How much does a family history of colon cancer increase my risk of getting it?

Varies: The "family history" of colon cancer needs to be further clarified as to what type of family syndrome this is. A genetic counselor can help further define the risks and potential surveillance or treatment strategies. The increased risk may be small or may be very large. Specific genetic testing may be indicated. ...Read more

Can you explain hereditary colon cancer?

Can you explain  hereditary colon cancer?

Not in 400 character: Many genes are linked with an increased risk of colon cancer (and others), so those with a family history of colon, uterine and other cancers are at increased risk as they may inherit these genes from their parents. Genetic testing can pinpoint some of these genes and thus indicate whether you are at increased risk, thus allowing earlier detection/prevention/treatment so get checked if this appies. ...Read more

Is it recommended to get a colonoscopy at age 43 if there is a  family history of colon cancer? What other tests are needed at this age?

10 years before diag: A basic guideline is that in the case of a potentially inherited cancer trait, that we start screening 10 years before the presentation of a first degree relative, i.e. Parent or sibling. If the relative was diagnosed with colon cancer at age 53, we consider beginning screening tests at 43. Otherwise begin screenings as age appropriate, colonoscopy age 50, mammo age 40. ...Read more

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?

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

Is it safe or a good idea to get a colonoscopy before pregnancy or after giving birth? I'm 34/f with family history of colon cancer.

Is it safe or a good idea to get a colonoscopy before pregnancy or after giving birth?  I'm 34/f with family history of colon cancer.

1st colonscopy @ 35: With a family history of colon ca, screening begins at @ 35. Hopefully you won't have polyps (like me). As long as you're not pregnant it should be safe. But remembering "those days", i'd do it before not after. The risk is really being too busy and forgetting or not having the time to have the procedure. ...Read more
