When we reach certain age it advised by medical professionals to get colonoscopy at least every 3 years to screen for colon cancer which is reported to be the third most common cancer in the United States. Colonoscopy involves using a flexible, lighted tube to see inside the colon, is the most effective tool for the early screening of colon cancer. The process of going through the test can be embarrassing for some people, thanks to science now moving towards a urine test to detect colon cancer.
The article from ScienceDaily (Apr. 21, 2010) — Scientists are reporting an advance toward development of a urine test for detecting colon cancer. Such a test could eventually compliment or even reduce the need for colonoscopy, the mainstay screening test used today. when scientists analyzed urine samples from 123 people 60 with colon cancer and 63 without, for differences in its composition. They identified 16 substances that appear in unusual amounts in colon cancer. The changes include increased levels of tryptophan, one of the 22 amino acids that are found in proteins. The results demonstrate the potential of using urine as a tool for diagnosing colon cancer as per involved scientists .
This is good news, it will reduce the pain, fear/anxiety or embarrassment that goes with the actual colonoscopy test. I guess this could also save a lot of money and time because patients will now be able to just provide urine sample for their initial assessment and probably not to undergo the colonoscopy unnecessarily .
