The American Cancer Society has updated its guidelines to recommend blood tests as an alternative screening method for colorectal cancer in adults 45 or older who cannot or will not undergo colonoscopies, which remain the gold standard; these blood tests, along with home-collected stool tests that detect molecular markers, can dramatically improve survival rates when cancer is diagnosed before symptoms appear, as early treatment is more effective than treatment at advanced stages when cancer may have spread to other body parts.

Blood Tests Now Recommended for Colon Cancer ScreeningAdded:
With colorectal cancer on the rise in younger adults, there is now new options to test for it besides colonoscopies.
The American Cancer Society released an updated guideline yesterday recommending blood tests to screen for colorectal cancer in adults 45 or older who are unable or unwilling to get a colonoscopy. Colonoscopies are still considered the gold standard. The new guideline also recommends additional stool tests which are collected at home and sent to a lab. The tests can detect molecular markers associated with colorectal cancer. Screening can dramatically improve survival if a cancer is diagnosed before symptoms begin because treatment can start early.
When cancer is found at a more advanced stage, it may have spread into other parts of the body.
