Group/Cohort Intervention/treatment
Subject aged 45-49 with Average CRC Risk
Subjects will be men and women, 45-49 years of age, who enroll in Exact Sciences Protocol 2018-10. Subjects will provide a blood sample at time of enrollment.
Other: Blood Sample Collection
Subjects participating in the study will have blood drawn at enrollment.

Primary Outcome Measures :
  1. Blood-based biomarkers associated with genetic and epigenetic alterations. [ Time Frame: Point in time blood collection (1 day) at enrollment ]
    Biomarkers under evaluation include differential methylation of nucleic acids and altered expression of proteins in blood from subjects at average risk for development of colorectal cancer.

Biospecimen Retention:   Samples With DNA
Residual blood samples may be used for evaluating performance of biomarkers for feasibility and assay development. Sample may be stored for up to 20 years. These blood samples will be de-identified.
