If you notice a changing facial mole or patch, it’s important to seek a dermatologist’s review promptly to rule out skin cancer.
What to look for in a changing mole
Monitor moles or patches for the following signs, often remembered by the ABCDE rule:
- Asymmetry: one half looks different from the other
- Border: irregular, blurred, or jagged edges
- Colour: uneven shades or unusual colours (black, brown, red, white, or blue)
- Diameter: larger than 6mm (about the size of a pencil eraser)
- Evolving: changes in size, shape, colour, or texture over time
When to see a dermatologist
If your mole shows any of the ABCDE signs, it’s essential to consult a dermatologist. Other warning signs include:
- Itching, bleeding, or crusting
- A mole that looks different from others on your body
Practical takeaway
Perform a monthly self-check of your skin using a mirror or ask someone to help. Take clear photos of any suspicious moles to track changes over time. If you notice any concerning changes, book an appointment with a dermatologist immediately.
