Colorectal cancer (CRC) is une of most common form of cancer.Polyps, non-cancerous growing tissue are often a precursor to colon cancer.Early detection often leads to a complete cure, which is frequently made by colonoscopybased screening.Although almost all men and women age 50 and older are currently recommended to undergo colon cancer screening only less than 50% of the population has been appropriately screened.The availability of an accurate, non-invasive, cost-effective screening tool might increase the number of participants in screening program who are reluctant to undergo more invasive tests.
