Participants who are at high risk of developing colorectal cancer will be asked to collect two stool samples one for the stool DNA test and the other for the commercially available FIT assay, and a single blood sample for the blood mRNA test. Subjects will undergo colonoscopy within 6 months of enrollment. Representative histopathology slides from tissue biopsied or excised during colonoscopy and those from subsequent definitive surgery may be retrieved in order to be evaluated by pathologists to confirm the diagnosis and staging.
