(Reuters) - U.S. President George W. Bush on Saturday had five small polyps removed while he underwent a colonoscopy exam, a routine check for colon cancer. Following are some facts about colon cancer:
-- An estimated 153,760 Americans will be diagnosed with colorectal cancer this year, and 52,180 Americans will die from the disease, the American Cancer Society says.
-- It is the third most commonly diagnosed cancer and the second leading cause of cancer deaths in the United States, after lung cancer.
-- Colonoscopies are screening tests that can detect the disease at its earliest, most treatable stage or even prevent it by removing precancerous growths called polyps.
-- Colonoscopy is advised for everyone 50 and older.
-- The procedure requires the patients to cleanse the bowels first, usually by taking a strong laxative or enema and then sticking to clear fluids for the day before the exam.
