- The American Cancer Society now includes an FDA‑approved blood test (Guardant Shield) as an alternative for people who find colonoscopy or stool tests too burdensome — it detects tumor DNA in the blood.
- Colonoscopy remains the gold standard; stool tests like Cologuard and Colosense are better at finding early or precancerous lesions, while the blood test is more accurate for advanced cancers and is recommended only if other tests are declined.
- Screening is recommended from age 45 to 75, and about one‑third of eligible Americans remain unscreened — adding a blood option may help reach people who otherwise skip screening.
