Statins may reduce cancer risk and mortality. A retrospective study of 11 million patients found no increased cancer risk with statin use. Several studies found statins reduced colorectal cancer mortality by 30% and overall mortality by 24%. A study of 22,000 high-risk prostate cancer patients found a 43% reduction in cancer risk with combined statin and metformin use, and a 40% reduction with statins alone. A study of 146,326 postmenopausal women found 23-43% reduced mortality from various cancers with statin use. While early studies linked statins to cognitive issues, recent evidence suggests they may protect against dementia. Meta-analyses of statin trials found no cognitive impairment, and FDA data found similar
