Colonoscopies work – they detect cancer before it becomes cancer, while it’s still treatable and curable. If you’re over 40, ask your doctor. If you’re over 50, get one done. If anyone in your family tree has had colon cancer or polyps – ask your doctor when you should start. This is serious – I’m not joking! The full article is here.

ScienceDaily (July 24, 2012) — A study from researchers in Switzerland found that colonoscopy with polypectomy significantly reduces colorectal cancer incidence and colorectal cancer-related death in the general population. A total of 12 colorectal cancer cases were identified in the screening group of 1,912 patients and 213 cases of colorectal cancer were found in the non-screened group of 20,774 patients. One of the 12 persons of the screened individuals with a colorectal cancer and 51 of the 213 persons of the non-screened individuals with a colorectal cancer died because of their cancers. The study appears in the July issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).
