Annual stool testing and other screening methods are also critically important. The nutrients folate, also known as folic acid, and calcium can also lower the risk of colon cancer. Most studies show that as dietary or supplemental intake increases, the risk of both polyps and colon cancer decreases. Surprisingly, several large studies did not show a benefit of fiber or vitamins A, C, D, and E for colon cancer prevention. During the last 20 years, postmenopausal hormone-replacement therapy has been credited for the decline in colon cancer among women.
Doctors say aspirin protects against heart disease as well.
And all the better if it reduces the risk of colon cancer. But early detection is the best way to prevent colon cancer death.
