GP Dr Philippa Kaye previously told Sun Health: “It’s important to know your body and become familiar with your moles and skin and what they look like, so you will recognise if something changes,”
“See a doctor if you notice a mole is changing, which can be in colour, size, appearance but also in sensation - so if a mole is bleeding, crusty or becomes sore or itchy.”
WHEN SHOULD I SEE A GP?
Some melanomas develop from existing moles.
But the rest grow on what was previously normal skin.
You should see if you notice a:
- New abnormal mole
- Mole that seems to be growing or changing
- Change to a previously normal patch of skin
- A mole that is itching or painful
- A mole that is bleeding or becoming crusty
- A mole that looks inflamed
- Unusual mark or lump on your skin that lasts longer than a few weeks - especially if you are immunocompromised
- A dark area or line under a nail that is not due to an injury
