How do you know if you have a family history of colon cancer if all the old folks get colonoscopies, get polyps removed, and say nothing about it?

Ask: Go to your older relatives & ask them- not just about colonoscopies, but about their parents/grandparents, who had what & who died from what. You'll get valuable family history on a number of topics. Only about 5% of colon cancers occur in families with a history of colon cancer, so screening is more important than family history for this. ...Read more

I am considering a screening sigmoidoscopy over that of a colonoscopy due to more preparation and procedural involvement. No family history. Wise?

Colonoscopy : I would suggest a colonoscopy if you are able, as it is a more complete screening. If normal you will not need another for 10 years. The sigmoidoscopy only looks at the lower portion of your colon. ...Read more

If there is past family history of 2 deaths from bowel perforation (1 colonoscopy, 1 cdif) could there be increased risk for other family members?

If there is past  family history of 2 deaths from bowel perforation (1 colonoscopy, 1 cdif) could there be increased risk for  other family members?

Not clear: If i understand what you are asking, there is no risk to have bowel perforation because others had it. Specially from a colonoscopy. Cdiff is an infection and the only risk is to get the infection from the relative that had it. ...Read more
