Why checking moles is so important
The reason why it’s important to check your moles is that they can change in to a type of cancer called melanoma. Melanoma is the third most common skin cancer in the UK. The good news is, the earlier it’s spotted and treated, the better the outlook is.
Know your risk of skin cancer
Firstly, think about whether you’re more likely to develop skin cancer than other people. Most people know that getting sunburn increases the chances of getting skin cancer. But there are other things that increase your risk too, including if you:
- have fair hair and eyes, lots of freckles or pale skin that burns easily
- expose your skin to the sun every now and again, rather than most of the time
- use a sun bed
- have lots of moles – more than 11 moles on your right arm means you’re likely to have more than 100 moles on your whole body
- have large moles bigger than 6mm
- have had a melanoma before, or if a close relative has had one
- are taking medicines that affect your immune system
How to check your moles
There are no hard and fast rules for how often you should check your moles. But if you tick a number of things on the list above then it’s a good idea to check yourself once a month. The better you get to know your skin, the more likely you are to see any changes.
- Stand in a well-lit room.
- Use a full-length mirror and a hand mirror to check your body all over.
- Make sure you check hard to see places such as your back, buttocks and scalp. If you have a partner, they can check moles in these places for you as well.
- Check the less obvious places too, like your underarms, in between your fingers and the soles of your feet.
What you’re looking for when you check your moles
You’re looking for new moles, or changes in the size, colour or shape of an existing mole. There’s a useful way of remembering what to look for; the ABCDE. It stands for:
- A – Asymmetry. Do both halves of the mole look the same?
- B – Border. Is the edge of the mole uneven or blurred?
- C – Colour. Is the mole a mix of different shades or colours?
- D – Diameter. Is it bigger than 6mm from side to side? (As a tip, the end of a pencil is about 5mm across)
- E – Evolution. Has the mole changed?
There are a few other important things to look out for: itching and bleeding or crusting. If a mole starts to bleed and you haven’t injured it then you should get it checked as soon as you can.

What to do if you’re worried about a mole
If you’re worried about any of your moles then you should always get them checked by a doctor. You can make an appointment to see your GP, and if needed, they can refer you to a clinic at your local hospital. Or you may choose to have your moles checked privately.
Whether you have two or two hundred moles, it’s important to take care of your skin. Always seek shade in the middle of the day, wear a long-sleeved top, trousers, a hat and sunglasses and use a high protection sunscreen. And keep checking those moles too!
