When should I see a doctor?

Make an appointment with a consultant if you notice any changes to your skin, such as a lump or sore that doesn’t heal, new marks or moles or changes to an existing mole. 

For existing moles, use the ABCDE method of evaluation changes as follows: 

• asymmetry – one half of your mole doesn't match the other

• border – the edges of your mole are irregular or uneven

• colour – your mole contains several colours or has changed colour

• diameter – your mole is larger than the size of a pencil eraser (6mm)

• evolution – your mole has changed size, shape, or colour over time or is itching, bleeding, or crusting
