Colon cancer screening involves a variety of tests used to screen an individual for the early discovery of colon cancer. It can involve a straightforward stool test to check for bleeding, called fecal mysterious blood test (FOBT). On occasion in individuals with colon cancer, this test alone may be adequate to raise a suspicion for the diagnosis.
However, in general FOBT is not an exceptionally touchy test and cannot be routinely depended upon to make an accurate diagnosis of colon cancer. As of late, a test called Cologuard which combines mysterious blood as well as hereditary mutation of colonic cell in the stool has been produced as a non-invasive screening test for colon cancer.
All the more generally, an endoscopic examination of the inner lining of the colon is prescribed for colon cancer screening using a colonoscope. In colonoscopy, an adaptable tube with CCD camera at the distal end is inserted into the anus and advanced all through the colon, for a careful visualization of the lining of the large inside. Most agree that colonoscopy is the highest level examination in colon cancer screening .
On the other hand, sigmoidoscopy is an examination that evaluates just the distal 1/3 of the colon. Since the examination just involves a segment of the colon, it cannot be viewed as an ideal screening test and in this way is just rarely used as a screening test for colon cancer.
Colon cancer is a malignant tumor that forms from the large intestine’s inner wall. The tumor attacks tissue that is in close closeness, and spread to other parts of the body. Polyps are amiable tumors, which means they do not contain cancer. They do not threaten life and can easily be uprooted. They can get to be cancerous if not taken care of in a convenient fashion.
One sort of colon cancer screening strategy is fecal mysterious blood tests, which are chemical-based and performed on the stool samples to search for mysterious blood – amounts so small they can’t be seen by the naked eye alone. The tests check three different examples. If the test is sure, the patient will have a colonoscopy done to search for abnormalities.
If no abnormalities are found, the following step is an examination of the stomach and the small intestine to check whether they are conceivable wellsprings of the bleeding. There’s also a screening called adaptable sigmoidoscopy, which utilizes a fiber-optic viewing tube that uses light at its tip. This strategy takes a gander at the rectum and the bit of the colon that is nearest to the rectum. About half of the colorectal cancers and polyps are found in close closeness to the viewing area of the sigmoidoscope.
Present day innovation allows for a virtual colonoscopy. This colon cancer screening method uses images of the colon that are like perspectives gathered at a colonoscopy. A scanner is utilized to create two-dimensional images, instead of getting an immediate view through the colonoscope. Read here for more detailed information about colon cancer screening.
