Distinct cellular and genetic differences in colorectal cancer in young patients

I wonder if the higher proportion of stromal cells in young tumors is a direct result of specific dietary components or gut microbiome variations rather than just inherent biology. The study mentions looking at how cell programs interact with diet and microbes, but it seems early onset cases often present with distinct inflammatory profiles in the colon itself before tumor formation.

It would be interesting to see if these long non-coding RNAs show up consistently in pre cancerous polyps in younger patients or only after malignant transformation. If they are elevated early on, that could actually help solve the diagnosis problem where many late stage cancers are found, assuming we can target them specifically.

The lncRNA is common in all CRCs but the stroma content in healthy tissue usually increases with age

Does this track differences between generations (i.e. environmental changes), or the age-related differences within a single cohort, or somehow both at once?

I'm 35. I had a preventative colonoscopy done (I had to insist). I payed out of pocket since these checkups normally start at 50.

Adenoma found and removed.

This is a type of cancer that is almost entirely preventable with screening. Get your tubes checked.

I'd rather die over having a tube up my ass, and I've seen my father die to this exact type of cancer.

I think its okay when you tell the doctor no homo.

Surely

I think you need to get the doctor to say it, not the other way round

not sure if that makes it better for you, but usually you are knocked out and don't know what is happening during the procedure. Much worse is the preparation starting days before with disgustingly tasting things that intentionally give you diarrhea (and maybe make you puke) to clear the path, and no food at all

People get a safe but vile-tasting laxative by default. If you don't have any known problems with your colon then you could ask for a faster-acting laxative that is easier to get down.

I have a condition, so I have a colonoscopy every year. Once I had found out about there being a fast-acting alternative, I've always chosen that.

I've never done it sedated. I prefer to watch the screen and and ask questions. I've found it quite fascinating, actually. The doctors and nurses have always been professional, focused on the colon: not the butt. There is absolutely nothing sexual about it. I've never felt pain: only some tension, and that's been because of gas (needed to get a clear view). It is perfectly safe unless your colon has some illness of some sort. The worst part has always been the prep.

I don't intend to disagree, merely to suggest that while doing the right thing one would be best off considering the potential aspects inflicted to themselves, in this case colonoscopy deaths are one in ten thousand from memory

I suspect that risk calculus depends on where you live.

Did you suspect you had a higher chance than general population? If so why?

Spacecosmonaut | an hour ago

Not really. I try to live a pretty healthy lifestyle. I work as a cancer researcher, so I have more contact with these data.
That's crazy. And you don't deal with wet lab I imagine, so just a freak occurrence.

Wow, did you have any kind of symptoms?
