The market taxonomy by type distinguishes six diagnostic modalities: fecal immunochemical test (FIT), guaiac‑based fecal occult blood test (FOBT), stool‑DNA assay, colonoscopy, computed tomography colonography (CTC), and flexible sigmoidoscopy. FIT dominates the non‑invasive segment, capturing roughly 45 % of total test sales due to its ease of collection, high sensitivity for distal lesions, and favorable reimbursement. FOBT, an older technology, retains about 15 % share, primarily in low‑resource settings where cost constraints limit adoption of FIT. Stool‑DNA, marketed as a high‑sensitivity option for both proximal and distal neoplasia, contributes near 10 % of revenue, reflecting its premium pricing and limited insurer coverage. Among invasive procedures, colonoscopy remains the gold standard, accounting for approximately 25 % of market value despite lower procedural frequency, because of its therapeutic capability and comprehensive visualization. CTC and flexible sigmoidoscopy together occupy the remaining 5 %, serving niche clinical pathways where radiation‑free imaging or limited colonic assessment is preferred. This type‑based segmentation clarifies the relative scale of each technology and guides investment decisions across the colorectal cancer screening ecosystem.
