DefinitionActinic keratosis (AK) is abnormal growth of the skin. It results in a rough, scaly, or crusted patch of skin. AK tends to occur on sun-damaged skin. AK is not cancer but it can sometimes change to squamous cell skin cancer. Treatment includes removing lesions and monitoring for skin cancer.
