Melanoma's Survival Story: Why Early Detection Is Everything
The survival gap between melanoma caught early and caught late is enormous.
About 9,500 people are diagnosed with skin cancer in the U.S. every day (AAD).
With about 1 in 5 Americans developing skin cancer in their lifetime (AAD), regular self-checks aren't paranoia—they're how you stay in the early-detection window.
Frequently asked questions
Does skin cancer affect darker skin tones?
Yes. People with darker skin get skin cancer less often but are frequently diagnosed later, when it's harder to treat — and melanoma can appear in less sun-exposed areas like the palms, soles and under the nails. Everyone, regardless of skin tone, should use sun protection and watch for changes.
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.
