Newresearch confirms that sigmoidoscopies -- less-invasive alternatives tocolonoscopies that don't require sedation -- are effective in lowering the riskof colon cancer, which makes genericXeloda even more successful in treating colon cancer. "Physiciansneed to find out which colorectal cancer screening test the patient sitting infront of them will do, and recommend that test," said editorial author Dr.John Inadomi, a professor of medicine at the University of Washington School ofMedicine in Seattle. "It's the test the patient wants to do -- not thetest the doctor wants them to do -- that is important." Colonand rectal cancers kill more than 51,000 people a year in the United States,according to the National Cancer Institute. Colonoscopies allow doctors to viewthe lining of the entire colon as they engage in search-and-destroy missionsagainst polyps that could develop into cancer. To buy Xeloda is then necessary if the polyps couldnt be destroyedduring the procedure. Sigmoidoscopiesuse a smaller scope that searches only the lower colon, potentially missingsome precancerous polyps. Patients can return to home or work right after theprocedure because they are not sedated. "Bothkinds of screening require a notoriously unpleasant cleansing of the colon viaa liquid laxative. However, sigmoidoscopies require less laxative consumptionthan colonoscopies," Inadomi said. Butthere is a hitch to sigmoidoscopies: If the procedure turns up potentiallydangerous polyps, they need to be removed during a subsequent colonoscopy. "Whenit comes to the ability of regular colonoscopies to detect polyps, we may haveto do better," said study author Dr. Robert Schoen, a professor ofmedicine and epidemiology at the University of Pittsburgh School of Medicine."Or maybe we can't do better." Canadapharmacy is very optimistic that one of these days better ways of detectingpolyps will surely be established. Sigmoidoscopy is the minimally invasive medical examination of thelarge intestine from the rectum through the last part of the colon. There aretwo types of sigmoidoscopy: flexible sigmoidoscopy, which uses a flexibleendoscope, and rigid sigmoidoscopy, which uses a rigid device. Flexiblesigmoidoscopy is generally the preferred procedure. A sigmoidoscopy is similarto, but not the same as, a colonoscopy. A sigmoidoscopy only examines up to thesigmoid, the most distal part of the colon, while colonoscopy examines thewhole large bowel.Flexible sigmoidoscopy enables the physician tolook at the inside of the large intestine from the rectum through the last partof the colon, called the sigmoid. Physicians may use the procedure to find thecause of diarrhea, abdominal pain, or constipation. They also use it to lookfor benign and malignant polyps, as well as early signs of cancer in thedescending colon and rectum. With flexible sigmoidoscopy, the physician can seeintestinal bleeding, inflammation, abnormal growths, and ulcers in thedescending colon and rectum. Flexible sigmoidoscopy is not sufficient to detectpolyps or cancer in the ascending or transverse colon (two-thirds of thecolon). However, although in absolute terms only a relatively small section ofthe large intestine can be examined using sigmoidoscopy, the sites which can beobserved represent areas which are most frequently affected by diseases such ascolorectal cancer, for example the rectum.
