The most accurate and recommended test is the colonoscopy, a small light-and-video probe that is inserted into the anus and gently threaded through the entire length of the colon. This allows for clear visualization of the colonic tract and any polyps there may be, which can be removed on the spot before they turn cancerous.
This procedure is usually performed under sedation so it is painless, with the only post-procedural discomfort being a bloating sensation.
People with no other risk factor besides age should typically get their first colonoscopy at 50, at 10-year intervals. Those with high risk factors, however, should get screened earlier and at shorter intervals.
With this method, air is first pumped into the colon to inflate it. The patient will then lie on his back and then on his stomach in the CT scanner, which will capture and generate a virtual image of the colon.
Some people opt for this method as they are afraid of a colonoscopy; but do note that should abnormal growths be found during a CT colonography, a colonoscopy will still have to be conducted anyway to remove those growths.
Here, a tube will be inserted into the anus and a bag of white liquid (barium) will be poured in, filling up the colon. The patient will then be rotated so the barium can flow through the colon properly. Thereafter, the barium is drained and air will be pumped in, inflating the colon for a clearer view. The doctor will that proceed to take X-ray images in various angles.
This is a safe and quick test that can detect the presence of small amounts of blood in the stool which are not visible to the naked eye. It functions on the assumption that the bleeding may be due to bleeding in the lining of the colon, caused by the presence of a polyp. Though it is not a conclusive test for colorectal cancer, it does serve as a good warning sign for one to go for more detailed tests.
