How Your Weight Can Contribute to Colon Cancer

There are many known causes of colon cancer, also known as colo-rectal cancer. Your lifestyle and family history are probably the two largest causative factors. If your family has a history of colon cancer, you need to be very careful with your diet and habits. Smoking and alcohol usage are also significant causative factors that can determine whether or not you contract colon cancer. One of the main causative factors in developing colo-rectal cancer is your weight. Men have also been shown to be more susceptible to colon cancer. If you’re overweight, studies show that you’re much more likely to contract colon cancer than someone who is at or just above her optimal weight.

The Colon

The colon is the last part of the human digestive tract where solid waste is stored prior to excretion. The rectum lies at the end of the colon, right before the anal sphincter. This is why colon cancer is sometimes referred to as colo-rectal cancer.

Fruits and Vegetables

People who are obese or significantly overweight typically don’t have a diet that is high in fruits and vegetables. These foods are high in dietary fibers and essential vitamins and nutrients that help keep you free of carcinogens and adenomatous polyps, which have been shown to be present in the vast majority of colon cancer cases. In fact, almost every case of colo-rectal cancer is preceded by the formation of polyps. Carcinogens are cancer causing agents or chemicals in the body. Adenomatous polyps are growths on the inner lining of the colon.

Fat Content of Foods

Studies show that people who are obese or extremely overweight don’t eat or prepare foods that are healthy. This may be because healthy foods usually tend to take a little longer to prepare and don’t always taste as good as unhealthy foods. Studies have shown that in cultures where dietary fat intake is extremely high, the number of cases of colo-rectal cancer is also disproportionately high. Medical science believes that the products created during the process of digesting fats increase the risk of polyp development and the formation of colon cancer cells. Lowering the overall fat content of your diet will significantly decrease your risk of colon cancer.

Low Fiber Diets

Foods such as candy, crackers, chips and hamburgers aren’t very high in dietary fiber. Dietary fiber is a required part of a healthy diet that is normally lacking from the dietary habits of people who are significantly overweight. Fiber digests slower and helps cleanse the digestive system of harmful chemicals, including carcinogens. If you feel that you are in a high risk group for colon cancer, you should make sure that your diet contains a high amount of dietary fiber.


Cholesterol is known by many in the medical community to be a silent killer. Hardening of the arteries. Arterial blockages. Heart disease. These are just a few of the laundry list of health problems that cholesterol can cause. Colo-rectal cancer is another of the health problems attributable to cholesterol. Medical science believes that chemicals left over from the metabolism of cholesterol may have carcinogenic factors.
