually harmless. Nevertheless, it is wise to consult your doctor or dermatologist if a mole changes. Troubled moles can be precursors to skin cancer.


A normal or changing birthmark should not:

  • Grow
  • Change in colour or appearance, which include different shades of pigmentation, redness in the birthmark, but also the disappearance of pigmentation
  • Change its shape
  • Itch, sting, or become painful
  • Develop crusts
  • Bleed

One or more of these characteristics does not necessarily mean that it is a malignant mole. However, it is advisable to have this assessed by a dermatologist.
