Colonoscopies are regarded as the "gold standard" for colorectal cancer screening, and a new study published April 3rd in the New England Journal of Medicine demonstrates just how effective they can be in the prevention of colon cancer.
The research was conducted by Douglas Corley, MD, PhD of the Kaiser Permanente Division of research in Oakland, CA. The findings showed that the more non-cancerous growths physicians removed on colonoscopy, the lower the chances that patients would later develop cancer. For every 1 percent increase in adenoma detection through colonoscopy, there was a 3 percent lower risk for colon cancer.
An adenoma is a type of polyp that grows along the wall of the colon. These polyps, or tissue growths, can be benign but if left undetected or ignored can become cancerous.
"These findings support the validity of the adenoma detection rate as a quality measure of physicians' performance of colonoscopy in community practice, and suggest that the development and testing of interventions to improve the adenoma detection rate are warranted," researchers concluded.
They also added that their finding that there was a relationship between adenoma detection and lower risk for later cancer diagnoses adds more support for the recommendation of colonoscopies.
If you are 50 years or older, discuss colon cancer screening with your doctor.
