Researchers Scour Century-Old Tumor Samples for Clues on Rising Colorectal Cancer Rates Among Young Adults
A puzzling trend is unfolding among younger adults: colorectal cancer rates are surging at an alarming rate. Despite overall declining rates of the disease, those under 55 are now seeing a 1% to 2% increase each year since the mid-1990s. In fact, nearly one in five cases are diagnosed in individuals under 55 – making it the leading cause of cancer death among men aged 50 and younger, and second among women in the same age bracket.
The reasons behind this disturbing trend remain a mystery. Researchers point to potential culprits like increased ultra-processed food consumption, sedentary lifestyles, and rising obesity rates. However, the exact link between these factors and colorectal cancer remains unclear.
Enter an unlikely source of answers: the basement archives at St Mark's National Bowel Hospital in London. The hospital boasts an astonishing 10,000+ tumor tissue samples and gut bacteria preserved from every patient treated for colorectal cancer – a veritable "treasure trove" of data waiting to be unraveled. By analyzing these century-old samples using molecular DNA analysis, scientists hope to uncover the patterns behind shifting trends in younger adult cases.
Intriguingly, researchers have identified a type of gut bacteria (E. coli) now present in people's bowels but not previously. This microbe may emit toxins that stimulate the growth of cancerous cells – a hypothesis being tested by experts at the Institute of Cancer Research. By scouring these ancient tumor samples, scientists are determined to shed light on this enigmatic phenomenon and uncover the underlying causes driving the rising rates of colorectal cancer among younger adults.

This is wild! I'm literally shook that we're seeing a rise in colorectal cancer cases among young adults 
It's like, what's going on?! The fact that researchers are looking at century-old tumor samples for clues 
is actually kinda genius 
I mean, who knows more about the human body than our own cells? 
And the idea that this gut bacteria (E. coli) might be linked to the growth of cancerous cells 
is a total game-changer! 
We need to get to the bottom of this ASAP and find ways to prevent it from happening to more people

. It's gotta be something we're not eating or doing that's causing this to happen... maybe it's the all-you-can-eat pizza and Netflix binges? 
Anyway, I think these researchers are onto something with those century-old tumor samples! 
. All these factors - ultra-processed food, sedentary lifestyles... it's like we're sleepwalking into a giant health disaster. And now they're talking about some crazy gut bacteria and cancer cells? Like, we need ancient tumor samples to figure this out? 
. It's like, the old saying goes... "you can't know where you're going unless you know where you've been" 
It's not like the doctors are giving me any answers, but at least they're trying to figure it out. Fingers crossed they find a solution soon! 
all these ultra-processed foods can't be good for us. and don't even get me started on sitting around all day watching tv 
. at least they're trying to figure out what's going on with those ancient tumor samples 
. Researchers are on the right track by looking back at old tumor samples - it's crazy how much data is just collecting dust in hospitals 
. The idea that some new gut bacteria might be causing the problem is super intriguing 
Anyway, back to this weird gut bacteria thing... if it's emitting toxins that cause cancer, shouldn't our phones have some sort of warning system for that? Like, an alert that says "Hey, you might be about to grow a tumor"?
