Colon cancer screening is recommended for adults starting at the age of 45, depending on the individual’s risk factors, and can be done through a variety of screening tools. The most common tests for early prevention of colon cancer include fecal occult blood testing (FOBT), flexible sigmoidoscopy, double-contrast barium enema, and colonoscopy. FOBT is a noninvasive test conducted once a year that looks for hidden traces of blood in stool samples; it has been found to detect polyps or cancerous growths early on. Flexible sigmoidoscopy allows doctors to visually inspect the lower portion of the large intestine using an illuminated tube with a camera attached; this procedure should be done every five years. Double-Contrast Barium Enema is similar to flexible sigmoidoscopy but utilizes X-rays instead which are used to examine both the inside and outside of the large intestine; this procedure should also be done every five years. Finally, colonoscopies are more invasive procedures where doctors use long tubes with cameras attached to visualize the entire colon; these should be done every 10 years starting at age 50 or earlier depending on risk factors.
