FIT screening for the early detection of colorectal cancer

OC-Sensor™ is relied upon for FIT screening all over the globe and fulfils all the requirements of the European guidelines for quality assurance in colorectal cancer screening and diagnosis. FIT screening has become the method of choice for the early detection of colorectal cancer (CRC) (Karsa, L. et al. Overview: European guidelines for quality assurance in CRC screening and diagnosis…Endoscopy 2013; 45: 51-59)

Over 120 million people in over 50 countries are screened using OC-Sensor™ every year through established national programmes.

Colonoscopy remains the standard method to diagnose Colorectal Cancer. However, colonoscopy does have limitations, the uptake by patients is very low because the bowel preparation process and the procedure itself are unpleasant for patients. Colonoscopy is an invasive procedure and while minimal, is not without risk.

In most countries, available colonoscopy resource is scarce. By implementing OC-Sensor™, national and regional cancer prevention schemes are able to balance population screening with local infrastructure and resources.
