While colonoscopy is effective in preventing cancers and advanced polyps in the lower part of the colon and rectum, it is less successful in stopping them in the right side or upper colon.

Looking back at almost 3,300 colonoscopies performed in community gastroenterology practices in Germany, researchers found a substantial reduction in large polyps or cancers in the left side of the colon and rectum among patients who had had a colonoscopy in the past ten years compared to those who hadn’t had one.

However, in the upper part of the colon, risk for an advanced polyp or cancer was the same whether or not the patient had a previous colonoscopy.

Overall, colonoscopy reduced the risk of a cancer or an advanced adenoma by 50 percent.

That makes sense, it saves money, and it saves lives.

We applaud the President’s public acknowledgment that colorectal cancer screening saves lives and money.

Screening saves lives by finding cancers early when they are most treatable.  Screening also prevents colorectal cancer by finding and removing precancerous polyps, which keeps them from ever growing into cancer.

This week we review research on the impacts of colonoscopy screening in Germany, folic acid flour supplementation in Chile, and untreated anxiety and pain during the last months of life on surviving spouses of cancer patients.

In the news are reports of colon cancer surgery using a tiny incision in the belly button, requirements for KRAS testing before insurance will pay for Erbitux or Vectibix treatment, and information about how stem cells in the intestinal tract become cancer stem cells, driving the development and progression of colorectal cancer.
