The ABCDE checklist helps differentiate between a normal mole, a seborrheic keratosis (benign growths) and a melanoma.

  • Asymmetry: melanomas have two very different halves and an irregular shape
  • Border: melanomas have an uneven or ragged border
  • Colours: melanomas will be a mix of two or more colours
  • Diameter: melanomas are larger than 6mm (1/4 inch)
  • Enlargement or elevation: a mole that grows over time or is raised is more likely to be a melanoma.
