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.
