It’s hard to detect in young people often causes no symptoms until later stages.

[–] Buffalox@lemmy.world 21 points 9 hours ago (4 children)

Suspected causes:

changes in the gut microbiome, obesity, lack of physical activity, and ultra-processed foods.

But research is lacking? For the most deadly form of cancer we have? WTF?
I wonder why alcohol isn't on that list? Are people drinking less alcohol to favor other substances?
Because AFAIK alcohol is determined to be a major risk-factor for cancer.

This topic is close to home for me, as both my grandmothers died of colorectal cancer. I've also been deeply interested in the topic of nutrition for a long time.

  • Cut alcohol.
  • Cut Ultra-Processed Foods.
  • Cut Red Meat
  • Increase fiber (especially soluble fiber).
  • Increase Fermented foods (get refrigerated or home fermented sauerkraut, not canned or jarred)
  • Increase foods high in antioxidants.
  • Engage in just moderate exercise.

(get refrigerated or home fermented sauerkraut, not canned or jarred)

..what? How is it refrigerated but not in a jar? I love sauerkraut, what are you talking about?

[–] discocactus@lemmy.world 3 points 4 hours ago

Canned is a verb as well as an adjective. The verb kills the microbiology that is useful.

[–] Zedstrian@lemmy.dbzer0.com 3 points 4 hours ago

I don't eat it, but I've seen it sold refrigerated in a bag.

[–] sidelove@lemmy.world 14 points 9 hours ago* (last edited 9 hours ago) (1 children)

I think they mean heat-canning/jarring, which sterilizes it and destroys a lot of the probiotics in it to make it shelf-stable. Room temp sauerkraut is still good for you, just not as good as the less-processed stuff that requires refrigeration.

[–] lennybird@lemmy.world 7 points 9 hours ago

Correct!

The probiotics (live, good bacteria) are effectively dead in these. You get some benefits due to the metabolites left over but it's less than ideal.

[–] Buffalox@lemmy.world 0 points 8 hours ago (1 children)

That's a very good list, doing a bit of that would be an improvement for by far the most people including myself.

Personally I never eat red meat, I always cook it first. 😜
Well now meat has increased in price, and they are packing it in smaller packages, so we have reduced it some.
I know we should reduce it more for many reasons, but meat is to us like the cornerstone of the meal everything else is based around.

Regarding fermented food, I'm not so sure the healthy gut bacteria from it is relevant very often, like AFAIK youghurt contains zero living bacteria from the process when sold.
And the same goes for most fermented foods. The thing we eat most of is sourdough bread, and the bacteria in that are probably all dead from baking it.
BUT there may be an issue of the fermentation prepossessing nutrients that are hard for us to absorb without the fermentation. Alternatively it may be that the good bacteria from fermentation help keep out bad bacteria.
I'm not sure what the actual evidence says on these issues, but sometimes it seems the evidence isn't entirely clear. Same with fiber BTW, AFAIK the results on fiber are mixed.
For instance bread with added fiber seems to have no benefit. But it's been more than a decade since I last read up on the issues.

I mean you know wrongly then. Live active culture yoghurt is everywhere. Maybe read something first and learn something interesting and then offer it up?

Probiotics - Health Professional Fact Sheet

[–] justsomeguy@lemmy.world 7 points 9 hours ago (1 children)

Most deadly in relatively young people. If this was a boomer problem there's be more research.

I find the list of suspected causes quite vague. What bothers me most is the warnings about processed food. So much food is considered processed but which processes/ingredients exactly are causing harm?

What's worse, a bag of chips or a can of tuna? Nutritionally the tuna wins but where is it on the ass cancer scale?

[–] Buffalox@lemmy.world 3 points 8 hours ago

Chips are normally considered ultra processed, they have additives you would never find in a kitchen, and it's extremely high in calories, and at the same time extremely low in actual nutrients.

[–] PlantJam@lemmy.world 7 points 9 hours ago* (last edited 9 hours ago) (1 children)

A study last year suggested a link between long distance running and colon cancer, so even increasing activity may not save us.

