  Anal Cancer: Diagnosis

  To determine if you might have anal cancer, you will need certain exams and tests to be sure. Diagnosing anal cancer starts with your healthcare provider asking you questions. You will be asked about your health history, your symptoms, risk factors, and family history of disease. He or she will also do a physical exam. This includes a digital rectal exam (DRE). During a DRE, your healthcare provider puts a gloved, lubricated finger into your rectum. He or she checks for hard or lumpy areas.
