Early Detection Saves Lives!

Colorectal Cancer Screening


Colorectal Cancer Facts

     A malignant tumor arising from the inner wall of the large intestine

     The third leading cause of cancer in males and fourth in females

     Worldwide, colorectal cancer ranked 3rd (1,230,000 cases per year) in cancer incidence and 4th (608,000 case per year) in cancer mortality

     Most colorectal cancers develop from polyps; removal of colon polyps can prevent the cancer

     Colon polyps and early colorectal cancer can have no symptoms, therefore regular screening is very important

     Colorectal cancer can be present for several years before symptoms develop


Risk factors associated with colorectal cancer (see table):         Average-Risk       0-1                                         

      Older than 50                                                                                          Moderate-Risk     2-3

      African American or Eastern European descent                                     High-Risk              4-7

      Diet high in red or processed meat

      Colorectal polyps

      Crohn’s disease or ulcerative colitis

      Family history of colorectal cancer

      Personal history of breast cancer

      Cigarette smoking

       Alcohol consumption

      Excess body weight (BMI >30)

      Type 2 diabetes



Many cases of colorectal cancer have no symptoms. If there are symptoms, the following may indicate colorectal cancer:

      Abdominal pain and tenderness in the lower abdomen

      Blood in the stool

      Diarrhea, constipation, or other changes in bowel habits

      Narrow stools

      Weight loss with no known reason


Through screening tests, colorectal cancer can be detected before symptoms develop.

This is when the colorectal cancer is most curable.


Screening for Colorectal Cancer

The United States Preventative Services Task Force recommends screening for colorectal cancer from ages 50 to 75 years.  Colorectal cancer screening (colonoscopy, sigmoidoscopy, or fecal occult blood testing) is cost-effective for patients older than 75 who have never been previously screened. 


General methods to screen for colorectal cancer include:

      Fecal occult blood tests (FOBT)  (Annual)


      Standard colonoscopy
