why do you have to get a colonoscopy

When Should I Have One? Your doctor may recommend your first colonoscopy at age 50, because most people who get colorectal cancer are older than this. But, if you have a close relative (like a parent, sibling, or child) who has had colorectal cancer, or if youвre African-American, you may be advised to start earlier (African-Americans are more susceptible to the disease). The good news is that you only need to do this test once every 10 years, unless the doctor finds any polyps the first time. Then you might need to have your second colonoscopy within 3 to 5 years. There are other ways to detect A fecal occult test checks a stool sample for blood.


It needs to be done annually. Fecal immunochemical test (FIT) uses to detect blood in your stool. Itвs also done once a year. FIT- is a combination of the FIT with a second test that looks for altered (cancerous) DNA in your stool. Itвs done every 1 to 3 years. CT Colonography uses X-rays and computers to give your doctor images of your entire colon to analyze. A is similar to a colonoscopy, but it examines your rectum and only part of your colon. It can be done by a primary care physician and doesn't involve sedation. However, you still have to prepare your bowels in advance. If a is found, you're still going to need a colonoscopy to have it removed.


The same is true if blood is found in your stool sample. That's why the colonoscopy is considered the gold standard because it combines detection with treatment. The most common reason people give for not having a colonoscopy is that their doctor never mentioned the test to them (the second reason is the bowel prep). So, if your doctor is advising you to get this test, you're already ahead of the game. Now you've just got to deal with the bowel prep. Fortunately, there are a number of different preparation methods out there. Check with your doctor for the best one for you. It's a small price to pay for cancer prevention.
