They require further screening to determine if the non-colonic polyps have malignant potential and if cancer has developed outside of the gastrointestinal tract. HNPCC is suspected because other family members also have colon cancer and certain criteria are met (Amsterdam or Bethesda criteria), or the cancer shows a particular pattern under the microscope with special stains. Colon cancer is a growth of abnormal cells in the colon, which multiply causing cancerous tumors. Bowel regularity means a bowel movement every day. They all make recommendations on the basis of factors such as family history of polyps and colon cancer, the number of polyps that are found, the size of the polyps, and the polyps' histology. Genetics also may be used in other ways. Colectomy is performed under general anesthesia and may require hospitalization for up to a week or more. If more than ten adenomas are found, it is recommended that a second examination be done in three years or less. Concerns are greater (and the interval to the next examination should be shorter) if the polyps are proximal (in the ascending colon), are larger (more than one centimeter in size), and particularly if they show dysplasia. Initially, the increasingly, genetically abnormal cells are limited to the layer of cells that line the inside of the colon. Endoscopic colonoscopy involves the use of a colonoscope, a flexible tube approximately five feet in length with a light and camera at the end and a hollow channel through which instruments can be passed. Treatment of blood in the stool depends on the cause.

A colonoscopy is a type of endoscopy. There is some concern about using calcium since higher dietary and supplemental levels are associated with an increase in vascular disease. The effect is likely to occur with higher doses of aspirin (more than the 81-325 mg that is recommended for cardiovascular disease prevention), and there is concern about aspirin's side effect of gastrointestinal bleeding at these doses. colitis,
Normally, the immature cells lining the colon are programmed to divide (multiply), mature, and then die in a very consistent and timely fashion. Polyps don't always become cancerous, but your risk of developing cancer increases with the number and size of colon polyps you have. The results of the colonoscopy and histologic examination are important because they determine the need for increased frequency of screening colonoscopy in the future (for example, adenomatous polyps). If one or more adenomas are found and any show high grade dysplasia, a second examination is recommended in three years. Colon polyps can vary in size from a few millimeters to several centimeters. Genetics and genetic testing have become an important aspect in the evaluation of both colon polyps and colon cancer. In addition, genetic testing can be done for relatives of the patient to determine whether or not the relative has the same mutation as the patient and, therefore, is very likely to develop polyps and cancer. For that … There are several means to diagnose colon polyps. FOBT is primarily used to detect colon cancer.
