Colonoscopy exams get a bad rap.
Even though the exam is brief and painless, many people fear and avoid them. Roughly 40 percent of Americans for whom they are recommended are not getting colonoscopies.
Yet colonoscopy is one of the most effective of all cancer prevention methods. The American Cancer Society estimates there will be 142,820 diagnoses of colorectal cancer in 2013 and 50,830 people will die of the disease. As many as 60 percent of colon cancer deaths could be prevented if everyone 50 years old or above underwent colonoscopies, according to the Centers for Disease Control and Prevention (CDC).
