    It depends. Individuals with no family history of colon cancer or who are not of African-American descent are encouraged to schedule their first colonoscopy at age 50. African-Americans or those with a family history of colon cancer should schedule their first colonoscopy at age 45.

    If your initial colonoscopy is clear and there are no polyps detected, you should schedule your next colonoscopy in 10 years. However if polyps are detected during your colonoscopy, your physician will recommend you follow up within 1-5 years, depending on the type of polyp.

    A colonoscopy is used to identify (and remove) precancerous polyps or early cancers. You should have a colonoscopy every 10 years starting at age 50. Alternatively, you may get a flexible sigmoidoscopy every five years, a double-contrast barium enema every five years or a CT colonography (virtual colonoscopy) every five years. However, a colonoscopy will be needed if any of those results are positive.

    Every ten years, starting at age fifty. If one of your close family members developed colon cancer before age sixty, or if you have ulcerative colitis, then you may decide to have a colonoscopy before you turn fifty.

    If polyps are found and removed during the colonoscopy, your physician may have you follow up in 3 to 5 years for surveillance as the presence of polyps predisposes you to the formation of new polyps. Biopsy results take about one week to come back. If no polyps are found and you do not have a family history of colon cancer, your next colonoscopy should be 7 to 10 years after your first one.

    For average risk patients, the first colonoscopy should take place at age 50. After that, and without any symptoms, the next colonoscopy should be 5-10 years later. For high-risk patients (personal or family history of colon cancer, certain genetic disorders) colonoscopy may need to be earlier and more frequent. If symptoms develop then you should consult your doctor to see if colonoscopy is needed sooner.

    This depends on your risk factors for colon cancer but typically, without any family history, you should have a colonoscopy every 10 years after the age of 50. If there is a family history or a personal history of premalignant polyps then a colonoscopy should be scheduled more frequently.

  • Beginning at age 50, both men and women at average risk for developing colorectal cancer should have a colonoscopy every 10 years. The risk of developing colorectal cancer increases with age, with more than 90 percent of cases occurring in persons aged 50 or older.
    Men and women should begin screening earlier and more often if they have any of the following colorectal cancer risk factors: a family history of colorectal cancer or polyps, a known family history of inherited colorectal cancer syndromes, a personal history of colorectal cancer, or a personal history of chronic inflammatory bowel disease (ulcerative colitis or Crohn's Disease). People with risk factors for colorectal cancer or family history of colorectal cancer should talk with a gastroenterologist about screening at an earlier age and find out how often they need to be screened.
    If a polyp is removed during colonoscopy, the patient will receive a report indicating the type of polyp removed. There are several different types of polyps, which are growths in the lining of the colon.  One type of polyp – called an adenomatous polyp (or adenoma for short) – is a benign precancerous growth which may develop into colon cancer in the future if not removed.
    Removal of an adenomatous polyp prevents that polyp from becoming cancerous, but the patient is still at risk to develop new polyps in the colon. Close follow-up is recommended. The presence of a polyp only means that the patient is at risk for colorectal cancer.  It DOES NOT mean that he or she will get cancer, however, continued follow-up with a doctor is important to minimize the risk of developing colorectal cancer in the future. If there is a family history of colorectal cancer, the interval for a follow-up exam may be shortened.
    Individuals at any age with certain symptoms should speak with a physician. The following symptoms might indicate colorectal cancer:  Blood in your stools, narrower than normal stools, unexplained abdominal pain, unexplained change in bowel habits, unexplained anemia, and unexplained weight loss. These symptoms may be caused by other benign diseases such as hemorrhoids, inflammation in the colon or irritable bowel syndrome. If you experience any of these symptoms for more than a few days, talk to a gastroenterologist.
