How preventable is colorectal cancer?

In general terms, can lifestyle changes significantly reduce the risk of colon cancer even with the presence of family history? What are some medically proven methods to prevent it? Can my risk level be confirmed with a Colonoscopy?

Yes, being at a normal weight and eating low-fat foods. In addition, no smoking. However, everyone should still get a Colonoscopy at age 45.

Data suggests that an unhealthy diet (inflammatory diet/high-fat and processed food diet) could increase the risk to develop colon cancer. This could be by changing the microbiome (the balance between good and bad bacteria in the colon). Patients with family history and bad genes are at increased risk regardless of their diet. We don’t have data to prove that changing the diet will decrease the risk for colon cancer in patients with family history of colon cancer.
