I went through three articles apparently rehashing the same scientific publication:
https://www.thesun.co.uk/living/3018803/lazy-millennials-face-a-bowel-cancer-time-bomb-thanks-to-poor-diet-and-booze/https://uk.news.yahoo.com/colon-rectal-cancer-rates-among-181003746.htmlhttp://www.seacoastonline.com/news/20170305/colorectal-cancer-rates-risingIt seems to me that such sensational conclusions were mainly due to inability of the modern journalists to read and comprehend scientific papers.
The latest article seems the most trustworthy to me. Its main conclusion is:
"With colorectal cancer rates increasing for people in their early 50s but decreasing for those in their late 50s, the study found a strikingly smaller gap in incidence within just that decade of life.
The younger group's rate used to be half that of the older group; it now is just 12 percent lower."
So it's about comparison of the number of cancer diagnosis in people 50 to 54 years old and 55 to 59 years old.
Is it possible that such dramatic outcome was caused by routine colonoscopies in people older than 50?
In this case it's possible that in people 50 to 54 y.o. colonoscopies discovered early stage cancer that could have been diagnosed at a later age with more advanced stage without colonoscopy.
I would like to see a more detailed analysis paying attention to staging at diagnosis as well.
58 yo male at diagnosis: T1bN0M0, 0/15 nodes, low grade/moderately differentiated adenocarcinoma
03/2016 colonoscopy: 2 small polyps removed in left colon; CEA = 1.3
04/2016 colonoscopy: caecum sessile 3.5 cm polyp piecemeal removed with kind of clear margins
05/2016 "prophylactic" laparoscopic right hemicolectomy - bleeding, leak, infection
06/2017 CT scan, colonoscopy OK; CEA = 1.6
A lot of funny stuff discovered by CT scans in liver, kidney, lungs, arteries, gallbladder, lymph node, pancreas
