Colon cancer and its risks must be known to every one. Not only male or female, but also aging people should know the risk factors of the cancer and how to cure it. This article will discuss screening guidelines available today in the medical world.
There are three ‘colorectal’ screening guidelines that are commonly practiced today. Screening is recommended for those aged 50 and above or at a younger age if there is a family history of colon cancer. However, there are certain guidelines for these screening methods.
The first being ‘colonoscopy’. ‘Colonoscopy’ is a procedure in which a long flexible viewing tube (a ‘colonoscope’) is inserted through the rectum to inspect the entire colon and rectum (anus). Tissue samples from growths arising from the inner lining of the rectum and colon can be obtained during the procedure. This procedure may be done every three to five years.
The second screening method is called ‘sigmoidoscopy’. It is rather similar to the earlier described ‘colonoscopy’. The former is different in that this screening technique examines the large intestine from the rectum through the last part of the colon. There are two types; flexible and rigid. Similarly to ‘colonoscopy’, it may be performed every three to five years.
Lastly, faecal occult blood test is performed to detect colon cancer. This test is done to look for microscopic blood in the stool. It requires the collection of a stool sample that will be tested. The faecal occult blood test can also help indicate other gastrointestinal problems that could be causing the symptoms seen. This particular test should be done annually.
