Overview, Causes, & Risk Factors
Actinic keratosis occurs most commonly in fair skin, especially in the elderly and in young individuals with light complexions. The growths occur in sun-exposed skin areas. The growths begin as flat scaly areas that later develop a hard wart-like surface.
They are classified as precancerous growths. If left untreated, approximately 10% of actinic keratoses develop into squamous cell carcinoma.
