Colon Cancer Prevention and Screening
Colon Cancer Screening
Cancer screening exams are medical tests done when you’re healthy with no signs of illness. They help find cancer at its earliest stage, when the chances for curing the disease are best. When it is found early, colon cancer has a good chance for successful treatment. That’s why it is important to get regular tests.
MD Anderson recommends the following screening guidelines for people at average risk with no colorectal cancer symptoms. Beginning at age 50, men and women should follow ONE of these screening schedules:
Colonoscopy every 10 years (preferred by MD Anderson; polyps can be removed during the test)
Virtual colonoscopy (also known as CT colonography) every five years. A colonoscopy will be performed if polyps are found. If you choose a virtual colonoscopy, check with your insurance provider before scheduling an exam. Not all insurance providers cover the cost of this exam.
Fecal occult blood test (FOBT) every year. This take-home test finds hidden blood in the stool, which may be a sign of cancer. A colonoscopy will be performed if blood is found.

To make an appointment for a screening colonoscopy or other colorectal cancer screening test at MD Anderson, call 713-794-5073 or request an appointment online.
Review your screening colonoscopy report and make note of what was found, including the:
- Number of polyps
- Type of each polyp
- Size of each polyp
To get a copy of your colonoscopy report, call the clinic or doctor who did the test. Ask for both the colonoscopy and pathology reports. Share these reports with your doctor at your next check-up. The doctor will use this information to decide if your chances of getting colon cancer are higher than normal.

Colon Cancer Risk Factors
Anything that increases your chance of getting colon cancer is a risk factor. Colon cancer risk factors include:
- Age: Rectal cancer is much more common in people over 50 years old
- Family history of colorectal cancer or polyps
- Inherited disorders such as hereditary nonpolyposis colorectal cancer (HNPCC or Lynch) syndrome or familial adenomatous polyposis (FAP)
- Race or ethnic background: African Americans and Jews of Eastern European descent (Ashkenazi Jews) are at higher risk
- Inflammatory bowel disease (Crohn’s disease or chronic ulcerative colitis)
- Colorectal cancer or polyps
- Lack of exercise
- Diet: If you eat a lot of red meat, processed meats or meats cooked at very high heat, you may be at higher risk for colon cancer.
- Diabetes Type 2
- Cigarette smoking (Read more about MD Anderson’s smoking cessation clinical trials)
- Drinking too much alcohol
For patients who are concerned about inherited family syndromes that cause colon cancer, we offer advanced genetic testing to let you know your risk.
