Colonoscopy Benefits Lower Than Expected, Study Shows

Oct. 10, 2022 — Getting a colonoscopy may not provide as many advantages as we beforehand thought of what is taken into account a gold normal in most cancers screening, in accordance with a shocking new examine out of northern Europe. 

After a 10-year follow-up examine of people that had been invited to obtain a colonoscopy, researchers in contrast their outcomes to a gaggle of people that didn’t get the most cancers screening. The former group had solely an 18% decrease danger of getting colon most cancers, and the process didn’t make a lot distinction in colon most cancers deaths, in accordance with outcomes revealed in The New England Journal of Medicine.

“It’s hard to know the value of a screening test when the majority of people in the study didn’t get it done,” says William Dahut, MD, chief scientific officer on the American Cancer Society.

However, examine sufferers who did bear a colonoscopy had a 31% lower within the danger of colorectal most cancers, and cancer-related deaths dropped in half as in comparison with those that weren’t screened. This end result factors to the worth of continued screening.

Getting a colon most cancers screening continues to be one of the best technique of prevention, says Karen Knudsen, PhD, chief government officer on the American Cancer Society.
