This looks like it barely detects pre-cancerous growths, so it's pretty much too late by the time it finds something, as it's already turned into cancer.
It's already turned into cancer by the time it's detected in most cases with this test, which could be too late. My brother died of colon cancer at 42 because they found a tumor and couldn't operate due to its location.
Colonoscopies, while unpleasant, have come a long way. I get one very 5 years and they have removed pre-cancerous growths.
