Numerous CRC screening tests are available, with some that detect both adenomatous polyps and cancer and others that primarily detect cancer. SDNA testing has a high sensitivity for cancer but does not detect adenomatous polyps, according to Huffman and colleagues. Tests that detect both adenomatous polyps and cancer include flexible sigmoidoscopy, double-contrast barium enema, and computed tomography colonography. In addition to sDNA testing, FOBT and FIT have a high sensitivity for cancer.
