What is new colorectal screening guidance?

New colorectal cancer screening guidance adds stool and blood tests

New screening guidance is expanding colorectal cancer screening options beyond colonoscopy alone. The update adds stool-based and blood-based testing approaches, aiming to improve uptake and detect cancers earlier.

The reporting indicates that the guidance includes:

• Stool tests as an alternative route to screening
• Blood tests as an additional option

This matters because colorectal cancer screening programs often struggle with attendance: stool and blood options can be easier to deliver than procedures that require bowel preparation and clinical scheduling. Earlier detection can reduce the likelihood that cancer is diagnosed only after it has advanced.

In parallel, separate coverage in the pool says the American Cancer Society also updated its recommendations to start screening at 45 and to include blood-based tests as an option. The emphasis across items is consistent: screening access is being broadened with less invasive tests.

For people considering screening, the takeaway is not that one test is universally best. Instead, guidelines are moving toward giving clinicians and patients more choices based on risk, feasibility, and local availability.

For health systems, adding noninvasive tests can help increase the proportion of eligible adults who get screened and reduce delays in diagnosis. For patients, it can mean starting screening earlier in life and potentially avoiding invasive testing if a simpler test suggests the risk is low.

If you’re determining what applies to you, clinicians typically consider age, family history, prior polyps, symptoms, and previous screening results when selecting between stool and blood options.
