Available Screening Tests
There are a variety of different methods that can be used to screen for colon cancer, all of which have proven to be very effective. For instance, you could be provided with a stool test, which searches for blood in the stool. While the presence of blood doesn’t always mean that colon cancer is present, it does make it more likely. You could also be provided with a sigmoidoscopy, which is a test that uses a flexible scope to look at the lower portion of your colon. This screening will oftentimes be used once you’ve been provided with a stool test. While a sigmoidoscopy is effective, it’s unable to identify cancer in the higher areas of the colon.
Another common screening used for colon cancer is a colonoscopy, which is able to view the entire colon. The bowel will need to be cleansed before this screening can be administered. Since the entirety of the colon is able to be viewed with a colonoscopy, this test is considered to be the most effective. It’s recommended that you obtain a colonoscopy or similar type of screening every 5-10 years to make sure that you don’t have this type of cancer.
