". if you look back to the 1890s,
you can find colorectal cancer rates as high as those
being found in Generation X and Millennials recently.
Young and middle-aged adults are showing
patterns in these cancers not seen in over 100 years,
according to the authors of a recent study.
Lead author Rebecca Siegel, of the American Cancer Society noted,
“People born in 1990 now have double the risk of colon cancer
and quadruple the risk of rectal cancer
compared to people born around 1950.”
about 14,000 cases of colorectal cancer per year
occur in people younger than 50
. if it was the obesity rates
driving up the colorectal cancer rates,
we would expect to see a time-lag
where colorectal cancer incidence followed obesity rates
by 10 or 20 years,
allowing for causality from obesity to result in colorectal cancer.
But these two trends appear to have increased at about the same time"

this article points out that inflammation
could increase the risk of colon cancer.
. coincident with increased obesity
is increased preference for artificial sweeteners:
sucralose is known to cause gut dysbiosis,
and inflammatory bowel disease,
