Diagnosing age spots may include:
- Visual inspection. Your doctor can usually diagnose age spots by looking at your skin.
- Skin biopsy. Your doctor may do other tests, such as a skin biopsy, to help distinguish an age spot from other conditions, such as lentigo maligna, a type of skin cancer.
During a skin biopsy, your doctor takes a small sample of your skin (biopsy) for microscopic analysis. A skin biopsy is usually done in a doctor’s office, using a local anesthetic.
