Colon on an X-Ray-Red part is the Cancerous Ask Your Doctor: Colorectal Cancer ( Taken from New York Times Article May 1, 2007) 1) When should I start being screened, how often should I be tested and which test is best for me?
2) Are there colorectal symptoms that should prompt me to see a doctor?
3) How long does it take for the doctor to examine the colon during a colonoscopy? (A recent study indicated that doctors who take fewer than eight minutes are most likely to miss polyps.)
4) Will the doctor provide a written report of my test results in layman's English?
5) How likely will this test give a false-positive result - mistakenly indicating that something is wrong - or a false negative, which fails to diagnose a cancer or precancerous condition?
