Actinic Keratoses (Pre-Cancer)
Actinic keratosis (AK) is a skin condition that appears as rough, scaly patches or spots on areas of skin that have been exposed to the sun for prolonged periods of time. It is considered a precancerous lesion, as it can sometimes develop into a type of skin cancer called squamous cell carcinoma. AKs are most commonly found on the face, ears, neck, hands, and arms. They are often treated with cryotherapy (freezing), topical chemotherapeutic creams, photodynamic (Blu-U) light therapy, or medium-depth chemical peels.
