A new study by Canadian researchers published in The American Journal of Gastroenterology reveals colonoscopies may miss nearly 8 percent (or one in every 13) of colon cancers, according to The AJC.
The study, " Rate and Predictors of Early/Missed Colorectal Cancers After Colonoscopy in Manitoba: A Population-Based Study," looked at close to 4,900 colorectal cancers in patients 50-80 years of age diagnosed between 1992-2008 and assessed how long after a colonoscopy was performed before these cancers were identified.
Cancers diagnosed within six months of a colonoscopy were categorized as detected and those found 6–36 months after a colonoscopy were determined to be early/missed cancers.
Of the 4,883 cancers included in the study, 388 (7.9 percent) were determined to be early/missed CRCs.
