A new non-invasive test allows the detection of colorectal cancer with high sensitivity.
Current colorectal cancer screening tests, which use only fecal blood, are biologically limited in their ability to detect precursors of colorectal cancer.
This new test can also detect precancerous lesions with an increased risk of developing into colorectal cancer.

By combining these measures, the types of biological changes that are most common in precancerous lesions and colon cancer can be searched for.
The authors analyzed more than 1000 patient samples, and by analyzing samples with a confirmed colonoscopy diagnosis, they developed an analytical algorithm, which allows a high detection rate for cancers and pre-cancers.
The control group included 796 patients with negative colonoscopies or small polyps (less than 1 cm), and the study group included 207 patients with confirmed colorectal cancer or precancerous lesions.
The researchers reported that the test detected 98% of all cancers, as well as 83% of precursors with high-grade dysplasia and 57% of precursors of 1 cm or more overall.
