What are moles?
Moles are small, dark marks that appear on your skin. They are usually round or oval in shape and can sometimes be raised from the skin. Most people have about 50 moles.
Most moles are harmless but some types can develop into skin cancer. This is usually caused by long periods of exposure to the sun.
It is important to watch your moles to prevent skin cancer. Talk to your doctor if your mole changes or if you get a new mole after the age of 25.
If you have a mole you should:
- avoid scratching or picking it – keeping children’s finger nails short and trimmed may help stop them scratching their moles
- if your mole is in a vulnerable area where it could be knocked or scraped against something, you should try to protect it
Checking your moles
It’s important to look out for any changes to the shape, size and colour of your moles. Check your moles regularly and look out for the following:
- changes to the size and shape of your moles
- any changes to the colour of a mole – look out for moles that have several colours or shades
- any bleeding, soreness, itching or inflammation
- a crusty or flaky appearance developing
- new moles which look different or unusual.
