Tests and diagnosis
By Mayo Clinic staffYour doctor can usually diagnose actinic keratoses by inspecting the skin. 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 (biopsy) for analysis in a lab. A biopsy can usually be done in a doctor's office using a local anesthetic.
