What Causes Colon Cancer?


What causes colon cancer?


Colon cancer, also referred to as adenocarcinoma of the colon, is a malignant tumor that starts in the colon or large intestine.

Colorectal cancer is another commonly used term that includes colon cancer, but also cancers that begin in the rectum. The rectum is the end of the large intestine where stool is excreted through the anus.

The following factors are associated with the increased risk of having colon cancer:

1. Age and Aging

Age is the NO.1 risk factor for colon cancer. About 81 percent of cases occurred in people over 45 years old.

2. Alcohol Consumption

Risk of having such a cancer is directly associated with the amount of alcohol consumed.

3. Diabetes Risk

Diabetics are prone to developing colon cancer because insulin dependency contributes to the development of the disease.

4. Dietary Factors

High-fat foods can turn normal cells into stem cells which then may convert into tumors. A diet low in fiber, fruits, and vegetables is also linked with an increased risk.

5. Ethnicity and Race

African Americans are 40% more likely to develop colon cancer than whites and have 20% greater risk of death. On the contrary, Asians are known to be at lower risk, compared with all other groups.

6. Family History of Colon Cancer

If you have a family history of colon cancer, your chance of getting the disease is higher than those who don’t.

7. Inflammatory Bowel Disease

The longer a person has had Inflammatory bowel disease (IBD), the greater his or her risk of developing colon cancer.

8. Obesity and Cancer Risk

People who are obese are prone to develop this kind of cancer than people of normal weight.

9. Precancerous Polyps

A colon polyp is a small clump of cells that takes shape on the lining of the colon. Virtually all colon cancers develop from non-cancerous adenomatous polyps which can suddenly turn malignant as they grow bigger.

10. Smoking Risk

Long-term smoking is linked with the accelerated polyp growth.
