A melanoma does not always look like the dark, irregular mole shown in awareness campaigns. It may be a small spot that has changed quietly over months, a pink bump that will not heal, or a new mark on skin that receives little sun. These melanoma early detection examples are not a tool for diagnosing yourself. They are reasons to arrange a professional skin check without delay.
Australia has one of the world’s highest rates of skin cancer. Melanoma can spread to other parts of the body if it is not found and treated early, yet many melanomas can be treated very effectively when detected at an early stage. Every minute counts when a suspicious lesion is changing.
Melanoma early detection examples to recognise
The most useful question is not, “Does this look exactly like melanoma?” It is, “Is this spot new, changing, unusual for me, or different from the others?” A doctor with skin cancer expertise can examine the area properly, often using a dermatoscope, and decide whether monitoring, photography, biopsy or removal is appropriate.
A mole that is changing shape or colour
A common example is a mole that has been present for years but begins to change. It may develop a blurred edge, become asymmetrical, darken in one area, or show more than one colour, such as brown, black, grey, red or blue. Some people notice that a flat mole has become raised or that a previously even-looking spot now has an uneven surface.
The ABCDE guide can help you remember concerning changes:
- A – Asymmetry: one half does not match the other.
- B – Border: edges look irregular, notched, blurred or poorly defined.
- C – Colour: there are multiple colours or a new uneven colour pattern.
- D – Diameter: the spot is growing, particularly beyond about 6 mm, although smaller melanomas occur.
- E – Evolving: any change in size, shape, colour, elevation or sensation.
“Evolving” is often the most meaningful warning sign. A small lesion can still be serious if it is noticeably different from its previous appearance.
The ‘ugly duckling’ spot
Not every melanoma meets every ABCDE feature. Sometimes the warning sign is simply that one spot looks unlike the rest of your moles. For example, a person with many light-brown, round moles may develop one very dark, uneven lesion. Another person may notice a single new pink or red spot among otherwise stable freckles.
This is called the ugly duckling sign. Your skin has its own pattern. A spot that breaks that pattern deserves assessment, even if it is tiny, smooth or not painful.
A new spot after age 40
New moles can appear at any age, but a genuinely new pigmented spot in adulthood should not be dismissed. A melanoma may begin as a new flat brown, black or multicoloured mark that slowly enlarges. It can occur on the back, chest, legs, arms, scalp or face – not only on areas that burn easily.
If you notice a new lesion that remains after several weeks or appears to be growing, book a skin check. This is particularly important if you have fair skin, many moles, a history of sunburn, previous skin cancer or a close relative with melanoma.
A pink, red or skin-coloured lesion
Melanoma is not always brown or black. Amelanotic melanoma has little or no visible pigment and can look pink, red, skin-coloured or lightly raised. It may resemble a pimple, eczema, a bite, a harmless bump or a small sore.
One early detection example is a pink spot that repeatedly crusts, bleeds after minor contact, feels tender or fails to clear. Another is a firm red or pink nodule that is enlarging over a matter of weeks. Do not rely on colour alone when deciding whether to seek care.
A spot that itches, hurts, bleeds or will not heal
Many harmless skin lesions can itch or become irritated, especially in dry weather or where clothing rubs. Symptoms do not automatically mean melanoma. But a mole or spot that repeatedly itches, stings, bleeds, crusts or breaks down should be examined, especially when there has also been a visual change.
A lesion that does not heal is worth prompt medical review. It may be melanoma, another form of skin cancer, or a non-cancerous condition. Either way, guessing at home can delay the right treatment.
Melanoma can occur where you may not look
Regularly checking sun-exposed skin matters, but melanoma can develop in less obvious locations. Ask a partner, friend or clinician to help inspect your scalp, back and the backs of your legs. Use a mirror for hard-to-see areas, but do not let a difficult location become a reason to wait.
Melanoma can also occur under nails, on the palms of the hands, soles of the feet, between the toes, and in genital areas. A dark streak in one nail, particularly if it widens, becomes uneven or extends onto the surrounding skin, needs assessment. So does a changing dark patch on a palm or sole.
People with skin of colour are still at risk of melanoma and may be more likely to develop certain melanomas on the hands, feet or under nails. Lower rates do not mean no risk. Any changing or unusual lesion should be checked.
When to book a skin check
Arrange a prompt appointment if a spot is new and changing, stands out from your other moles, bleeds without a clear reason, or will not heal. You do not need to wait until a lesion is large, painful or dramatic. Melanoma can be symptom-free in its early stages.
A routine skin check can also be sensible if you have a personal history of melanoma or other skin cancers, a first-degree relative with melanoma, numerous moles, previous blistering sunburns, fair skin that burns easily, or substantial lifetime UV exposure. This includes outdoor workers, people who spend weekends on the water or sporting field, and those who have spent years working outdoors.
How often you need a skin check depends on your individual risk. A GP or skin cancer doctor can advise on an appropriate schedule. Between appointments, learn what is normal for your skin and report changes rather than waiting for your next planned review.
Take a clear photo, then seek clinical advice
A well-lit photo can help you notice whether a lesion has changed, particularly in an area that is hard to see. Include a date and, where practical, a reference such as a ruler beside the lesion. Photos are useful records, not a substitute for examination, and phone images cannot reliably rule melanoma in or out.
Avoid picking, burning, cutting or treating a suspicious spot with over-the-counter remedies. If a clinician recommends a biopsy, it is because looking at skin alone cannot always provide a definite answer. The pathology result guides the next step.
Sun protection remains essential: seek shade, wear protective clothing and a broad-brimmed hat, use sunglasses, and apply broad-spectrum SPF 50+ sunscreen correctly. These habits reduce UV damage, but they do not replace checking your skin. A lesion can still arise in someone who is careful in the sun.
If one of these examples sounds familiar, make the appointment. Most changing spots will not be melanoma, but the cost of ignoring the one that is can be far greater than a timely skin check. Knowledge can save your life.
