Dear Jerry.
Thank you for your inquiry and for attending the webinar. At this time we do not offer CEU’s for our webinars. Please visit our https://ce.mayo.edu/ for information about upcoming courses.
Thank you,


Does moving your bowels frequently help lessen the risk of developing colon cancer? Does using a squat potty help?
Thank You

Despite extensive research, there is no convincing link between frequency of bowel movements and risk of colorectal cancer. I am not aware of any research studies that have rigorously evaluated body position during bowel evacuation and colorectal cancer risk. Paul Limburg MD


Can you speak a little about Lynch Syndrome?

Jump to this post

Lynch Syndrome refers to an inherited predisposition to colorectal and other cancers due to a change in one or more genes involved in DNA mismatch repair (a biologic process that helps eliminate cells with errors in their genetic code). Lynch Syndrome can be suspected based on family history, and confirmed using genetic testing. Colorectal and other cancer screening recommendations are different for Lynch Syndrome families than for the general population, so please consult a healthcare provider for a more detailed discussion if you are concerned about possible Lynch Syndrome.Paul Limburg MD


Informative presentation: did not answer one question I have often heard posed. Are there any symptoms that would indicate the presence of colon cancer. Changes in bowel habits? Gastric disturbance>

There are some symptoms that could indicate the presence of colon cancer, such as change in bowel frequency, change in stool size (thin caliber), bleeding per rectum, unexplained weight loss, and others. Unfortunately, these symptoms are neither “sensitive” (they don’t always occur even when colon cancer is present) nor “specific” (these symptoms can be associated with conditions other than colon cancer). If you have any of the above symptoms, or others that you are concerned about, ask your doctor if you need a colonoscopy or other diagnostic test. Paul Limburg MD


I’m 79 years old. Both of my parents had CRC and my mother died of it at 82. At my last colonoscopy, I was told that because I was over 75, I didn’t need any more screenings. I don’t understand his reasoning. Please comment.

Some professional groups, such as the US Preventive Services Task Force, have recommended that colorectal cancer screening can be stopped after age 75 years for average risk persons. However, individual circumstances (family history, personal history, etc.) should be taken into account. Please discuss your risk profile with your doctor to better understand the potential risks and benefits of continued colorectal cancer screening. Paul Limburg MD
