A spot that bleeds after a shower, a scaly patch that never quite heals, or a mole that has changed over months can be easy to explain away. In Australia, that delay can be dangerous. Skin cancer in Australia is extremely common, but early assessment gives people the best chance of simpler, more effective treatment.

Australia’s high UV levels mean sun damage is not limited to beach days or people who deliberately tan. It can build up during work, sport, school runs, gardening and everyday time outdoors. Knowledge can save your life, especially when it leads to a timely skin check.

Why skin cancer in Australia needs attention

Australia has one of the highest rates of skin cancer in the world. Around two in three Australians will be diagnosed with skin cancer by the age of 70. Most skin cancers are linked to exposure to ultraviolet, or UV, radiation from the sun, although other factors affect individual risk.

The good news is that many skin cancers can be successfully treated, particularly when detected early. The difficult part is that early skin cancer may not hurt, itch or look alarming. A lesion can appear small and harmless while growing beneath the surface or spreading to nearby tissue.

Melanoma is the form people often fear most because it can spread to other parts of the body. It is less common than non-melanoma skin cancers, but it causes a significant share of skin-cancer deaths. Basal cell carcinoma and squamous cell carcinoma are more common. They are often highly treatable, but should never be ignored: squamous cell carcinoma can spread, while basal cell carcinoma can cause substantial local damage if left untreated.

The changes worth checking

You know your skin better than anyone else. A new spot or a spot that is changing, unusual or simply not healing deserves clinical assessment. Do not wait for pain before acting.

For moles and pigmented spots, the ABCDE guide is a useful prompt. Look for asymmetry, where one half differs from the other; an irregular border; uneven or multiple colours; a growing diameter; and evolution, meaning any change in size, shape, colour, sensation or behaviour. Evolution is particularly important. A mole does not need to match every ABCDE feature to need checking.

Not every concerning skin cancer is dark or mole-shaped. Arrange a skin check for a sore, scab or ulcer that does not heal; a pearly, pink or shiny lump; a red, rough or crusted patch; a spot that repeatedly bleeds; or a lesion that becomes tender, itchy or painful. A spot that looks different from the others on your skin is sometimes called an “ugly duckling” sign. Trust that observation.

Check areas that are easy to miss, including the scalp, ears, back, between the toes, soles of the feet and under the nails. Ask a partner, friend or clinician to help with hard-to-see areas. Skin cancer can also occur on the lips, particularly the lower lip, and smokers should be alert to persistent lip changes as well as changes inside the mouth.

Who should be especially vigilant?

Anyone can develop skin cancer. Fair skin, freckles, light-coloured eyes and a tendency to burn increase risk, but they are not the whole story. People with skin of colour can develop skin cancer too, and it may be diagnosed later when warning signs are overlooked. Darker skin does not eliminate the need to check new, changing or non-healing lesions.

Your risk may be higher if you have had skin cancer before, have a close family history of melanoma, have many moles, experienced severe sunburns, use or have used solariums, or take medicines that suppress the immune system. Age matters because UV damage accumulates, but melanoma also affects younger adults.

Outdoor workers deserve particular attention. Builders, farmers, tradies, delivery workers, gardeners, lifeguards and anyone who spends long periods outside can receive high UV exposure even on cool or cloudy days. In Victoria, New South Wales and Western Australia, UV can be strong for much of the year. Temperature is not a reliable guide. If the UV Index is 3 or above, use sun protection.

When to book a skin check

Book promptly if you have noticed a suspicious or changing lesion. A GP, dermatologist or qualified skin-cancer clinician can examine the area using appropriate tools and decide whether monitoring, photography, biopsy, removal or specialist referral is needed. A skin check is not a diagnosis by itself, but it is the right first step when something does not look right.

There is no single screening schedule that suits every Australian. People at higher risk may be advised to have regular full-body examinations, often yearly or more frequently depending on their history. Others may not need routine checks at fixed intervals, but should remain alert to changes and seek assessment without delay.

If a spot is rapidly changing, bleeding, painful, ulcerated or looks markedly different from your other spots, do not put it off until your next routine appointment. Every minute counts when a concerning lesion needs investigation. If you are unsure where to start, Skin Cancer Australia’s clinic resources can help you identify skin-check options in your state.

Prevention is practical, not perfect

No sun-protection routine removes all risk, and prevention cannot reverse previous UV damage. It can, however, reduce further exposure and lower your chance of future skin cancers. The aim is consistent protection, not waiting for a holiday or a heatwave.

Use a combination of protective measures whenever UV levels are 3 or higher. Slip on covering clothing, slop on broad-spectrum SPF50+ sunscreen, slap on a broad-brimmed hat, seek shade and slide on sunglasses. Reapply sunscreen according to the product directions, particularly after swimming, sweating or towel drying. Sunscreen is valuable, but it works best alongside clothing and shade rather than as a reason to spend longer in direct sun.

Plan outdoor activity around lower-UV times where possible. For workers, this may mean shade structures, protective uniforms, breaks out of direct sun and sun-protection supplies that are easy to access. Employers have a role in protecting workers from UV exposure, just as they do with other workplace hazards.

Parents and carers can make protection routine for children without making the outdoors feel off-limits. Hats by the door, sunscreen before school and shade at sport are small habits with long-term value. Avoid deliberate tanning and never use a solarium. A tan is evidence of skin damage, not a sign of health.

What happens after a suspicious spot is found?

A clinician may examine your skin with a dermatoscope, a handheld device that helps reveal structures not visible to the naked eye. They may photograph a lesion for comparison, remove it, or take a small tissue sample called a biopsy. The tissue is then examined in a laboratory to confirm whether cancer is present and, if so, what type.

Treatment depends on the diagnosis, size, location and stage of the cancer. Surgery is common and may be all that is required for an early lesion. Some non-melanoma skin cancers can be treated with creams, freezing, curettage, radiation therapy or other approaches. Melanoma treatment may involve wider surgery and, for more advanced disease, specialist treatments such as immunotherapy or targeted therapy.

This is why self-diagnosis is not enough. Benign lesions can resemble cancer, and cancers can resemble ordinary pimples, eczema or age spots. A qualified clinical examination provides clarity and a safe treatment plan.

A skin check is not about being alarmist. It is a practical decision when you notice a change, carry known risk factors or have spent years under Australia’s intense sun. Take a clear photo of a spot today if it helps you track it, then make the appointment rather than watching and waiting. Your future self may be grateful you acted early.
