How to spot the early signs of Melanoma

Awareness of Melanoma Graphic

Melanoma is the most dangerous form of skin cancer and can arise from existing moles or develop as a new growth.

Detecting melanoma early can lead to a more favorable prognosis.


Therefore, it's important to recognise the early signs.

ABCDE Rule of Melanoma

One common method used to identify suspicious moles is the ABCDE rule:

A – Asymmetry:

Normal moles are usually symmetrical. If you were to draw a line through a normal mole, the two halves would typically mirror each other. Melanomas often have an asymmetric shape, meaning the two halves don't match in size, shape, or colour.


B – Border:

The borders of an early melanoma can be uneven, scalloped, or notched.

Regular moles usually have smoother, more even borders.


C – Colour:

Multiple colours can be a warning sign.

While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan, black, red, blue, or white.


D – Diameter or Dark:

Melanomas usually have a diameter larger than the size of a pencil eraser (about 6 mm), but they may sometimes be smaller when first detected.

Additionally, regardless of size, any mole that is darker than others should be checked.


E – Evolving:

Look for moles that change in size, shape, colour, or elevation.

Also, take note of any new symptom like bleeding, itching, or crusting.

Other Signs and Symptoms

Apart from the ABCDE rule, the following can also be indications of melanoma:

Elevated or Raised Appearance:

Over time, melanomas can become elevated or raised from the skin surface.


Sores that don't heal:

If you notice a sore or spot that doesn’t heal, it may be a sign of melanoma or another skin cancer.


Spread of pigment:

If the pigment from the mole spreads to the surrounding skin, it's a red flag.


Redness or a new swelling:

Swelling beyond the mole's border or redness can indicate melanoma's progression.


Sensation changes:

Itchiness, tenderness, or pain in a mole can be a warning sign.


Surface changes:

Oozing, bleeding, or the appearance of a bump or nodule can be an indicator.


A spot that looks different from all the others:

Sometimes referred to as the "ugly duckling" sign, if a mole or spot stands out from others on your skin, it's worth having it checked.

Recommendations

Regular Self-Examinations:

At least once a month, examine your skin, especially after a change in appearance.

Use mirrors to check hard-to-see areas like your back, buttocks, and the back of your legs.


Professional Skin Examinations:

See a dermatologist at least once a year or as recommended.

They can spot potentially dangerous moles or spots that you might have overlooked.


Photographic Records:

Keeping photographic records of your moles can be helpful to track any changes over time.

AWARENESS IS THE KEY!

If you find a mole or growth that exhibits any of the signs above or seems suspicious, see a dermatologist as soon as possible.


Early detection and treatment significantly improve the prognosis for melanoma.

When we think about sunny days, beach outings, backyard barbecues, or even a casual stroll in the park, we often picture warmth, happiness, and the golden glow of sunlight. Yet behind this idyllic imagery lies a silent threat: ultraviolet (UV) radiation. Prolonged and unprotected exposure to UV rays is the leading cause of skin cancer, the most common cancer worldwide. While sunscreen plays a well-known role in defense, one equally vital yet sometimes overlooked method is wearing protective clothing.

Australia holds the unenviable title of having one of the highest rates of skin cancer in the world. With our sun-soaked climate and love of the great outdoors, it’s no wonder that skin health has become a national priority. And yet, too many people still overlook the signs their skin is sending them—signs that could spell the difference between early intervention and a serious health battle. Whether you’re checking your own skin at home or preparing for a visit to a specialist, understanding what to look for and when to act is crucial.

We all have them—freckles, spots, and moles that seem harmless. But what if one of those seemingly innocent marks holds the early signs of something more serious? Every year, thousands of people are diagnosed with skin cancer, and many of those cases could have been caught earlier—perhaps even prevented—through routine skin checks. In Australia, where sun exposure is a daily reality, the importance of regular skin checks cannot be overstated.

Skin cancer is one of the most common cancers globally, and among its many forms, melanoma is the most aggressive. Within the melanoma category, nodular melanoma stands out as one of the most dangerous and fast-growing types. Because it doesn’t always follow the usual warning signs of skin cancer, it's crucial to understand what it looks like, how it behaves, and what risk factors contribute to its development.
