Colonoscopy has a big advantage in that they are already in there. If they see anything forming that is pre-cancerous they can take it out before it turns into a problem that would show up on a Cologuard test.

But that’s also highly dependent on how good the doctor is at finding the problems. Apparently doctors in the US find precancerous polyps 40% of the time according to the article. That may not be so great given the time between screenings (ten years) if one is missed.

And the big disadvantage that to get there your need to book 2 professionals (?) and take pretty much one day off, and there are risks associated with anesthesia and the procedure itself I don't think it scales (Not to mention the interests of doctors of suggesting things that make them more money) Edit: now I see TFA mentions risk of perforation and that the risk is smaller without anesthesia

  Well, in the US, they're following normal protocol. It would probably be irresponsible for them to try to dissuade you from a colonoscopy. But, yes, it's a day involving a gastroenterologist, typically an anesthesiologist, nurses presumably, and someone to take to back and forth from the procedure. It's definitely not standard lab work.

  In Japan, everyone over 40 gets yearly colonoscopies as part of a general health check up. That should be a really good source of data, someone should take a look at that. But what I was getting at is that it can scale.

    Source? Yearly colonoscopies sound dubious - my google search results said they use fecal occult blood tests yearly with a follow-up colonoscopy if you test positive which sounds more reasonable to me.

      The source is that I live here and everyone talks about it. Poop tests are for everyone over 30

    Yearly? That's crazy. I had yearly colos AFTER I had rectal cancer, but now I'm on the 10 year plan. I can't see yearly being both cost-effective and safe.

  You also need to find someone to transport you to/from the procedure. I moved to a new city and didn't know anyone. I was told to get a colonoscopy for no other reason than I was 50. There was literally no one I could ask to take off half a weekday to accompany me. Ended up doing the FIT test (stool sample) instead (and once/year thereafter) and 6 years on still haven't had a colonoscopy.
