Although actinic keratosis is not a type of skin cancer, it can be a precursor. The rough, scaly patch of skin develops from years of sun exposure and is usually found in areas that see the most sun, like the scalp, neck, forearms, lips, ears, and face. Actinic keratosis grows slowly and does not usually have any other signs or symptoms, but a small percentage of them do become a squamous cell carcinoma over time.
