What can be done to prevent the disease?
Research findings show that eating a diet high in fiber and getting enough calcium can help prevent colorectal cancer. Use of aspirin and vitamin E are also associated with a lower risk of colorectal cancer.
Early diagnosis is key to preventing death from this disease. Starting at the age of 40, people should have yearly digital rectal exams and fecal occult blood tests. This screening allows early detection of colorectal polyps. These precancerous lesions can be removed before they turn into colorectal cancer.

People who are at high risk for colorectal cancer because of family polyp syndrome or ulcerative colitis often choose to have the colon removed. This is called a colectomy.
