The results of our comprehensive meta-analysis show that red meat or processed meat consumption is not associated with increasing the risk of prostate cancer. A very weak, albeit statistically significant, summary association was observed for processed meat and total prostate cancer, although not for advanced or fatal prostate cancer. There was no evidence of a dose-response relationship between processed meat and total prostate cancer in meta-regression or stratified intake analyses; however, future studies with more detailed intake data would facilitate a more comprehensive evaluation of any possible dose-response patterns, particularly by prostate cancer sub-types, such as high-grade tumors. In addition, we did not observe any significantly elevated associations in the meta-analyses of cooking methods, heterocyclic amines, and total and advanced prostate cancer, although we did observe a weak association between total mutagenic activity and total prostate cancer, based on limited data. Heterocyclic amines and methods of cooking meat at a high temperature or until well-done have often been suggested as risk factors for prostate cancer. However, the results of these meta-analyses do not support that hypothesis. Based on the findings from this meta-analysis, and given the relatively large volume of prospective cohort studies, red meat or processed meat intake do not appear to be associated with increasing the risk of prostate cancer.
