There are chances of colorectal cancers getting missed out in patients undergoing colonoscopy when it is performed by people other than a gastroenterologist or a surgeon. This was disclosed by a report published in the journal gastroenterology by Canadian researchers.
This study was conducted on 12,487 colorectal patients by Linda Rabeneck of University of Western Ontario along with her team. According to this study, new cases of colorectal cancer were diagnosed within six months to 3 years of having undergone colonoscopy in 3.4% patients.
Recurrence of this cancer was high in patients suffering from diverticular disease. Right sided colorectal cancer is likely to get missed out generally if colonoscopy is performed by an intern or at the office premises.
Colonoscopy is a procedure which aids in detection of colorectal cancer and the type of colorectal polyps which are likely to turn into cancerous cells by inserting an illuminated tube with a camera in the bowl.
This detection procedure is generally recommended to people when they are around 50 years unless there is a family history of the same wherein it is done earlier than this. If everything is normal, the test should be repeated once in five years.
