The best way to stop colon cancer before it starts is by removing polyps that can grow in the lining of the colon and rectum. These growths typically do not produce symptoms, which is why early and regular testing is crucial to preventing this second-leading cause of cancer-related deaths in the United States.
Screening Is Essential
Below are the four ways to be screened for colorectal cancer and recommendations for when and how often the tests should be performed. Keep in mind that regular testing should begin at age 50.
- Stool Blood Test: This very simple method tests a sample of the patient's stool for traces of blood that can't ordinarily be seen. Blood in the stool doesn't always mean cancer, but it does suggest more tests be given. This test is recommended once a year.
- Flexible sigmoidoscopy: Using a flexible scope, the physician can see directly inside a portion of the colon. This procedure should be done ever five years along with a stool blood test. Learn more >
- Barium enema: Combining barium and air enables the physician to spot contrasts in the lining of the colon. Abnormal areas may indicate cancer. This procedure is recommended once every five years. Learn more >
- Colonoscopy: Similar to a flexible sigmoidoscopy, this procedure uses a scope to view the entire colon and remove polyps. This test should occur once every 10 years. Learn more >
Colorectal cancer is usually curable when detected early. In fact, more than 90% of patients with localized colorectal cancer confined to the colon and rectum live for at least five years after the diagnosis.
