Skin checks: how often, and what to look for
Australia has one of the highest rates of skin cancer in the world. Caught early, most skin cancers are very treatable. Knowing what to look for, and when to book, is one of the simplest things you can do for your health.
Why skin checks matter in Australia
With our sunny climate and outdoor lifestyle, Australians have a very high lifetime risk of skin cancer. The good news is that skin cancers (including melanoma, the most serious type) are usually very treatable when found early. That's exactly why regular checks, both your own and your doctor's, are worth the small effort.
How often should you get a skin check?
There's no single rule: it depends on your personal risk. Many adults have a professional skin check about once a year. You may need them more often if you:
- have fair skin that burns easily, or lots of moles;
- have had a lot of sun exposure or sunburns, or used solariums in the past;
- have a personal or family history of skin cancer; or
- have noticed a spot that's changing.
In between professional checks, it's worth looking over your own skin every few months so you get to know what's normal for you.
What to look for: the ABCDE guide
A simple way to remember the warning signs of melanoma is ABCDE:
- A for Asymmetry: one half of the spot doesn't match the other.
- B for Border: edges that are irregular, ragged or blurred.
- C for Colour: more than one colour, or uneven colour.
- D for Diameter: larger than about 6mm (the size of a pencil eraser), though melanomas can be smaller.
- E for Evolving: any spot that is changing in size, shape or colour, or that itches or bleeds.
The single most important sign is change: a spot that's new, growing, or different from your others.
What happens at a skin check
A skin check is quick and usually very comfortable. Your doctor examines your skin from head to toe, using a dermatoscope (a special magnifier with a light) to look closely at anything of interest. If a spot needs a closer look, they might photograph it to monitor over time, or arrange a small biopsy, a minor procedure to remove a tiny sample for testing. Most spots turn out to be nothing to worry about.
When to book
Don't wait for your annual check if you notice a spot that is new, changing, bleeding, or simply doesn't look like your others. It's always better to have it checked and be reassured.
