Actinic Keratosis on the Face and Scalp
Actinic keratosis (AK), also known as solar keratosis, is a common precancerous condition caused by prolonged exposure to ultraviolet (UV) rays. This skin condition predominantly affects areas such as the face and scalp, which are frequently exposed to sunlight. Left untreated, actinic keratosis can progress to squamous cell carcinoma, making early diagnosis and treatment essential.
