An Aspirin a Day Keeps the Colorectal Polyps Away

A national study indicates that patients who have had previous colorectal cancer and take 325 milligrams of aspirin each day — the equivalent of one adult aspirin — may lower the risk of developing new colon polyps by 35 percent. Polyps appear to be precursors to most colorectal cancers. The double-blind study randomly assigned half of the 635 patients who previously had colorectal cancer to an aspirin treatment group. The other half received a placebo or sugar pill. The results of the study will be published in the March 6, 2003, issue of the New England Journal of Medicine.
