Official Title: Calcium, Vitamin D, and Colon Cancer Risk Biomarkers

Brief Summary: The purpose of this study is to test whether calcium and/or vitamin D supplementation favorably affects a set of biomarkers of risk for colon cancer in persons who are at higher than average risk for colon cancer (ie, have already undergone the removal of adenomatous polyps, which are known to be precursors to developing colon cancer).
