Key conditions to know
The most searched skin conditions

Basal Cell Carcinoma
The most common cancer in humans. Slow-growing, rarely spreads, but can cause serious tissue damage if untreated.
Actinic Keratosis
Rough, sandpaper-like patches from years of sun damage. The most common precancer - 5-10% progress to squamous cell carcinoma.
Dysplastic Nevus
Atypical moles with irregular features. The single strongest visual risk marker for melanoma.
Seborrheic Keratosis
Waxy, stuck-on growths - the most common benign tumor in adults over 50. Harmless but frequently mistaken for melanoma.
