Cancer DNA is detectable in blood years before diagnosis

The big secret is that they could detect cancer very early in most people, but the health care companies don't want to pay for the screening. You can pay out of pocket for these procedures. I was told this by a cancer researcher

EDIT:

Adding these caveats:

1. There is a ton of nuance in the diagnosis, since most people have a small amount of cancer in their blood at all times

2. The screenings are 5-10k + follow up appointments to actually see if its real cancer

3. All in cost then could be much higher per person

4. These tests arent something that are currently produced to be used at mass scale

Probably not true. It’s much cheaper to catch cancer early than to treat advanced cancer later

Yeah but then you'd go through life having biopsies all the time. If all people did a full body MRI almost everyone would have weird lumps that doctors would have to biopsy to be really sure, and then what do you do? Do you biopsy yourself every time some weird tissue appears? Most of those will be nothing and you'll be going through the complications of surgeries and anesthesia all the time just to always make sure.
