Perhaps the people who chose to take colonoscopy before age 45 are a specific subset, not characteristic of entire population.... so recommendations based on this “a postiori” analysis are skewed/not valid.
I say this because I chose to take the colonoscopy at age 45 because grandmother was diagnosed & treated for colon cancer.
I was confused by the conflicting claims that there is a “troubling increase” in polyps, yet this is the first large scale study of the age group.
To what are they comparing this study in order to come to the conclusion that there is a “troubling increase?”
Normally, you would need to compare the results of this study to past studies of a similar nature before you could confidently detect a trend.
