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.

Colon cancer   i had a colonoscopy 31/2 yrs. Ago but am having trouble lately could polyps grow that quickly i won't have another colonoscopy for 6 mo?

The more the number of polyps seen and removed, the higher the growth rate and likely the chance of finding new ones. Having polyps or cancer at a young age though should trigger shorter intervals to surveillance colonoscopies. ...Read more
