It’s caused by ultraviolet (UV) damage to your skin. And, since some actinic keratoses can turn into squamous cell skin cancer, these lesions are often considered precancerous. The good news is they are not life-threatening, and if they are found and treated early, do not have the chance of developing into skin cancer.
Actinic keratosis develops slowly. It usually appears on the areas of your skin that are frequently exposed to the sun. In addition, if you have actinic keratosis it’s likely you will have more than one lesion. The lesions are commonly found on your face, ears, neck, backs of hands, forearms and balding scalp.
