Colon cancer is malignant tumor in the lining of the large intestine. It begins with a single cell that changes forms and grow into a visible polyp. Polyps can grow into cancerous tumors and must be removed. If a polyp is allowed to remain in the colon and they are cancerous tumor it can further attack other organs. Medical researchers do not understand how a polyp can progress into cancer, but it is know that it takes about 3 to 7 years for a polyp to become cancerous.
