Your doctor can usually diagnose actinic keratosis simply by looking at it. If there's any doubt, your doctor may do other tests, such as a skin biopsy. During a skin biopsy, your doctor takes a small sample of your skin for analysis in a lab. A biopsy can usually be done in a doctor's office after a numbing injection.
