Colon cancer forms in the tissues of the colon, the longest part of the large intestine. Colon cancer is also referred to as colorectal cancer -- cancer that starts in either the colon or the rectum. Colon cancer and rectal cancer have many features in common.


[edit] Why should I be aware of this?

  • Colon cancer accounts for 14 % of all deaths resulting from cancer, making it the second most common cause of cancer death in the US.
  • Colorectal cancer is the third most common amongst newly diagnosed cancer cases.
  • People with a family history of colon cancer may be able to reduce their risk of developing the disease with a few simple dietary changes.
  • Early detection of colorectal cancer helps in better managing the disease.

[edit] How does this affect me?

  • In the year 2002, colorectal cancer was the third and fourth most common cancer in females and males, respectively, worldwide.
  • Its prevalence is second only to that of breast cancer, with an estimated 2.8 million persons alive with CRC within five years of diagnosis.
  • The highest incidence rates occurred in North America, Australia, Western Europe and Japan.
  • The incidence tends to be low in Africa and Asia and intermediate in the southern parts of South America.
  • Geographic differences for colorectal cancer are probably explained by dietary and other environmental exposures.
  • A higher risk of colorectal cancer was found in subjects consuming a diet poor in fiber and rich in meat and fat.

[edit] All about colon cancer

Colon cancer is a common type of cancer in which there is uncontrolled growth of the cells that line the inside of the colon or rectum. Colon cancer is also called colorectal cancer.

  • The colon, also known as the large intestine, is the last part of the

digestive tract.

  • The rectum is the very end of the large intestine that opens at the anus.

[edit] Where Does Colon Cancer Begin?

Colon cancer begins on the inner surface of the colon or rectum. Virtually all colon cancer develops from mushroom-like growths that can grow on the inside wall of the colon.

[edit] Who is at risk?

A person is more likely to develop colorectal cancer in following cases:

  • Diet high in fat
  • Diet low in fruits and vegetables
  • Diet comprises well-cooked, fried or barbecued meats.
  • More than 2-3 servings of red meat in a week.
  • Smoking
  • Drink more than one alcoholic drink a day
  • Does not exercise
  • 50 years old or older
  • Family member had polyps or colorectal cancer before
  • Chronic inflammation of the colon such as “Ulcerative Colitis”, “Crohn’s Disease” or “Irritable Bowel Syndrome”.
  • Incidence of breast cancer, ovarian cancer, cancer of the uterus in the family.

[edit] Symptoms

The symptoms of colon cancer can be confused with those of a number of digestive disorders. If a person has these symptoms he may either have colon cancer or some digestive disorder. It is better to consult a doctor if a person has any of these below mentioned symptoms.

  • Bleeding from the rectum.
  • Changes in bowel habits which change from diarrhea to constipation and back.
  • If the stool is unusually narrow.
  • Pain in the abdomen or rectum
  • A feeling that a bowel movement cannot be completed
  • Unexplained weight loss, anemia, paleness, fatigue, or a yellowish coloring of the skin or whites of the eyes.

[edit] What can I do?

[edit] Prevention

  • Take a daily multivitamin with folic acid or foliate.
  • Exercise
  • Eat less red meat, just 2-3 servings per week. Red meat includes beef, pork and lamb.
  • Eat 5 or more servings of fruits and vegetables a day.
  • Eat deep fried food less often, and eat less fatty foods.
  • Quit smoking.
  • Drink less than one alcoholic drink per day

  • Scientists also have found that low foliate in the diet increases the risk of developing colon cancer in adults. [1]
  • Those who had consumed diets higher in processed meats showed a greater risk of developing recurrent colorectal cancer. Those with diets high in certain white meats, like chicken, were less prone to this risk.[2]
  • A seven-year study led by Dartmouth Medical School researchers shows that a daily dose of aspirin can be effective in reducing the risk of benign tumors of the colon that can develop into cancer if left in the bowel. [3]
  • Calcium supplements moderately reduce the risk of recurring polyp growth in the colon and appear to reduce the risk of colon cancer, according to a new national study.[4]
  • Eating fruits and vegetables was not strongly associated with decreased colon cancer risk, according to a study.[5]
  • Researchers at the University of Michigan Comprehensive Cancer Center are beginning a study to look at whether diet can impact a person’s risk of developing colon cancer. Specifically, the researchers will compare a Mediterranean diet – high in olive oil, nuts and fish – with a standard healthy eating plan to see if it prevents colon cancer.[6]
