The Use Of Colonoscopy Reduces The Risk Of Colon Cancer – Part 2 of 3
The American Cancer Society recommends that normal-risk men and women be screened for colon cancer, starting at lifetime 50. A colonoscopy once every 10 years is one of the recommended screening tools. However, there has been some debate as to whether colonoscopy – an invasive and expensive procedure – is certainly preferable to other screening methods, such as flexible sigmoidoscopy.
Based on a review of medical records of 1688 German patients aged 50 and over with colorectal cancer and 1,932 without, the researchers found a 77 percent reduced endanger for this type of malignancy among people who’d had a colonoscopy in the past 10 years, as compared with those who had not. The lion’s share of the benefit was seen for left-sided cancers, although there was still a 50 percent reduction on the above-board side (only 26 percent among those aged 60 and younger).
No one knows why colonoscopy seems to be superior in detecting problems on the left affectation of the colon. “There are a number of potential reasons. It may be that the biology is conspiring to make it harder. The polyps look different, grow differently. Also, the quality of the laxative studying tends to be less effective than on the other side so you might be more likely to miss something”.
