What Are The Types Of Colon Cancer Screening Methods?

Colon cancer screening involves looking for signs and precancers in the colon and the rectum, before any patient experiences symptoms. It is much easier to treat colorectal cancer if it is caught early. The U.S. Preventive Services Task Force recommends that all adults undergo regular colon cancer screening. While you are probably familiar with colonoscopy, there are many other ways to screen for colorectal carcinoma.

Types of Colon Cancer Screening Methods:

Stool Tests:

A stool test involves testing of intestine cancer poop specimens for hidden blood. These tests only detect blood but do not reveal what part of the intestine or what the source of the bleeding is. These tests can detect large polyps and colon cancers. The stool test is not meant to be used in place of a regular colonoscopy. If blood is detected, your doctor will likely recommend a colonoscopy.

Colonoscopy:

Your gastroenterologist will examine the colon for signs of cancer. Your doctor will insert a thin flexible tube with a camera attached (called a coloscope) into the rectum. Your doctor will remove any polyps found and send them to a laboratory for further testing. These tests will tell you if the polyp is cancerous or benign.

Computed Tomography Colonography:

CT colonography (also known as virtual colonography) uses CT technology to create multiple cross-sectional images. These images are then combined to create detailed images that cover the entire length and width of the colon. These images are used by your doctor to detect abnormal tissue or polyps that may be precancerous. The colon is slightly inflated with air to show small wall defects. A colonoscopy is required for any abnormally appearing lesions.
