Use of colonoscopy for colorectal cancer screening could explain a significant decrease in the cancer's incidence over the past decade, according to a new study from researchers at the Stanford University School of Medicine. Although colonoscopy is now the most common colorectal cancer screening method, there has been conflicting evidence as to its effectiveness compared with sigmoidoscopy, a method that examines only a portion of the colon. The team scrutinized data collected from more...

Two studies by neurological researchers at Rush University Medical Center suggest that, in the future, colonic tissue obtained during either colonoscopy or flexible sigmoidoscopy may be used to predict who will develop Parkinson's disease, a neurodegenerative disorder of aging that that leads to progressive deterioration of motor function due to loss of neurons in the brain that produce dopamine, a neurotransmitter essential to executing movement. Currently, Parkinson's disease afflicts...

Colonoscopy may be preferable to sigmoidoscopy for these populations Blacks and Hispanics have a significantly higher risk of developing precancerous colorectal polyps compared with whites, according to a study by researchers at NewYork — Presbyterian Hospital/Columbia University Medical Center.

Colon cancer is largely preventable as long as a person gets screened appropriately, said a gastroenterologist from the NCI-designated Dan L. Duncan Cancer Center at Baylor College of Medicine. Despite new options for screening, there is plenty of evidence to support that a traditional colonoscopy is still the best method of prevention, said Dr. Bincy Abraham, assistant professor of medicine — gastroenterology at BCM. March is National Colon Cancer Awareness Month. It serves as an...
