6. Colon Cancer Polyp growth and irregular cells are the most common development paths for colorectal cancers and can be detected during a routine colonoscopy. Genetics Oncotype Dx® Colon Cancer Assay, ColoPrint®, and ColDx™)have been developed that look at the activity of many different genes in colon cancer tumors. Staging Treatment Newer surgery techniques Laparoscopic surgery is done through several small incisions in the abdomen instead of one large one, and it's becoming more widely used for some colon cancers. With robotic surgery, a surgeon sits at a control panel and operates very precise robotic arms to perform the surgery. This type of surgery is also being studied. Immunotherapy

7. Diverticulosis/Diverticulitis Small pouches may form along the walls of the large intestine called diverticuli which cause discomfort to the patient (diverticulosis). These abnormal out pocketing may collect and not be able to empty fecal material which can lead to inflammation. Scientist doesn’t know what causes 1 theory was low-fiber diet However a recent study found that a low-fiber diet was not associated with diverticulosis and that a high fober diet and more frequent bowel movements may be linked to an increased rather than decreased.
