Shield Blood Test vs Colonoscopy: The Catch No One Explains

Added: 2026-06-02

[00:00:00]There's a blood test for colon cancer screening.

[00:00:02]Sounds amazing, but there's an important catch. The Shield blood test can detect if you already have colon [music] cancer, but it misses nine out of 10 polyps that can turn into cancer. The best colon cancer [music] screening tests don't just find cancer, they help stop it before it starts. Detecting something late and preventing it early are not the same thing. That's like having a smoke detector that goes off after the house is already on fire. But if you won't get a colonoscopy or in a box, sure, do the blood test because some screening is better than no screening. [music] Just know what you're trading off.
