Colorectal Cancer is the abnormal growth of cells or tumor formation in the giant intestine (massive bowel or colon) and the rectum. These cells can spread (metastasize) and damage other tissues or organs in the body; thus, often called cancer cells. Fundamentally, the colon serves as storage site for the feces before being excreted from the body, while the rectum is the distal finish of the colon that is adjoining to the anus. These structures of the digestive tract are the main sites for Colorectal Cancer, but cancer cells can also metastasize to the liver, lungs and other vital organs. Consequently, injury to the different body organs caused by cancer cells leads to several organ dysfunctions that can result to a person’s death.
According to the World Health Organization (WHO), cancer is of the leading causes of death across the globe, in Western countries such as the United States. In fact, in year 2008, 13 percent (13%) or 7.6 million of the total deaths of people worldwide is due to cancer. Among over hundred types of malignancies, Colorectal Cancer lands at the fourth spot of the most common cancers among men and ladies.
The most common causes of cancer are as follows
• genetic or hereditary origin;
• High dietary fat intake;
• low-fiber diet (low vegetable and fruit consumption)
• polyps (non-cancerous tumor) that are not removed from the colon; and
• Ulcerative colitis
Studies revealed that people with relatives history of colon cancer are high risk of developing the disease. Another cause of colon cancer is high overweight dietary intake. Various researches show that the metabolism (breakdown) of fats results to the production of free radicals or carcinogens, which are substances that cause cancer. Meanwhile, low fiber dietary intake is usually associated with poor bowel movement resulting to diminished ability of the body to eliminate waste products including carcinogens. Cancer in the colon and rectum is also believed to be a complication of Chronic Ulcerative Colitis (bowel inflammatory disease) and polyps that have not been removed.
