I had a recent colonoscopy. Turned 50 this year. Anyway, the colonoscopy revealed 5 polyps, 2-3 cm in size. The Dr. removed all 5, they were examined, and determined they were precancerous. Also, it was stated, there may have been smaller polyps, that could not be seen, therefore they were not removed.
A followup colonoscopy is reccomended in 3 years. I just have concerns about waiting that long.
