Core tip: With increasing economic burden of cancer care, cost-effective, preventive strategies are in focus. Commonly used drugs like statins, metformin and aspirin have been shown to have anti-neoplastic effects and are attractive candidates for cancer chemoprevention and reducing cancer-related mortality. Recently, in a Danish nationwide population-based cohort study, statin users had 15% reduction in all-cause and cancer-specific mortality as compared to non-users. These results are encouraging and show that statin use may be associated with reduced cancer mortality across different subgroups and cancer sites. However, several confounding variables remain, which merit further evaluation before this can change clinical practice.
