Exams and Tests
Your doctor can diagnose most seborrheic keratoses by doing a visual exam. He or she will look for the common appearance of a rough and bumpy surface.2 However, you may need a skin biopsy to rule out cancer if you have growths that:
- Itch or bleed.
- Become inflamed and red.
- Are dark brown to black.
