Introduction. The National Cancer Institute of Canada NCIC acknowledges colorectal cancer as the third most common cancer and the second most common cause of death from a cancer among men and women in Canada, second only to lung cancer. If, however, the cancer is detected early through screening, it may be highly treatable and need not be deadly. In a majority of cases, colorectal cancer is preventable and yet each year in Canada, thousands of people are diagnosed with advanced colorectal cancer. The majority of colorectal cancers begin as benign growths in the lining of the large bowel wall called adenomatous polyps. Over the years at least ten years, these polyps grow in size and number, thereby increasing the risk that the cells in the polyps will become cancerous and invade the wall and move on to other organs. Approximately two thirds of these cancers are found in the large intestine and one third in the rectum. Early removal of these growths will prevent colorectal cancer from developing in the first place. Hence, identification and removal of polyps are key to preventing the development of colorectal cancer. Clearly, being screened as part of a regular physical exam has the potential to save lives and patients who are experiencing symptoms related to colorectal cancer should not delay accessing a screening test nor should patients who are at higher risk of developing the cancer. Briefly, the risk factors for colorectal cancer are Age the older you are, the more likely you are to develop colorectal cancer. Heredity you are more likely to develop colorectal cancer if someone in your family, especially a first degree relative child, sibling, parent has been diagnosed with it. Diet a diet high in red meat and low in fruits and vegetables may increase you risk. Weight obesity and a lack of physical activity increase the risk. Alcohol Consumption alcohol, especially beer, may increase the risk. Lower rates of colorectal cancer have been found in those who drink no alcohol. Download Game Love Chess. Smoking smoking also increases the risk of developing colorectal cancer. Enough cannot be said about the importance of screening in preventing, detecting and curing colorectal cancer. It is simply the best line of defense when it comes to protecting oneself from this deadly disease. Screening is clearly the best way to stop colorectal cancer in its tracks or prevent it from developing in the first place which is why the Colorectal Cancer Association of Canada CCAC has developed the following content providing information on the various colorectal cancer screening tests as well as a summary of the recommended guidelines overseeing the administration of the screening tests.

Screening for colorectal cancer allows for the early detection of cancer when it is highly curable, as well as the detection of growths polyps that might eventually become cancer. These polyps may be removed preventing the cancer from developing altogether. There are several tests used to screen for colorectal cancer and polyps. Appearing below is a summary of the various types. Guaiac Fecal Occult Blood Test g. FOBTOne of the presentations of colon cancer is chronic blood loss in the stool. Sometimes, such blood loss is so minimal, it cannot be seen when the stool is inspected in the toilet. Hence, a stool sample may be collected which is returned to the doctor or lab to test for occult hidden blood. The guaiac fecal occult blood test uses the chemical guaiac to detect heme in stool. Heme is the iron containing component of the blood protein hemoglobin. The other type of FOBT, called Fecal Immunochemical Test, is explained below. The idea behind the g. FOBT is that blood vessels at the surface of larger colorectal polyps or cancers are often fragile and easily damaged by the passage of feces. The damaged vessels usually release a small amount of blood into the feces, but only rarely is there enough bleeding to be noticeable in the stool. This test, however, cannot determine whether the blood is from the colon or from other portions of the digestive tract such as the stomach. Therefore, if the test is positive, a colonoscopy is required to determine if there is a cancer, polyp, or other cause of bleeding such as ulcers, hemorrhoids, diverticulosis tiny pouches that form at weak spots in the colon wall or inflammatory bowel disease colitis. Source http health. FOBT is done with a take home kit that can be used in the privacy of the patients home. People having this test will receive a kit with instructions explaining how to take a stool or feces sample at home usually specimens from 3 consecutive bowel movements that are smeared onto small squares of paper. The kit should then be returned to the doctors office or medical lab usually within 2 weeks for testing. Supplies will include a test kit, test cards, either a brush or wooden applicator, and a mailing envelope. The instructions below can be used as a guide, but the instructions on the kit might be a little different depending upon province and manufacturer. Provincial screening programs have specified laboratories to carry out the work on the sample and it is important to follow the specific instructions of the program when returning the sample, including the accompanying paper work. FOBT Instructions You will need to collect a sample from your bowel movement. You can place a sheet of plastic wrap loosely across the toilet bowl to catch the stool or you can use a dry container to collect the stool. Do not let the stool specimen mix with urine. After you obtain a sample, you can flush the remaining stool down the toilet. Use a wooden applicator or a brush to smear a thin film of the stool sample onto one of the slots in the test card or slide. Next, collect a specimen from a different area of the same stool and smear a thin film of the sample onto the other slot in the test card or slide. Close the slots and put your name and the date on the test kit. Store the kit overnight in a paper envelope to allow it time to dry. Repeat the test on your next 2 bowel movements as instructed. House Vs Hurricane Crooked Teeth there. Most tests require collecting more than one sample from different bowel movements. This improves the accuracy of the test because many cancers dont bleed all of the time, and blood may not be present in all stool samples. Place the test kit in the mailing pouch provided and return it to your doctor or lab as soon as possible but within 1.
