Polyps are abnormal growths that develop within the colon and rectum. Certain types of polyps can develop into cancer if not removed. If a screening isn t suggested to an individual, Dr. van Stolk says patients should request it from their physicians. Removal of polyps at an early stage has been proven to prevent cancer. The removal of polyps is absolutely painless, assures Dr. van Stolk.
Family history is a critical factor in whether one is likely to develop colorectal cancer.
When individuals have a family history of the disease or known polyps, their risk of developing colorectal cancer is three times as great, and they should begin screening at age 40 or even earlier. Several screening tests are used to help identify the presence of precancerous polyps in the colon or rectum. There are several procedures, from the simple test for blood in the stool to the more involved sigmoidoscopy and colonoscopy. The more basic test should be performed annually, while the other options are needed at less frequent intervals. Some screening tests can be conducted in a primary care practitioner s office while others require a visit to a specialist or to a facility such as Northwestern Memorial s Colon Cancer Screening Center.
