9. Colorectal cancer often develops from polyps in the intestinal lining. What is a polyp and why might a polyp become cancerous? The last part of the gastrointestinal tract (GIT) is the large intestine. The large intestine is a long muscular tube mainly consists of colon, cecum, rectum and anus in the end. The colons main function is to absorb nutrients, water and lubrication of the feces so the bowel movement can be easily made. Sometimes protruding structure may develop inside the lumen (bowel cavity). They look like small bumps along the internal lining of the intestine which are mainly called polyps. They may develop on the small stalk like a mushroom and may be flat like a bump. Most of the times the polyps are noncancerous such type of polyps are known as hyperplasic. While the other type of polyps which raises the risk for colorectal cancer are known as adenomatous polyps. The adenomatous polyps are larger in size from more than an inch which may develop small areas of cancer. Most polyps do not cause any symptoms but the larger adenomatous polyps may cause blood in the stool. Therefore, such polyps may have to be removed during the colonoscopy (American Society for Gastrointestinal Endoscopy).
