Crohn’s disease is one of the most significant risk factors that lead to the occurrence of the symptoms of Colon cancer.  Colon is a part of the large intestine and when the abnormal cell behavior such as uncontrolled cell growth occurs in the glands lining the inner wall of the colon, it causes colon cancer. These growths in the inner lining of the colon are known as polyps and these polyps that convert into cancer over time. All polyps do not convert into cancer and the chances of changing into cancer depend on the type of colon cancer. Adenomatous polyps can change into cancer whereas hyperplastic polyps are more common and are not precancerous.
