Actinic keratosis

Summary of Actinic keratosis
Actinic keratosis is a pre-cancerous patch of thick, scaly, or crusty skin. These growths are more common in fair-skinned people and those who are frequently in the sun. They usually form when skin gets damaged by ultraviolet radiation. Actinic keratosis is considered potentially pre-cancerous. Untreated lesions have up to a 20% risk of progression to squamous cell carcinoma, so treatment by a dermatologist is recommended.
