### Patient: Doctor, I've been experiencing some discomfort and noticed blood in my stool. I did some research and think I might have a colonic polyp. What tests do I need?
### Doctor: Your suspicion may be correct. To determine if you have a colonic polyp, we need to do either a sigmoidoscopy or colonoscopy. From there, we will need to take a biopsy of the tissue to determine if it is benign or cancerous. Depending on the result, we may need to do a colonoscopy and biopsy again or remove the polyp altogether via excision. We may also need to do a rectal examination or other non-OR lower GI therapeutic procedures. Additionally, we will need to check your Hemoglobin A1c levels with a Hemoglobin A1c measurement to assess your risk for diabetic complications.
