1. Colorectal cancer is predominantly a “man’s disease,” affecting many more men than women annually.

FALSE. Colorectal cancer affects an equal number of men and women. Many women, however, think of CRC as a disease only affecting men and might be unaware of important information about screening and preventing colorectal cancer that could save their lives, says the American Society for Gastrointestinal Endoscopy.

2. Only people over the age of 45 who are currently experiencing some symptoms or problems should be screened for colorectal cancer or polyps.

FALSE. Beginning at age 45, all men and women should be screened for colorectal cancer EVEN IF THEY ARE EXPERIENCING NO PROBLEMS OR SYMPTOMS. In addition, African-American people and all people with a family history of colorectal cancer should be screened earlier. Discuss your individual risk factors with your doctor to determine the appropriate timing and type of your first screening and each screening thereafter.

3. A colonoscopy screening exam typically requires an overnight stay in a hospital.

FALSE. A colonoscopy screening exam is almost always done on an outpatient basis. A mild sedative is usually given before the procedure and then a flexible, slender tube is inserted into the rectum to look inside the colon. The test is safe, and the procedure itself typically takes less than 45 minutes.

4. Colorectal cancer is the second leading cause of cancer death among men and women combined in the United States.

TRUE. After lung cancer, colorectal cancer is the second leading cause of cancer deaths in the United States. Annually, approximately 136,000 new cases of colorectal cancer are diagnosed in the United States and 50,000 people die from the disease. It has been estimated that increased awareness and screening would save at least 30,000 lives each year.

5. Tests used for screening for colon cancer include colonoscopy, fecal immunochemical (FIT) test, FIT-DNA or stool DNA test, FIT-fecal DNA, flexible sigmoidoscopy and CT colonography.

TRUE.  Once CRC has taken hold, there are symptoms. But screening tests can catch cancer in early stages before symptoms appear, or prevent cancer from developing altogether. Talk to your healthcare provider about which test is best for you. Current recommended screening options* include:Beginning at age 45, experts recommend the following as the best tests:

• A colonoscopy every 10 years (the most accurate and the only test that can remove precancerous polyps) OR
• A FIT (fecal immunochemical) test every year. A positive result on a FIT test requires follow-up with a colonoscopy.

For those who can’t or won’t undergo these tests, other options include:

• CT colonography every 5 years
• FIT–fecal DNA test every 3 years
• Flexible sigmoidoscopy (recommended frequency varies from every 5 years to every 10 years)

However, colonoscopy will be needed to follow up on positive results of these tests.

* Important: You may need to begin periodic screening colonoscopy earlier than age 45 years if you have a personal or family history of colorectal cancer, polyps or long-standing ulcerative colitis. For people with certain risk factors, colonoscopy is the only appropriate screening test.

6. Colorectal cancer is often preventable.

TRUE. Colorectal cancer is highly preventable. Colonoscopy may detect polyps (small growths on the lining of the colon). Removal of these polyps (by biopsy or snare polypectomy) results in a major reduction in the likelihood of developing colorectal cancer in the future.  Tests other than colonoscopy are designed to detect cancer as opposed to pre-cancerous lesions that can be dealt with before they become a cancer.

F.Y.I.

The American Society for Gastrointestinal Endoscopy encourages you to talk with your healthcare provider about colon cancer screening and encourages everyone over the age of 45 to undergo the appropriate screening. If your primary healthcare provider has recommended a colonoscopy, you can find a physician with specialized training in these GI endoscopic procedures by using the free Find a Doctor tool.
