Early Signs Of Melanoma How To Identify Melanoma

Melanoma is the most serious form of skin cancer. It can spread very quickly and become deadly. But the good news is, if it’s found early, there’s a higher chance of effective treatment and recovery. That’s why knowing the early signs of melanoma is so important. Read on to ensure you know what to look for when you’re checking your skin.

The most obvious warning signs of melanoma are changes to your skin or moles: how they look or how they feel. These changes aren’t generally accompanied by pain, so early warning signs can go unnoticed if you’re not vigilant about checking your skin regularly and booking annual skin checks. In fact, recent studies in the US found that 56.3% of melanomas detected by American Dermatologists had not been noticed by the patient1, which is why it pays to book a professional skin check every year.

How To Identify Melanoma What Is A Normal Mole 2

Above: there are many types of 'normal' moles - this makes identifying the signs of melanoma more difficult

Moles – what’s normal?
Most moles appear when we’re children or young adults. In general, normal moles are:
- Evenly-coloured brown, tan or black
- Flat or raised on the skin
- Round or oval
- Most often, less than 6 millimetres across.

Once developed, a mole usually stays the same size, shape and colour for many years. However, your skin is constantly changing, so if you notice a mole that appears later in life – make sure you get it checked out.

Check for changes – early and often

The most important warning signs of melanoma are any new spots on the skin or ones that change. If you notice any variations such as a change in size, shape or colour, it could suggest a melanoma may be developing. Our MoleMap Melanographers are highly trained in detecting the signs of early melanoma, so if you’re concerned, give us a call us on 0800 665 362.

Above: learning the A.B.C.D.E. rule can help us identify the early signs of melanoma

Remember the A.B.C.D.E. rule
The A.B.C.D.E. rule is a simple guide to checking for the early signs of melanoma. Look out for the following:

Asymmetry – The shape of one half does not match the other.

Border – The edges are often ragged, notched, blurred, or irregular in outline; the pigment may spread into the surrounding skin.

Colour – The colour is uneven. Shades of black, brown, and tan may be present. Areas of white, grey, red, pink, or blue also may be seen.

Diameter – Size changes and usually increases. Typically, melanomas are at least 6mm in diameter (the diameter of a pencil).

Evolving – look for new moles or changes to any moles.

The E.F.G. rule

The E.F.G. rule is another guide that recognises a type of melanoma known as nodular melanoma. It can grow very quickly so early detection and treatment is vital. So check your skin regularly, or better still book an expert skin check.

If you are checking your skin yourself, look out for:

Elevated: Moles that are raised on the skin.

Firm: Moles that are firm to touch.

Growing: Moles that grow and change very rapidly.

Moles don’t need to be dark or have any other colour to them, but the key giveaway is that they are raised, often very symmetrical, are firm to touch, and most importantly are changing/growing progressively. In the early stages, this change might just be a sense of change rather than visible – perhaps the mole is itchy, or just feels funny.

This type of melanoma can affect anyone, but is generally much more common in men over 50. The frightening thing about nodular melanoma is that because they grow fast, they can go deep very quickly (within a few months), which is why they are so dangerous and need early diagnosis and removal.

Other signs to check for...

Just to make checking your skin even trickier, melanoma doesn’t always fit the ABCDE or EFG rules. If you notice a mole or skin lesion (abnormal spot) that is...

  • different from others (the 'Ugly Duckling')
  • changing in shape, size or colour
  • a new skin lesion, or
  • itches or bleeds

... you should bring it to the attention of your doctor or call us on 0800 665 362 immediately, accurately describing the symptoms and your reason for concern.

How can you spot melanoma yourself?
Learn how to check your skin regularly and get to know your skin well. It’s a good idea to do a self-check at least every three months (at the beginning of each season is an easy way to remember). Use a small mirror to check all areas, freckles and moles – and if possible, ask someone to check the areas you can’t see, such as your neck, scalp and back.

If you spot any changes or you’re concerned about a mole or sunspot, see your GP or book a skin check with MoleMap immediately, or give us a call on 0800 665 362. It may not be anything of concern, but it’s always best to get it checked out by experts.
