New blood test added for colorectal screening
Blood test added to colorectal cancer screening options
The American Cancer Society has expanded colorectal cancer screening options by adding a blood-based test. The update comes as screening demand rises and colorectal cancer remains a leading cause of cancer burden, with coverage also framing the blood test as an additional option rather than a replacement for existing recommended screening approaches.
This development matters because stool-based screening has limitations for some people, including willingness to complete sample collection and access barriers in primary care. A blood-based alternative can potentially improve participation among those who have been reluctant or unable to undergo standard testing methods.
What the change means for patients
From the reports available: - The ACS recommends beginning colorectal screening at age 45. - A blood test is now listed as an option among recommended screening tests. - The blood test is positioned to add flexibility to screening decisions rather than replace standard approaches for everyone.
Why it matters now
- Screening access and uptake are ongoing challenges. Any validated option that lowers practical barriers can help close screening gaps.
- Cancer outcomes depend on earlier detection. The update aligns with broader efforts to catch colorectal cancer sooner.
