This. Cologuard is also not terribly helpful in catching precancerous polyps and there's a concern about false sense of security with it. You want to catch these things before they actually get cancerous.


As my neighbor was dying of colon cancer he told me never to trust the poop test.


Cologuard is actually great for the people who can’t be convinced to do a colonoscopy. I had a family member who was one of those people, had them before and decided she was done, not worth it to her. Her doctor convinced her to at least do Cologuard. The Cologuard did pop positive, and she did have numerous precancerous polyps, and now she goes for regular colonoscopies.

It's more like 8% v 5% for colonoscopy, and it's lower for younger adults (45-49).

There is apparently Cologuard Plus which has fewer false negatives and some other advantages.

Given that it is so easy to do, I think it makes a lot of sense.


My Dr also said useless.

Having now known several people who died of pancreatic cancer that was not diagnosed until it had spread to other organs, I would be willing to pay $600/yr for them to run a blood test even if it only catches half of these cancers. The clinical data indicates that Galleri for instance will catch 83% of pancreatic cancers, and 83% of ovarian cancers (also typically asymptomatic). It looks like it doesn’t do so well on prostate, kidney, uterine or breast cancers, catching less than 30% of those.


The problem with pancreatic cancer is it does not matter when you catch it. It can go from stage 1 to 4 in a couple months and most people are not lucky enough to survive past a few years.

I’m planning to get Galleri when I turn 50. I get that for a population we don’t yet know if it makes sense but I’m an N of 1 and can afford it.

I heard that some insurance, including for the military, will start covering the Galleri test this year.

If it’s called CancerGuard it should prevent cancer. Like ScotchGard.

I spent a long time comparing the CancerGuard with the (slightly more expensive) Galleri test, and chose the Galleri test. Neither are generally covered by insurance -- and follow-up scans might not be covered even if the blood tests are positive!
