Actinic keratosis (AK) is a precursor lesion to squamous cell carcinoma, a type of skin cancer. AKs are due to chronic sun exposure when the skin is damaged by ultraviolet rays over decades of time. They can present as individual lesions and also as large patches. The most common areas for AKs are the face, scalp, ears, forearms, hands, and shins. It is important to identify and treat AKs when they appear before they become skin cancers. Treatment for AKs vary from cryotherapy (freezing with liquid nitrogen), topical chemotherapy, curettage, and Photodynamic Therapy (PDT). Your treatment will be tailored to the severity of your AKs, the areas of involvement, your skin cancer history, skin type, and other variables.
