They are relatively simple and accessible, making them a valuable initial screening tool. The presence of blood in stool does not necessarily mean cancer, but it warrants further investigation.
    • Fecal Immunochemical Tests (FITs): Similar to FOBTs, FITs also detect blood in stool, but they use a different method, which is often more sensitive to detecting small amounts of blood. Their increased sensitivity means that FITs can potentially detect early-stage cancers or precancerous polyps more effectively than FOBTs.
    • Colonoscopy: This procedure involves inserting a flexible tube with a camera into the colon to visualize the lining and identify any abnormalities, including polyps or cancerous growths. It is considered the gold standard for colorectal cancer screening, as it allows for both visualization and potential removal of precancerous polyps. While more invasive than other methods, colonoscopy offers a high degree of accuracy.

    • Sigmoidoscopy: A similar procedure to colonoscopy, but it only examines the lower part of the colon and rectum. It’s less invasive than a full colonoscopy and is often used as a screening tool for those who cannot undergo a full colonoscopy.
