Colon and rectal cancer is often one of the most avoidable cancers. Your rectum and colon are the large intestine, which absorbs water and nutrients from digested food, and holds solid waste before it's discharged from the body

A screening for colon cancer is the process of checking for polyps and growths that could be cancerous on the inner wall of the rectum and colon with no gastrointestinal (GI) symptoms present. A polyp is a growth that is not cancerous in the colon. Some of these might grow into cancer later. Early detection and removal of polyps and malignant growths can help avoid issues and death at the hands of colorectal cancer.

Our board-certified gastroenterologists at Colorado Gastroenterology frequently perform colon cancer screenings for Denver, CO patients. To book a screening, contact our facility.

Denver, CO individuals should speak with their GI doctor at Colorado Gastroenterology about when to go to a screening and what tests are suggested. The following tests may be used for a colorectal cancer screening:

  • Flexible sigmoidoscopy: A sigmoidoscopy is used to look at the inside of the lower colon and rectum. A finger-sized tube with a camera attached is inserted through the rectum so we can get images of the inside wall and some of your colon. It might also be used for taking a biopsy of the tumor or polyp as well as extracting some polyps. However, a colonoscopy needs to be completed to see the whole colon and get rid of all tumors or polyps. This procedure is generally pretty safe but there is a minimal risk of a bowel tear, bleeding, and infection.


  • Colonoscopy: A colonoscope is similar to a sigmoidoscope, except it's longer and is used to examine the inside of the entire colon. The colonoscope is snaked through the rectum and your doctor can see the entire colon on our computer system. GI tools may be passed through the colonoscope to take a biopsy and extract polyps. Sedation will be needed. There is a small chance of the bowel tearing, bleeding, and infection due to the procedure.


  • Virtual colonoscopy: This is a CT scan of the colon. The person is asked to lie on our treatment table where our CT scanner will take images of your colon. This is a noninvasive treatment and doesn't call for sedation. If we find any abnormalities, a colonoscopy will have to be performed to remove the tumors or polyps.

    • Double-contrast barium enema: A thin tube is inserted the rectum and barium sulfate, a chalky white liquid, and air are pumped into your colon. The barium suspension will line the outer walls of the colon. X-ray images of the colon will then be taken to show any abnormalities on the inner wall of the colon. If any abnormalities are identified, a colonoscopy will be required to extract the polyps or tumors.

  • Fecal test: These are completed with a fecal sample and are very safe. Fecal tests may not give confirmatory results but might suggest abnormalities in the GI tract, necessitating further tests. A colonoscopy needs to be repeated if results are positive, indicating cancerous growths in your colon. We offer three types of fecal tests:

    • Stool DNA tests identify specific abnormal DNA genes in the cells shed from cancerous growths or polyps in a stool sample.

    • Fecal immunochemical tests detect blood through a certain immunochemical reaction of protein in your blood and are often able to detect hidden blood.

    • Fecal occult blood tests can detect blood in the feces not visible to normal eyes through a chemical reaction.

There are a few common denominators when it comes to those who are at risk for colon cancer. Although anyone can be diagnosed, colon cancer is commonly seen in those:

  • Over 45 years of age
  • People with ulcerative colitis and Crohn’s disease
  • Men and women with familial adenomatous polyposis, a condition where they develop many polyps in the colon and rectum
  • Men and women with a sedentary lifestyle, bad eating habits, and/or who smoke
  • People who have close family members like parents, siblings, or children who have or had colon cancer
