It is recommended for use by health professionals as part of routine physical examinations and in screening for colorectal cancer or other sources of lower G.I. bleeding.

Colorectal Cancer: FIT Twice a Year After 50

Moreover, the hybrid screening strategy requires fewer resources than the current CRC screening protocol. The findings are consistent with a recent US Preventive Services Task Force analysis.
The authors compared the hybrid screening strategy with single-modality screening using annual FIT, sigmoidoscopy every 5 years, and colonoscopy every 10 years. They also… Continue reading
