Actinic Keratoses
An actinic keratosis (AK), also known as a solar keratosis, is a crusty, scaly growth caused by damage from exposure to ultraviolet (UV) radiation. You'll often see the plural, “keratoses,” because there is seldom just one. Though the vast majority of actinic keratoses remain benign, they reveal that you have sustained sun damage and could develop any kind of skin cancer, especially the second most common form of the disease, squamous cell carcinoma (SCC). If you have one AK, you may develop others. The more AKs that remain untreated, and the older these lesions are, the greater the chance that one or more may become an SCC. AKs can be treated by
