Stool-based tests, such as FIT and gFOBT, detect occult blood in stool, serving as non-invasive screening options for colorectal cancer.
Blood-based tests focus on identifying circulating tumor DNA or specific biomarkers, offering a less invasive alternative to traditional screening methods.
Colonoscopy provides direct visualization of the colon and rectum, allowing for both detection and removal of polyps, making it the gold standard for colorectal cancer screening.
