A melanoma diagnosis in a parent, sibling or child can change the way you should approach skin checks. Family history melanoma screening advice is not about living in fear of every freckle. It is about recognising that your risk may be higher, knowing what changes deserve prompt attention, and having a screening plan that reflects your personal circumstances.

Australia has one of the world’s highest rates of skin cancer. High UV exposure, outdoor work and recreation, fair skin, a large number of moles, and past sunburns can all add to risk. When melanoma also runs in your family, delaying a professional skin check is not a sensible gamble. Early assessment can save your life.

Why family history changes melanoma risk

A family history does not mean you will develop melanoma. It does mean you should tell your GP or skin cancer clinician about it, especially if a first-degree relative – a parent, sibling or child – has had melanoma.

Risk can be higher when more than one close relative has been diagnosed, when melanoma occurred at a younger age, or when the same relative has developed multiple melanomas. Some families carry inherited gene changes associated with melanoma risk, although most melanoma is not caused by a known inherited condition.

Your clinician will consider family history alongside the rest of your risk profile. This includes your skin type, eye and hair colour, number and pattern of moles, history of severe sunburn, use of solariums in the past, immune-suppressing medicines, and how much UV exposure you receive through work or leisure.

The practical message is clear: family history should move skin surveillance higher on your health priority list. It should not be treated as background information to mention only if you happen to remember it during an appointment.

Family history melanoma screening advice: when to book

If you have a first-degree relative with melanoma, arrange a baseline full-body skin check with a qualified clinician if you have not already had one. A baseline examination gives the clinician a record of your skin and an opportunity to identify moles or spots that need closer monitoring.

How often you should return depends on your individual risk. Some people may be advised to have regular annual checks. People with very high risk, such as those with multiple affected relatives, many unusual moles, a personal history of melanoma, or a known inherited risk, may need more frequent review. Your clinician may use dermoscopy, total-body photography or sequential digital monitoring to watch particular lesions over time.

There is no one screening interval that suits every Australian. A yearly check may be appropriate for one person and insufficient or unnecessary for another. What should never wait for your next routine appointment is a new, changing, bleeding or otherwise suspicious spot.

Book an urgent assessment if you notice a mole or lesion that:

  • is growing, changing shape or developing uneven borders
  • has more than one colour, becomes very dark, or looks noticeably different from your other spots
  • bleeds, crusts, itches, hurts or does not heal
  • appears as a new changing lesion in adulthood
  • stands out as an “ugly duckling” compared with your usual moles.

Melanoma can occur on skin that is rarely exposed to the sun, including the soles of the feet, under nails, between toes, on the scalp and in genital areas. It can also occur in people with darker skin. Do not let assumptions about skin tone or body site delay assessment.

Know your family history before your appointment

Useful information can make a skin check more accurate and help your clinician decide whether you need closer surveillance. If possible, ask relatives what type of skin cancer they had and roughly how old they were at diagnosis. Melanoma is different from common keratinocyte skin cancers such as basal cell carcinoma and squamous cell carcinoma, so the distinction matters.

You do not need a perfect family medical record before seeking care. Even saying, “My mum had melanoma in her forties,” is clinically useful. Let the clinician know if several relatives on the same side of the family have had melanoma, pancreatic cancer or multiple unusual moles, as this pattern may warrant further discussion or referral.

If you have been treated for melanoma yourself, tell your close family members. They do not need to panic, but they should understand the value of regular self-checks, sun protection and a professional baseline skin examination.

Professional checks and self-checks work together

A professional skin check is more than a quick glance at one mole. A trained clinician can examine difficult-to-see areas, use a dermatoscope to inspect pigment patterns below the skin’s surface, compare lesions, and decide whether monitoring, biopsy or referral is needed.

Self-checks still matter between appointments. Set aside time once a month in a well-lit room. Use a full-length mirror and a hand mirror, or ask a partner, family member or trusted friend to look at areas you cannot easily see, particularly your scalp, back, buttocks and the backs of your legs.

Look over your face, ears, neck, chest, abdomen, arms, hands, nails, legs, feet and soles. Take note of existing moles so you can recognise change. Photographs can be helpful for your own comparison, but they are not a substitute for clinical imaging or medical assessment.

The ABCDE guide can help you notice concerning changes: asymmetry, border irregularity, colour variation, diameter or a lesion that is different from others, and evolving size, shape, colour or symptoms. Yet melanoma does not always follow a checklist. A small spot can be serious, and some melanomas are pink, red or skin-coloured rather than brown or black. If something feels wrong, get it checked.

Reduce UV exposure without relying on screening alone

Screening finds suspicious changes early. It does not prevent melanoma from developing. If family history places you at higher risk, daily sun protection is part of your care plan, not an optional extra for beach days.

Check the UV Index and use sun protection whenever it is 3 or above. Choose shade where possible, wear sun-protective clothing, a broad-brimmed hat and UV-rated sunglasses, and apply broad-spectrum, water-resistant SPF 50+ sunscreen generously. Reapply at least every two hours when outdoors, and sooner after swimming, sweating or towel drying.

For outdoor workers, this may mean changing routines rather than simply applying more sunscreen. Seek shade for breaks, wear protective workwear, and avoid relying on a cap alone to protect your ears, neck and face. For parents with a family history, these habits also give children a practical model for lifelong sun safety.

Avoid deliberate tanning and never use solariums. A tan is a sign that UV radiation has damaged the skin, not evidence that it has become protected.

What happens if a clinician finds a suspicious lesion?

Most spots assessed at a skin check will not be melanoma. If a lesion looks concerning, the clinician may recommend a biopsy or complete excision so it can be examined in a laboratory. This is the only way to diagnose melanoma with certainty.

Waiting to see whether a suspicious spot settles is rarely the right approach when melanoma is a possibility. Melanoma can spread beyond the skin, but when detected early it is often treated successfully with surgery. Every minute counts when a changing lesion needs assessment.

Family history can feel confronting, particularly if someone close to you has been through melanoma treatment. Turn that concern into a clear next step: record what you know, check your skin, protect it from UV, and book a professional skin check suited to your risk. Knowledge can save your life.
