In a shocking reversal, colorectal cancer rates among young adults are on the rise. For decades, experts have been warning about the dangers of an increasingly sedentary lifestyle, rising obesity rates, and an alarming shift in eating habits towards ultra-processed foods. However, it's only now that researchers are finally getting to the bottom of this mystery.
Tens of thousands of tissue samples from patients treated at a London hospital dating back up to 100 years have been unearthed in the basement archives of St Mark's The National Bowel Hospital. These ancient tumor samples hold the key to understanding why colorectal cancer rates have skyrocketed among people under 55, with one in five now diagnosed with the disease by age 55.
The data paints a stark picture: while overall colorectal cancer rates have been declining, they've been increasing at an alarming rate for young adults since the mid-1990s. The American Cancer Society has warned that men under 50 are now more likely to die from colorectal cancer than ever before, with women in the same age bracket ranking second on the list.
Researchers are stumped as to why this trend is happening, and experts point fingers at a number of culprits – including increased consumption of ultra-processed foods, sedentary lifestyles, and rising obesity rates. But it's not just about what we eat or how much we exercise; researchers believe that an overabundance of gut bacteria may be playing a role in the rise of colorectal cancer among young adults.
Scientists at the Institute of Cancer Research have been analyzing DNA samples from these ancient tumor tissue samples, and one hypothesis is that a particular type of E. coli, a type of bacteria not previously present in the population, may be emitting toxins that lead to the growth of cancerous cells. By studying these samples, researchers hope to uncover new insights into how patterns of colorectal cancer have shifted over time.
While this study has the potential to reveal some disturbing truths about our collective health, it's also a testament to the power of old-fashioned detective work – and the willingness of researchers to dig through decades-old tissue samples to get to the bottom of a pressing public health mystery.

. I mean, I knew we were living in an age where everyone's always glued to their screens, but this is just crazy! It's like they're playing with fire and not even realizing it 
. All these processed foods are basically poison for our bodies, and now we know that there's some kind of bacteria out there that's causing all sorts of problems? No wonder the rates are rising 
.
. Nowadays, it's all about convenience and speed, but at what cost? 
I just hope they listen to these researchers and start making some changes before it's too late 
... what's going on with our gut bacteria? Is it really as simple as an overabundance of E. coli emitting toxins that lead to cancerous cells? I don't know, but I'm not holding my breath for a solution anytime soon 
...
This is some crazy stuff, right? I mean, colorectal cancer rates have been going up for young adults and it's not just about how much we eat or exercise... maybe our gut bacteria are the real culprit? 
It's mind-blowing to think that there's a type of E. coli out there that's producing toxins that can lead to cancer. We've been warned about this stuff for years, but I guess it took decades-old tissue samples to finally figure out what's going on. 
Now we just need to find a way to stop it from happening in the first place... 
. And what about the pesticides and chemicals we're exposed to daily? Those things are messing with our systems and I'm not surprised to see a correlation between those factors and an increased risk of cancer. We need more scientists looking into this stuff, not just relying on the old "eat less processed food" advice

This is really interesting 
That's wild. I just hope researchers can figure out a solution soon, 'cause we're all gonna be worried sick 
what if its our own bodies doing us in lol idk im just worried rn
. I mean, I grew up with my parents always telling me to eat more fruits and veggies, exercise regularly... it all sounds so basic now 
. But seriously, the thought of young adults dying from colorectal cancer is just mind-blowing 
. It's like we're playing with fire without even knowing it 
.
I mean, I know experts have been warning about this stuff for years, but to actually see the data and realize that one in five people under 55 are diagnosed by age 55 is just mind-blowing. It's like we're sleepwalking into a health disaster! 
And it's not just about what we eat or how much exercise we do – there's this whole gut bacteria thing that I'm not even gonna get into... let's just say it sounds super complicated 
.
how did these people even get diagnosed with colorectal cancer over 100 years ago? didn't they have any meds or treatments or anything? 
also what's up with the E. coli theory? is it really possible that this type of bacteria just started showing up in our gut a few decades ago and then causes cancer? 
we need to make some serious changes in our lifestyle ASAP
