How to tell if that mole is dangerous

Font Size:

We asked Dr Richard Shaffer, a consultant oncologist, to share the key early warning signs of melanoma, and how to tell when a mole should be checked by a doctor.

What exactly are moles and are they always harmful?
“Moles are small, coloured spots on the skin,” explains Dr Shaffer. “In most cases, they are usually nothing to worry about, but it’s always worth monitoring them in case they change shape, size and colour (or all three), as this could be a sign they are cancerous.”

How can I check my moles at home?
While there is no set way to check your moles, Dr Shaffer says it is always good to monitor any new moles or changes to an existing one. “The better you know your skin and the signs to look out for, the more likely you’ll spot any changes,” he says. “When checking your moles at home, stand in a well-lit room with a full-length mirror. It’s also worth having a hand mirror available to make sure you’re checking your body all over.”

Dr Shaffer says you shouldn’t forget to check the difficult to see places such as your back and scalp too. “If you’re struggling, perhaps ask a partner or family member to have a look at these for you,” he suggests. He stresses to check less obvious places, such as your underarms, the bottom of your feet and in between your fingers.

“Basically, you’re looking for new moles, or changes to the size, colour or shape of an existing mole,” says Dr Shaffer. The A-B-C-D-E method is a simple way of checking your skin tags, he adds.

A is for asymmetrical. “Do both halves of the mole look different?”

B is for the border. “Is the edge of the mole uneven or blurred?”

C is for colour. “Is the mole a mix of different shades or colours?”

D is for diameter. “Is it bigger than 6mm from side to side?” (Tip: the end of a pencil is about 5mm across.)

E is for evolving. “Has the mole changed?”

If the answer is yes, Dr Shaffer says it may be worth speaking to a doctor to get the mole checked.

Is there anything else I should look for?
Dr Shaffer says most normal skin moles resemble one another, whereas melanomas often stand out from the rest. “You should also look out for itching and bleeding or crusting. If a mole starts to bleed and you haven’t knocked or injured it, you should get it checked as soon as you can,” he adds.

What if my mole is cancerous?
If caught early enough, there are treatments available, and survival rates are high, says Dr Shaffer. “Knowing the signs and symptoms of skin cancer is imperative, especially if you work outside or spend long periods of time in the sun.”

The bottom line, Dr Shaffer says, is that if you notice any unusual changes to an existing mole or a newly formed one, you should make sure to get it checked by your doctor, who’ll be able to advise if you need further treatment.

Do you go for regular skin checks? Do you check moles yourself so that you know if they have changed?

    Go and see the doctor periodically for skin checks, wife saw a spot on my back years ago and it sometimes changed. Finally I went to have it checked – 2 days later I had a good portion cut out on my back as it was a malignant melanoma.
    Anybody living in Australia in the 50s and 60s should check their skin, we used to smear Coppertone on our torsos and fried in the sun. Where I live, all the young ones are doing the same as we did, not with Coppertone but something a bit more expensive. We lost a few cricketers to that disease.
