Colorectal Cancer: Screening

  • Jason F. Hall
  • Thomas E. Read


Cancer of the colon and rectum is the second leading cause of cancer-related death in the USA. In 2009, it was estimated that 147,000 Americans will be diagnosed with colorectal cancer and 50,000 will die from this disease.1 Without undergoing screening or preventive action, approximately 1 in every 17 people in this country will develop colorectal cancer at some point in life. There is clear evidence that colorectal adenocarcinoma can be prevented by detecting and removing adenomatous polyps and that detecting early stage cancers reduces mortality from the disease.2–9 Both polyps and early stage cancers are usually asymptomatic; cancers that have grown large enough to cause symptoms have a much worse prognosis. This contrast highlights the need for screening in asymptomatic persons.
