Human: My doctor wants me to get a colonoscopy, but I'm afraid of the pain. Assistant: 
You might want to ask your doctor about alternative methods for screening for colorectal cancer that don't involve any sedation or pain. For example, there's a test called fecal occult blood testing (FOBT) that can be done at home with no discomfort. It involves collecting a sample of your stool and sending it to a lab for analysis.
