You're also more apt to develop colon cancer if a first degree relative (parent, sibling or child) has had the disease. Your risk escalates with each number of family members who has had colorectal cancer. - Certain genetic syndromes passed though family's over a number of generations can increase your risk of colon cancer. These inherited syndromes include familial adenomatous polyposis (when numerous polyps gather in the epithelium of the large intestine) and hereditary nonpolyposis colorectal cancer, which is also known as Lynch syndrome. According to the Mayo Clinic, up to three percent of colon cancers are thought to be caused by Lynch syndrome.
