There is no modern improvement in screening process that would account for the increase in colon cancer we have been seeing in young adults. Colon cancer screening still does not begin until age 50
Is it only routine screening that would help account for increases or also better detection for symptomatic individuals? Maybe more easily available blood tests or more frequent referrals for colonoscopies for those outside of typical screening groups.
This shows that the colon cancer screening rate has quadrupled for ages 45-49 since 2020. It says official guidelines were changed in 2021.
I am not going to pretend to be an expert, but I also imagine there could be significant difference in how sensitive these screenings have been over the decades.
It's not available to anyone under 45 that it wasn't already (i.e. expressing symptoms, which indicated an advanced status, AKA not a "screening" use case but a diagnostic one)
