Results of two new studies have found that statin drugs do not help prevent cancer as well as some earlier studies might have suggested. Although preliminary studies showed lower rates of breast, prostate and colon cancers among statin users, a recent analysis of 26 studies involving 87,000 patients concluded the drugs had no impact on cancer rates, according to a report published in the Journal of the American Medical Association (JAMA). Another study, conducted by the American Cancer Society and appearing in the current issue of the Journal of the National Cancer Institute, reviewed data on more than 130,000 patients in the US and found no effect on colon cancer rates between those who used statins and those who did not.
