In the constant search for better approaches to treat and ultimately prevent prostate cancer, it is essential that we better understand the underlying etiology of prostate cancer. In times like this, I am often discouraged by the common mantra that the only known risk factors for prostate cancer are “age, race, and family history”. Surely, there must be other risk factors. Over time, certain risk factors have revealed themselves – obesity (aggressive prostate cancer), diet (likely, but exact details still evolving), and smoking (aggressive prostate cancer) to mention a few. One common factor, but certainly not the only factor, linking obesity, diet, and smoking is they all increase inflammation. If true that increased inflammation drives more prostate cancer, then it begs the question of whether other conditions that are clearly inflammatory-related are linked with prostate cancer. With this background in mind, Ge and colleagues tested the association between inflammatory bowel disease (IBD) and prostate cancer risk.
