Personal History of Colon Cancer
A person who has already had
colon cancer may develop
colon cancer a second time. Also, women with a history of cancer of the ovary, uterus, or breast are at a somewhat higher risk of developing colon cancer.
Ulcerative Colitis or Crohn's Disease
A person who has had a condition that causes inflammation of the colon (such as
ulcerative colitis or
Crohn's disease) for many years is at increased risk of developing colon cancer.
Diet
Studies suggest that diets high in fat (especially animal fat) and low in calcium, folate, and fiber may increase the risk of colon cancer. Also, some studies suggest that people who eat a diet very low in fruits and vegetables may have a higher risk of colon cancer. More research is needed to better understand how diet affects the risk of colon cancer.
Cigarette Smoking
A person who smokes cigarettes may be at increased risk of developing polyps and colon cancer.
Causes of Colon Cancer: Monitoring Your Condition
While there are no known causes of colon cancer, people who think they may be at risk should discuss this concern with their doctor. The doctor may be able to suggest ways to reduce the risk and can plan an appropriate schedule for checkups.