Another study seems to hypothesise that the cancer risk may be related to reduced blood flow to the gut.

[–] Buffalox@lemmy.world 6 points 9 hours ago

Wow, that first part is very counter intuitive, as running is usually associated with massaging your gut, which should improve healthy digestion!

Several years ago, Dr. Cannon noticed a disturbing trend: multiple ultramarathoners

Ah that explains it, ultra marathon is definitely not healthy, such extreme prolonged exertion can also have a negative impact on immune defense.
Decreased immune defense means increased infection rate, and increased infection rate is directly correlated to increased risk of cancer.
I suppose in some sense our digestive system is a type of constant infection, which could be the reason it shows up there.

[–] GreenShimada@lemmy.world 5 points 8 hours ago (1 children)

One person I know of died from it as the result of growing up on a Superfund site.

I feel like Millennials are like honey bees. In 30 years someone's going to figure it out and say "Ohhhhhh, hey guys? Yeah, it was when you combined hot dogs, sour patch kids, and specifically strawberry crush within a 36 hour period between ages 5 and 22, and are then got COVID and were exposed to microwaves after that to activate it all."

[–] Buffalox@lemmy.world 2 points 8 hours ago

I think it may actually be pretty simple when we figure out the main reasons, but there may not be one single reason, in fact I consider that highly unlikely.
Most likely half of it is about undetected inflammations and alcohol/sugar.

[–] jordanlund@lemmy.world 12 points 8 hours ago (2 children)

So, a couple of things... Fighting stage 2 colon cancer right now.

6 months ago they found 17 polyps, 2 were an unusual size, 20mm and 30mm.

Rule of thumb is "Anything more than 5 or anything bigger than 5mm."

But - not cancer. Repeat in January. 6 more polyps including one that's 20mm and stage 2.

So it went from 0 to stage 2 in 6 months. I'm going to lose my entire sigmoid colon and all the lymph nodes around it for biopsy.

If the cancer has spread to the lymph nodes, that's stage 3 and I'll have chemo, but we won't know until after the surgery.

Don't sleep on this. My symptoms were anemia and tiredness all the time.

Yes, colonoscopy prep sucks. I had to drink 4 liters of fluid, wait 6 hours, and do it all over again. I lined up 10 glasses and drained one every 12 minutes for 2 hours.

But - you can mix in gatorade powder so long as it's not red or purple. 😉

March is colon cancer awareness month, wear blue!

How old are you? Do you mind sharing?

There's also a version of the prep that is only 2 liters. Its more concentrated, but I can do that easier for me than the 4 liters.

Another vote for getting colonoscopy screening. I had two precancerous polyps they found. Confusingly, precancerous doesn't mean they are cancer, but rather the type of polyps that turn into cancer. Both were removed during the procedure. With that there's no more actions or risk needed except a followup colonoscopy in 3 years. If they found no polyps its a followup in 10 years.

Also if its a colonoscopy screening, and because of the ACA, the entire procedure is covered by insurance as its a wellness screening. If they are doing a colonoscopy because you're reporting problems, then its a "diagnostics" colonoscopy and you can get charged for it. The price tag on mine was slightly over $2500, but was 100% covered because it was a screening. Get your colonoscopy before you have problems and spend your $2500 on something else you want in your life!

Call today and get an appointment for this. When I called the soonest appointment was about 5 months out. Call today to get yours booked.

We lost a family member to colon cancer. She was 34 years old.

Don't put this off. Get it done, people.

The future is an AI powered dildo or buttplug to detect this. With a subscription of course.

But they can use the Dyson extractor to remove it for $68,000 and disposable fee which you can work off in the protein fields.

People put anything up there. Just have a little color-changing paper strip at the top of anything remotely oblong and the ER doc can give a quick read when removing the object.

I am convinced I'll be one of them (genetic predisposition). I'm gonna get killed by my own ass. Which in a certain way is incredibly on point for me, but I digress.
