Actinic keratosis: Overview
Also called solar keratosis
An AK forms when the skin is badly damaged by ultraviolet (UV) rays from the sun or indoor tanning. Most people get more than one AK. When you have more than one AK, you have actinic keratoses, or AKs.
Anyone who has many AKs should be under a dermatologist’s care. Most people who have many AKs continue to get new AKs for life. AKs are considered precancerous. Left untreated, AKs may turn into a type of skin cancer called squamous cell carcinoma.
By seeing a dermatologist for checkups, the AKs can be treated before they become skin cancer. If skin cancer does develop, it can be caught early when treatment often cures skin cancer.
