The cause of polyps is not 100% known. We know that there's definitely a genetic component to it because people that have a family history of polyps or a family history of colon cancer have a much higher risk of forming polyps. Many studies have been done to see if there's a dietary component to polyps. We know that red meat and patients that have a sedentary lifestyle with a lot of constipation, they have a higher risk of forming polyps and subsequently forming colon cancer. On the other hand, patients that have regular bowel movements that are on a high fiber diet, they have a slightly decreased risk of forming polyps. So it's a component of environmental and a component of genetic that then leads to the formation of the polyps.
