My doctor wants me to get a colonoscopy, but I'm afraid of the pain.

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.
