A skin check is not something to put off until a mole looks dramatic. Most skin cancers are more treatable when found early, and many concerning changes are subtle at first. So, how often should adults get skin checks? The right interval depends on your personal risk, but any new, changing, bleeding or non-healing spot needs prompt clinical assessment – regardless of when your last check was.
Australia has one of the highest rates of skin cancer in the world. High UV levels, outdoor work and recreation, and years of accumulated sun exposure all matter. A regular skin-check routine gives you a better chance of noticing a problem before it becomes more serious.
There is no one skin-check schedule for every adult
For adults at average risk, a full professional skin check is often considered every 12 months, particularly from midlife onwards or after years of significant sun exposure. However, Australia does not have a single population-wide screening timetable that applies to everyone. Your GP, skin cancer doctor or dermatologist can recommend an interval based on your skin, medical history and level of risk.
Some people need checks more often than yearly. Others may be advised to attend every one or two years while also monitoring their own skin between appointments. The key point is this: a routine appointment is preventive care, but a suspicious lesion is a reason to book now.
A clinician may use dermoscopy – a magnified lighted device – to examine spots that are difficult to assess with the naked eye. If you have many moles or a history of melanoma, they may also recommend baseline photographs or digital monitoring to identify small changes over time.
Who should have skin checks every 3 to 6 months?
More frequent checks are commonly recommended for people with a high risk of melanoma or other skin cancers. The precise schedule should be set by the clinician managing your care, as it can change after a diagnosis or biopsy result.
You may be in a higher-risk group if you have had melanoma, squamous cell carcinoma, basal cell carcinoma or multiple precancerous sun spots before. A close family history of melanoma, especially in a parent, sibling or child, also deserves discussion with your doctor.
Other factors that can justify closer surveillance include having many moles, unusual-looking moles, fair skin that burns easily, red or blond hair, blue or green eyes, or a history of intense sun exposure and blistering sunburns. This includes people who have worked outdoors in construction, farming, transport, landscaping, fishing or sport.
People taking medicines that suppress the immune system, including some transplant recipients and people receiving particular treatments for autoimmune conditions or cancer, can develop skin cancers more often and sometimes more aggressively. They should ask their treating team or dermatologist how often to attend.
High risk is not limited to people with fair skin. Skin cancer can occur in people with skin of colour, and delayed diagnosis is a real concern when a change is dismissed because it does not fit the usual picture. Check the whole body, including the palms, soles, nails, lips and areas that receive little sun.
When should adults get a skin check sooner?
Do not wait for your next routine check if a spot is new, changing or simply does not feel right. Melanoma can develop from an existing mole or appear as a new mark. Non-melanoma skin cancers may look like a persistent scaly patch, a sore that will not heal, or a pearly or crusted bump.
Use the ABCDE guide as a prompt for assessment. Look for asymmetry, an irregular border, uneven colour, a diameter that is growing, and evolution or change. But do not rely on this list alone. Some melanomas are small, pale, pink, raised or lack obvious pigment.
Book an appointment promptly if you notice any of the following:
- a mole or spot that changes in size, shape, colour or sensation
- bleeding, crusting, itching or pain without a clear explanation
- a sore, scab or pimple-like lesion that does not heal within a few weeks
- a dark streak or changing mark under a fingernail or toenail
- a new lesion that looks different from the other spots on your skin – the “ugly duckling” sign
For smokers and people with substantial sun exposure, persistent changes to the lips also need attention. A pale, scaly, thickened or ulcerated area on the lower lip should be assessed rather than treated as ordinary dryness.
Check your own skin between appointments
Professional examinations and self-checks work together. A clinician brings trained assessment and diagnostic tools; you bring familiarity with your own skin. Aim to look over your skin regularly, such as every three months, and sooner if you have noticed a new spot.
Use a well-lit room, a full-length mirror and a hand mirror. Check your face, ears, scalp, neck, chest, back, arms, hands, buttocks, legs and feet. Look between the toes, under the breasts, in skin folds, on the soles, and around the genital area. Ask a partner, family member or friend to check hard-to-see places such as your scalp and back if possible.
Photographs can help you notice change, particularly if you have many moles, but they are not a substitute for a clinical assessment. Lighting, angles and image quality can be misleading. If a photograph worries you, arrange a skin check rather than trying to compare it for months.
What happens at a professional skin check?
A proper skin check usually begins with questions about your history: previous skin cancers, family history, medications, work, sun exposure and any spots you have noticed. Tell the clinician about every lesion that concerns you, even if it seems minor.
You may be asked to undress to your underwear or gown so the clinician can examine areas you cannot easily inspect yourself. This can feel exposing, but a thorough check matters because skin cancers can occur on the scalp, back, legs, soles and other covered sites. You can ask for a chaperone, request a clinician of a particular gender where available, or raise any concerns before the examination begins.
If a spot needs closer assessment, the clinician may photograph it, monitor it over a short period, take a biopsy or arrange referral to a dermatologist. Not every suspicious-looking mark is cancer, and not every biopsy leads to major treatment. The purpose is to get a clear diagnosis without delay.
Your risk can change over time
The interval that suited you five years ago may not suit you now. Ageing, a new skin cancer diagnosis, immune-suppressing medication, or decades of outdoor work can alter your risk. A history of tanning bed use is also relevant, even if it was years ago.
Make skin checks part of your broader sun-health plan. Seek shade when UV levels are high, wear protective clothing and a broad-brimmed hat, use sunglasses, and apply broad-spectrum SPF50+ sunscreen correctly. These measures reduce future UV damage, but they do not remove the need to assess skin that has already been exposed.
If you are unsure when to book, choose caution. A timely skin check can provide reassurance, identify precancerous changes, or detect a cancer while treatment is simpler. Every minute counts when a suspicious spot is changing – make the appointment that gives you a clear answer.
