 Don't ignore colorectal cancer screening
Most people would probably answer, “Yes, of course.” However, while colorectal screening has been shown to be effective in reducing the risk of death, many remain hesitant to have such tests. Their reasons for hesitating range from apprehension and embarrassment about colorectal cancer screening tests, such as colonoscopies, to natural reluctance about undergoing testing when they feel healthy and show no symptoms of disease. But if you are over age 50, regardless of how you feel or any other factors, it makes sense to be screened for colorectal cancer. In fact, it may save your life. You may be at risk for colorectal cancer even if you have no history of the disease in your family, or if you have no obvious symptoms, such as a change in bowel habits or blood in the stool. In fact, the CDC estimates that roughly 75 percent of colorectal cancers occur in people with no known risk factors. Colorectal cancer affects both men and women of all racial and ethnic groups. People over age 50 are at the greatest risk for colon cancer, as well as people with:
Does colorectal cancer screening really work?
Statistics indicate that screenings work, as the rate of new cases and deaths from colorectal cancer declined by almost 5 percent since the period between 2002 and 2004. Still, more than 147,000 new cases are found each year, and over 57,000 people die from colorectal cancer each year, according to the National Cancer Institute. The following are screening tests for colorectal cancer:
Digital Rectal Exam – This is an exam of the rectum done in a doctor’s office. A lubricated, gloved finger is inserted into the rectum to feel for lumps or anything else that seems unusual. Flexible Sigmoidoscopy – Prior to taking this test, a strong laxative or enema must be used to clean out the colon. This test is conducted in a doctor’s office, clinic, or hospital. The doctor inserts a narrow, flexible, lighted tube to look at the inside of the rectum and the lower portion of the colon. Polyps may be removed during the test and tissue samples collected for further examination. This test is recommended every five years. Combination FOBT and Flexible Sigmoidoscopy – Some physicians believe taking both tests increases the chances of finding polyps and cancers. Colonoscopy – Prior to taking this test, you need to take a strong laxative to clean out the colon. This test is usually conducted in a clinic or hospital. Many times, a sedative is given to make you more comfortable during the test. Most times the sedative will make you drowsy and unable to drive yourself home after the test. The test is similar to the flexible sigmoidoscopy, except that the tube used is longer and enables the physician to see the entire colon. The colonoscopy is often used as a follow-up when other tests determine a need for it. A colonoscopy is recommended every 10 years. Double-Contrast Barium Enema – This test is conducted in a radiology center or hospital. Prior to the test, you need to use a strong laxative or enema to clean out the colon. During this procedure you are given an enema with a barium solution, followed by an injection of air. X-rays of the rectum and colon are taken. The barium coats the lining of the intestines so that polyps and other abnormalities are visible. The test is recommended every five years. Computed Tomography (CT) Colography – Also known as a “virtual colonoscopy,” this new technique takes computer-generated x-ray images after air is injected into the colon. |

There are things you can do that may reduce your risk of contracting colorectal cancer. The Centers for Disease Control and Prevention (CDC) recommends increasing your physical activity, eating fruits and vegetables, limiting alcohol consumption, and avoiding tobacco. Studies have shown that maintaining a healthy weight and increasing physical activity can decrease risk. If you are over 50, or have other risk factors for colorectal cancer, you should obtain a screening.
