Almost all of us will have at least one mole somewhere on our body.
Moles are a really common skin growth that appear as dark spots which may be flat or raised. They’re generally harmless, but in some people, sun exposure may pose certain risks. With summer quickly approaching, it’s crucial to understand how to look after moles in the sun and identify any abnormalities.
Why is the sun a risk factor?
Moles form when clusters of pigment-producing cells called melanocytes develop. These melanocytes are responsible for producing melanin, which gives skin its colour.
Sunlight contains ultraviolet (UV) rays. Regularly exposing skin and moles to the sun and these UV rays can damage the DNA of skin cells, which may trigger abnormal cell growth causing melanocytes to overproduce. This can lead to a skin cancer called melanoma.
Therefore, it’s vital to monitor moles throughout sun exposure, as well as take precautions to minimise risks.
Spotting changes in moles
Moles may change colour, shape, or size in the sun. The ABCDE rule is a helpful guide to identify whether any changes may be signs of potentially cancerous moles:
- A = Asymmetry: Healthy moles are generally symmetrical, whereas cancerous moles might look more uneven.
- B = Border: Moles should have smooth, even borders. Blurred, irregular or lumpy edges might be a cause for concern.
- C = Colour: The colour of moles should be consistent. Watch out for moles that change colour in the sun or start to have varying shades. Moles may also get darker in sunlight, which is a sign of skin cancer.
- D = Diameter: Moles which get bigger in the sun are more likely to be cancerous.
- E = Evolving: As well as any changes to the size, shape, and colour, watch out for any itching, bleeding, or texture changes.
Protecting moles in the sun
Completely avoiding the sun is almost impossible, but there are steps you can take which may minimise the risks associated with exposing moles to the sun.
Reduce time in the sun: Try to practise spending time out of the sun during hours where UV rays are the strongest (typically between midday and 3pm), and make sure to regularly seek shade throughout the day.
Protect your skin: Ensure you frequently apply sunscreen and wear a hat to keep your face protected. If possible, try to wear loose, light clothing which can cover up moles from the sun.
Perform regular skin checks: Examine your skin regularly to look for any mole changes or new appearances. Talk to a dermatologist if you notice anything unusual and want to get a professional mole check.
Consider mole removal treatment: Mole removal is usually not necessary, but some people decide to remove moles for cosmetic reasons, or if they are causing discomfort or discontentment. Additionally, it is likely that a dermatologist would recommend a mole removal treatment if any changes occur which indicate signs of potential cancer.
