How many have had a colonoscopy without anesthesia?

I didn't have anesthesia when I had my colonoscopy, because I'm a control freak and don't like being knocked out, and I didn't even have anesthesia when I did an endoscopy a week later and so I got to watch it all on the monitor. I watched as the doctor found the first and second polyps and removed them. I was feeling pretty good about things as he turned the corner into the ascending section of the colon and there I got to see in real-time this huge, grayish, greenish, reddish tumor. I said something like: "That isn't good is it?" Without missing a beat he launched into something like an angry attack. He told me, shaking his head in disgust, things would have been different if I had listened to him over a year ago. He told me how it had to come out, and that it had all the signs of cancer, and that they had to rush me into a CT scan to see if the cancer had spread and repeated several more times that I should have had the colonoscopy a year ago when he had recommended it because it wouldn't have been so advanced. On and on he went, as if I was the dumbest person on earth for not having taken his advice over a year ago. I felt like taking that probe that was still up my butt and shoving it up his. Anyway, they operated a month later. I asked the surgeon if they could do it without anesthesia, and he just looked at me bewildered. It turned out that the tumor was the size of an orange, and had nearly punched through the wall and I was staged 2A. That was over three years ago. I've had many CT scans since then and several colonoscopies, all without anesthesia, and I'm clear of cancer, and hope to stay that way. At 71-years old I'm still in the game, still working as a freelance writer, still creating havoc everywhere a go (I'm one of those type A personalities and that's what we do) but I'm having a great time and I feel very lucky that I'm still on the planet.
