I mostly agree. I had a CT scan of 1/3 of my body for a specific issue, but as a consequence I got very high confidence that I was cancer-free in that portion of my body. It is such a good feeling that part of me wants to pay out-of-pocket to get the rest checked.
I think though that this test has massive value in earlier detection, cost, and remote lab work.
Dude, CTs can be risky. They use ionizing radiation, which increases your risk of cancer. It's really only an issue with repeated use, but I think there's a study out there claiming 50k early deaths each year can be attributed to repeated use of CTs. I don't have any medical background, but personally I would prefer imaging that does not use ionizing radiation when possible, just to save up some "credits" for when I may need to use the other type (like CT for possible stroke).
