Most skin moles are harmless, but some may develop into melanoma – the deadliest form of skin cancer. Knowing how to recognize suspicious changes can save your life. The most widely used method is the ABCDE rule.
ABCDE rule for skin moles
- A – Asymmetry: one half of the mole differs from the other
- B – Border: irregular, jagged or blurred edges
- C – Color: uneven, multiple shades of brown, black, red or white
- D – Diameter: larger than 6 mm
- E – Evolving: any change in size, shape or color over time
Risk factors for melanoma
- fair skin, light hair and eyes
- history of severe sunburns (especially in childhood)
- more than 50 moles on the body
- family history of skin cancer
- tanning bed use
- weakened immune system
Dermatoscopy – the gold standard
Dermatoscopy is a non-invasive technique that allows dermatologists to examine moles in detail using a special magnifying device with polarized light. It significantly increases diagnostic accuracy.
Prevention
- use SPF 30+ sunscreen daily
