Where Melanoma Hides: The Spots You're Not Checking
Scalp, soles, nails, between the toes: the zones that are easy to miss.
Invasive melanoma diagnoses rose ~46.6% over the decade 2016-2026 (Skin Cancer Foundation).
Five or more sunburns roughly doubles a person's lifetime risk of melanoma.
Frequently asked questions
Can sunscreen prevent skin cancer?
Evidence indicates yes. In the landmark Australian Nambour trial, adults using sunscreen daily had fewer melanomas — with a statistically significant reduction in invasive melanoma — than those using it at their discretion. Regular broad-spectrum use, alongside shade and clothing, lowers skin-cancer risk.
What are the early warning signs of melanoma?
Watch for the ABCDEs: Asymmetry, irregular Borders, uneven Color, Diameter over about 6 mm, and Evolving (changing) spots. Also note any 'ugly duckling' mole that looks different from your others, or a sore that won't heal. See a dermatologist promptly about anything new or changing.
How often should I get a skin check?
Examine your own skin about monthly, and see a dermatologist for a professional check at least yearly — more often if you have many moles, fair skin, a history of sunburns or skin cancer, or a family history. Early detection makes melanoma highly treatable.
