A Century-Old Tumor Sample Puzzle May Hold Clues to Younger Adults' Colorectal Cancer Surge
Colorectal cancer rates have been on the rise among adults under 55, with one in five cases now diagnosed at a younger age. This trend is alarming, especially considering that colorectal cancer has become the leading cause of death from cancer among men under 50 and the second most common among women in this age group.
Despite overall declining colorectal cancer rates, research suggests that increased consumption of ultra-processed foods, sedentary lifestyles, and rising obesity rates may all be contributing factors. However, the underlying reason for the surge in cancer rates among younger adults remains unclear.
To uncover the truth, scientists are turning to a unique resource - a century-old tumor tissue sample archive stored at London's St Mark's National Bowel Hospital. The hospital's basement archives contain tens of thousands of paraffin-preserved samples and gut bacteria from every patient treated for colorectal cancer, making it the most valuable resource globally.
The Institute of Cancer Research in the UK has been sent these samples for molecular DNA analysis to study how patterns of colorectal cancer have shifted over time. Researchers hope that analyzing these ancient tumor tissue samples will shed light on whether a particular type of gut bacteria, E. coli, is contributing to the rise in cases.
According to Trevor Graham of the Institute of Cancer Research, this "treasure trove" of bowel tissue samples may hold the key to understanding how patterns of colorectal cancer have changed over time. By testing these hypotheses, scientists aim to uncover new insights into the rising rates of colorectal cancer among younger adults.

I'm kinda worried about this trend, especially since I know people my age who've already gotten sick from it. Colorectal cancer is like, super scary 
and we shouldn't have to deal with it at such a young age. The fact that scientists are using ancient tumor tissue samples to study the issue makes sense, but I'm not sure if it's gonna be enough to make a real difference.
. Eating all that processed food and sitting around for hours on end isn't doing us any favors. Maybe if we can figure out what's causing the rise in cases, we'll be able to come up with some new ways to prevent it.
. That would at least give us something to work with. But overall, I think this is a good start – scientists are trying to figure out what's going on and that's gotta count for something 
Like, they're already going through so much stress and anxiety. We need all the help we can get right now! Fingers crossed that these researchers can find something new to share with us soon. This is like the ultimate detective mystery, but instead of solving crimes, they're trying to solve the puzzle of cancer 
. But seriously, if it means finding answers and potentially new treatments or prevention methods, then let's do it 
. I'm keeping my fingers crossed that these ancient samples hold the secrets to this mystery... Fingers crossed for young people everywhere 
... hope the researchers find out if E. coli is a factor in this growth... feel like we need more awareness about how our food choices affect our health 
also, why are they focusing on younger adults now? whats going on behind the scenes? is this part of some bigger plan? 
, hope they can crack the code with these ancient tumor samples 
What if this research leads us to some revolutionary new way to prevent or treat colorectal cancer? The thought sends shivers down my spine! 
. It's like, we need to make some serious changes ASAP! 
Do you think our current diet and lifestyle habits are contributing to the rise in Colorectal Cancer among younger adults? 
but at the same time, it's kinda wild that we're only just now realizing how much ultra-processed foods and sedentary lifestyles are messing with our guts 
.
I had no idea they were studying old tumor samples from 100 yrs ago!! 
Okay not literally but for real though! 
Did u know there are over 10k samples stored in one place?! 
Let's hope the researchers find out what's going on and can help save more lives! 
Fingers crossed for a breakthrough! 
thingy! A century-old tumor sample archive? That's like, so old it's new news 
.
