Is Shield a Good Colorectal Cancer Screening Blood Test? Hear From an MSK Expert (Memorial Sloan Kettering Cancer Center)

Dr. Robin Mendelsohn, Co-Director of MSK’s Center for Young Onset Colorectal and GI Cancers, weighs in on the FDA-approved Shield blood test — the first of its kind for average-risk adults 45 and older. While it’s less invasive than colonoscopy, she notes that Shield misses over a third of stage 1 colorectal cancers and detects just 13% of precancerous polyps, falling short of the prevention goal.
