Understanding Mole Checks and Skin Cancer Risk
By Content Writer, Dunman Medical Clinic
Skin cancer risk is often associated with temperate countries with strong seasonal sun exposure, but year-round tropical UV intensity carries its own risk profile that's worth taking seriously, regardless of skin tone. A simple, regular self-check habit is one of the most effective tools available, and it costs nothing but a few minutes.
The standard framework for assessing a mole is the ABCDE rule: Asymmetry, Border irregularity, Colour variation, Diameter greater than about 6mm, and Evolution — meaning any change over time. No single feature is diagnostic on its own, but a mole that's changed in more than one of these ways is worth having examined rather than monitored indefinitely at home.
Skin tone affects risk level but doesn't eliminate it — melanoma and other skin cancers occur across all skin tones, sometimes in less sun-exposed areas like the soles of the feet or under nails, which are easy to overlook in a casual self-check. This is part of why a periodic proper skin check, not just a glance in the mirror, is worth building into a routine.
Practical tips
Use the ABCDE framework for a structured self-check
Asymmetry, Border irregularity, Colour variation, Diameter over 6mm, and Evolution (change over time) — a mole showing more than one of these warrants a proper look.
Don't skip less sun-exposed areas
Soles, palms, and under nails are less common sites but are genuinely checked in a thorough skin exam — don't assume risk is limited to sun-exposed skin.
Photograph moles you're tracking
A dated photo series is far more reliable than memory for noticing gradual change over months.
Daily sun protection is still the best prevention
Even with a tan or naturally deeper skin tone, daily sunscreen meaningfully reduces cumulative UV damage in a tropical climate.
When to see a doctor
Get any mole checked that's changed in size, shape, colour, or texture, started bleeding or itching, or simply looks different from your other moles — earlier assessment is always lower-risk than a wait-and-see approach.
