Screening for Colorectal Cancer

What is a colon cancer screening?

There are several screening methods which have different abilities to detect or prevent CRC: stool blood test known as Fecal Occult Blood Test (FOBT) or Fecal Immunochemical Test (FIT), flexible sigmoidoscopy, colonoscopy, CT colonography, barium enema with air contrast, and stool DNA testing. Tests which mainly detect cancer include FOBT, FIT, and stool DNA. Tests which mainly detect polyps or cancer include colonoscopy, flexible sigmoidoscopy, CT colonography, barium enema, and colon capsule endoscopy. Colonoscopy is considered the gold standard of colorectal cancer screening methods for its ability to view the entire colon and both detect and remove polyps during the same procedure.

What are the colon cancer screen recommendations?

Beginning at age 50, both men and women at average risk for developing CRC should have a colonoscopy every 10 years. The risk of developing CRC increases with age, with more than 90 percent of cases occurring in persons aged 50 or older.

Men and women should begin screening earlier and more often if they have any of the following CRC risk factors: a family history of CRC or polyps, a known family history of inherited CRC syndromes, a personal history of CRC, or a personal history of chronic inflammatory bowel disease (ulcerative colitis or Crohn's Disease).

People with risk factors for CRC or family history of CRC should talk with our gastroenterologists about screening at an earlier age and find out how often they need to be screened.
