A melanoma can begin as a small new spot or a subtle change in an existing mole, often without pain or other symptoms. That is why melanoma survival rates are so closely tied to when the cancer is found. When melanoma is diagnosed before it has spread, treatment is often straightforward and outcomes are very good. When assessment is delayed, the situation can change quickly.

For Australians, this is a particularly urgent message. Australia has one of the highest rates of melanoma in the world. High UV exposure, outdoor work and recreation, fair skin, a personal or family history of melanoma, and a tendency to dismiss a changing spot can all add to risk. Knowledge can save your life, but it needs to lead to action.

Melanoma survival rates in Australia

Survival statistics describe what happened to large groups of people diagnosed with a cancer. They cannot predict exactly what will happen for one person. Your outlook depends on the melanoma itself, your overall health, the treatment available and how early the cancer is diagnosed.

Australian cancer data shows that around 94% of people diagnosed with melanoma survive at least five years after diagnosis. This is a strong overall figure, and it reflects improvements in early detection, surgery, follow-up and treatment. However, an average can hide an important reality: melanoma found early has a substantially better outlook than melanoma that has reached lymph nodes or distant organs.

Five-year survival does not mean a person only lives for five years. It is a standard measure that compares the survival of people with melanoma with the expected survival of people in the wider population over that period. Many people treated for an early melanoma are cured and live long, healthy lives.

Statistics also lag behind current care. They are based on people diagnosed in earlier years, while treatments and clinical approaches continue to improve. For people with advanced melanoma, newer immunotherapy and targeted therapies have changed treatment options considerably. Your treating team is the right source for information that applies to your diagnosis.

Why stage changes the outlook

Stage describes how far melanoma has progressed at the time of diagnosis. Doctors use the results of a biopsy, pathology testing, examination and, where needed, scans or lymph node assessment to determine it.

Localised melanoma

A localised melanoma is confined to the skin where it started. It has not been found in nearby lymph nodes or elsewhere in the body. Most early melanomas can be treated by surgically removing the cancer along with a margin of surrounding skin.

Thickness is one of the most important details in the pathology report. In general, thinner melanomas have a lower risk of spreading than thicker ones. Ulceration, where the skin over the melanoma has broken down, can also affect staging and prognosis. A thin melanoma removed early is very different from a thicker lesion that has had time to grow unnoticed.

Regional melanoma

Regional melanoma has spread beyond the original skin site to nearby lymph nodes or nearby skin and lymphatic channels. Treatment may involve surgery, drug therapy, radiation therapy in selected circumstances, or a combination of approaches.

A diagnosis at this stage is serious, but it is not a reason to assume there are no effective options. Specialist melanoma teams can assess the particular pattern of spread and recommend treatment designed to reduce risk and control the disease.

Distant or metastatic melanoma

Metastatic melanoma means cancer has spread to organs or lymph nodes away from the original site. This is the most advanced stage and carries a lower average survival rate than localised disease. Yet averages do not tell the whole story. Some people respond very well to modern immunotherapy or targeted treatment, sometimes for prolonged periods.

The central lesson is not to panic over statistics. It is to avoid giving melanoma extra time to progress. Every minute counts when a suspicious lesion needs medical assessment.

Factors that affect an individual prognosis

Stage matters, but clinicians look beyond stage alone. The depth of the melanoma, whether it is ulcerated, its location, whether lymph nodes are involved and whether all cancer was removed are all relevant. The type of melanoma can matter too, including less common types that may occur under nails, on the soles of the feet or in other less sun-exposed areas.

Age and general health can influence which treatments are suitable, but melanoma can affect adults of any age. It is a dangerous myth that young people do not need skin checks or that darker skin eliminates melanoma risk. People with skin of colour can develop melanoma, including on palms, soles, nail beds and mucosal surfaces. Diagnosis may be delayed when these risks are overlooked.

A previous melanoma also increases the chance of developing another melanoma. Ongoing professional checks and regular self-examination are therefore part of long-term care, even after successful treatment.

Early detection is the part you can influence

You cannot change every melanoma risk factor. You can, however, act promptly when something on your skin is new, changing or unusual. A skin check is not about trying to diagnose yourself. It is about giving a trained clinician the chance to examine a concerning lesion with the appropriate tools and decide whether it needs monitoring, imaging, biopsy or removal.

Pay particular attention to a mole or spot that changes in size, shape, colour or elevation. Also seek assessment for a lesion that looks different from your other spots – sometimes called the “ugly duckling” sign – or one that itches, bleeds, crusts, becomes tender or does not heal.

Melanoma does not always fit the classic picture of a dark, uneven mole. It can be pink, red, skin-coloured, blue-grey or even appear as a mark beneath a nail. Do not wait for a spot to become painful. Many melanomas are painless in their early stages.

If you notice a suspicious change, arrange a GP or skin cancer clinic appointment promptly. If a lesion is changing rapidly, bleeding without a clear reason or looks markedly different, make the appointment a priority. A photograph may help you track a change, but it is not a substitute for a clinical assessment.

What happens after a suspicious spot is checked

During a skin check, the clinician will ask about the lesion, your sun exposure, previous skin cancers and family history. They may use a dermatoscope, a magnifying device with specialised lighting, to inspect structures beneath the skin surface that cannot be seen clearly with the naked eye.

If the spot is concerning, the next step may be a biopsy or complete excision. The sample is examined by a pathologist, who confirms whether it is melanoma and provides details such as thickness and ulceration. Those details guide the treatment plan.

Waiting for pathology results can be stressful. Ask your clinician when to expect the result, who will contact you and what the next steps may be. If melanoma is confirmed, you may need a wider excision to remove additional skin around the original site. Depending on the melanoma’s features, your doctor may discuss specialist referral and testing of nearby lymph nodes.

Prevention still matters after a skin check

No sunscreen or behaviour can guarantee that melanoma will never occur, but reducing UV exposure remains one of the strongest ways to lower risk. In Australia, use sun protection whenever the UV Index is 3 or above: slip on protective clothing, slop on broad-spectrum SPF50+ sunscreen, slap on a broad-brimmed hat, seek shade and slide on sunglasses.

Sunscreen is essential, but it is not permission to stay in intense sun for longer. Reapply it regularly, use enough to cover exposed skin and combine it with clothing and shade. Avoid deliberate tanning and never use solariums. Children need consistent protection too, as sun damage accumulates over time.

People at higher risk may benefit from scheduled full-body skin checks. This can include people with many moles, fair or freckled skin, a history of severe sunburn, immune suppression, previous skin cancer or a close family history of melanoma. The right interval varies, so ask a clinician what is appropriate for you.

A changing spot is not something to watch for another season. Booking a skin check now can turn uncertainty into a clear plan – and, if melanoma is present, provide the early treatment that gives survival the best possible chance.
