Core Tip: Diabetes mellitus (DM) is a chronic metabolic disease caused by many factors. Prostate cancer (PCa) is a common malignant tumor in men and is the second leading cause of cancer death. The Mendelian randomization (MR) method uses genetic variation as an instrumental variable to detect and quantify causal relationships, which can avoid the impact of confounding factors on the accuracy of the research results. This makes it more reliable than observational study or even randomized controlled trial. This study aimed to clarify the relationship between DM and PCa using MR analysis. Through MR analysis of a large sample with three different methods, this study found that DM was an independent risk factor for PCa, providing new directions for the prevention and treatment of PCa.
