Stool-based tests, blood-based tests, and colonoscopy are key modalities for colorectal cancer screening, each with distinct methodologies and benefits. Stool-based tests, including fecal immunochemical tests (FIT) and guaiac-based fecal occult blood tests (gFOBT), detect hidden blood in stool samples, indicating potential malignancies. Blood-based tests, though less common, identify circulating tumor DNA or specific biomarkers in the bloodstream. Colonoscopy, the gold standard, involves direct visualization and potential removal of polyps or lesions in the colon and rectum, offering both diagnostic and therapeutic advantages.
