The most common symptoms of melanoma are:
- a new spot on the skin, or a spot that is changing in size, shape or colour
- moles that have features of the ABCDE rule:
- asymmetry – the 2 sides of the mole do not match
- border irregularity – the mole has irregular edges
- colour – the mole is not the same colour throughout
- diameter – the mole is wider than about 6 mm (although some melanomas are smaller than this)
- evolving – the mole has changed in size, shape, colour or texture during the past few weeks or months
- a sore that does not heal
- itching, scaling, bleeding, oozing, swelling or pain in a mole
- spread of pigment from a spot into the surrounding skin.
Many conditions can cause these symptoms, not just melanoma. If you have any of these symptoms, talk to your doctor.
