It is well established that aspirin reduces pain, limits the inflammatory response, and reduces cardiovascular disease but that it can lead to major bleeding events and gastrointestinal upset. For several years increasing numbers of studies have suggested a benefit of aspirin on the occurrence of polyps and colorectal cancer.2 3 Potential beneficial effects on other common cancer types have also been reported.4 Two recently published large scale studies have provided additional evidence that low dose aspirin reduces the incidence of cancer, death from cancer, and cancer metastasis.5 6
