Quackery?

"Nature Reviews Clinical Oncology" isn't usually quackery is it?

I think that a Journal of Medical Science, specialising in Oncology, might have something worthwhile to say.

Could it be the microplastics in our heart tissues? https://news.ycombinator.com/item?id=37067554
>One limitation of this study is that researchers did not have an adequate amount of data from low- and middle-income countries to identify trends in cancer incidence over the decades.

If they had this data, it could perhaps answer your question.

But I would say that microplastics do play a negative role.

I admit that the question was ostensibly rhetorical in nature, they're doing no good being there that's for sure :(
cellphones? imho our generation cigarettes. studies will point that radiation are not harmful until they are.
A hunch isn't science. Just because they're demonstrably harmful mentally doesn't mean they are physically.
You sound like my grandma lmao.

If it was cellphones it would be easy to spot as places where they are closest to (left/right hip, head) would be ones with increased cancer rates

If you actually look at how strong the radiation phones put out is, you'd realize there's basically no way.

The power is at a maximum 3 watts, and is usually measured in milliwatts if you're somewhere with excellent reception.

This is roughly on par with the amount of heat released while charging. Not fast charging mind you, charging with an old micro usb 5v charger.

Compare this to a radio station which can transmit tens of kilowatts of power. If radio waves could cause cancer, people who work at radio stations would be riddled with it, and radio stations have been around a lot longer than phones.

Your analysis doesn’t account for the inverse square law.

That is, wouldn’t we want to compare the radiant flux rather than the power?

You would yes, but I think you'll find that with with 4 orders of magnitude to play with the radio tower still comes out on top.

Also how much time do you actually spend with the phone against your head on any given day? A few minutes maybe. Someone working at the radio station is there for 8 hours.

My only point was that it’s misleading to compare power.

I don’t have an opinion on whether mobile phone usage is more or less likely to cause cancer than working in a radio station.

Is power the only relevant variable? What about wavelength?
A photon emitted from a mobile phone antenna has about five orders of magnitude less energy than a photon of visible light. It just isn't plausible that such a relatively small number of relatively low-energy photons could have a meaningful impact on human heath, considering our overall exposure to electromagnetic radiation.

https://en.wikipedia.org/wiki/Electromagnetic_spectrum

Sure. 3 Watts of gamma rays will do a different job. But a cell phone works in the microwave range - visible light, infrared, UV are all more dangerous - and the sun will blast you with 1 kW on a nice sunny day.

Cell phones are not the problem (well, not the microwaves at least).

E = hf

You can measure the energy of one photo using this equation.

Microwaves at 2.45 Ghz = 1.6243499999999998e-24 eV

Gamma radiation at 3 x 10(19) Hz = 1.9889999999999998e-14 eV

So about 10(10) more energy per gamma ray photo or about 10 billion times more energy.

It isn't necessarily that simple. I once came across a study that claimed that while the class of electromagnetic radiation associated with cell phones isn't able to cause a cancer mutation itself, there were indications that it could have the effect of suppressing the immune system's ability to fight cancers from other causes.

I'm sorry I have lost the paper when upgrading my home PC over the years. I too would like to read follow-up studies, if there are any. If anyone reading this knows what paper I am talking about, please do reply.

> imho our generation cigarettes

Smoking prevalence has reduced dramatically in the past fifty years. If anything that should be a declining reason over the course of the last century.

I think they meant that cellphones are our generation's equivalent of cigarettes.
You clearly didn't bother to read the article, did you (ie trend started in 90s if not earlier, also many of those are directly digestive system).

Is anybody actually surprised? We eat crappier and crappier food, even basic stuff like vegetables is heavily modified, pumped directly with insecticides, herbicides, and drains from nearby farms that could contain literally anything. Most fish went from very healthy to questionable at best. We move much much less. We have more but are less happy and have more stressful lives. Race to bottom puts sugar into all processed foods just to make them more addictive. Microplastics. BPAs. PFOAs. And so on and on. The idea that somehow this would have 0 negative effect is a bit naive, no?

> studies will point that radiation are not harmful until they are.

Smartphones might genuinely be a thing future generations will look at asking "what were you thinking?", but this argument is completely moot, as it could be used against literally anything.

Studies will suggest that electricity is not harmful until it is. Studies will suggest that freedom of speech is not harmful until it is. Studies will suggest that touching grass is not harmful until it is.

Maybe there are different causes in different zones.

For example, ozone layer hole sure did increase the cases in South America.

In North America, maybe the industrialization and bad diet.

I doubt it’s related to this, but I do wonder if we’ve passed peak robustness in the human genome with modern medicine and technology insulating it from the crucible of natural selection.
There is plenty of natural selection going on. A large amount of people will not have kids this decade due to anti-natalist propaganda and wars (Chiraq, Ukraine, Africa, etc.). Each time someone does not have a child, there is a future fractal effect of their decision which does not occur. Namely their kids won't have kids, etc., for all possible future generations. So in essence each couple that has more than two kids on average moving forward through the future has a massive impact on the future population. Also there are huge changes to the global genome composition as a result of mixed race breeding. It was much more rare before 1980. So nobody can claim that peak robustness has been reached unless you can specify some testable metric for it.
What anti-natalist propaganda?
Do you live in Western society? There is a prevelant point of view that it is wiser to have children later, because otherwise it hurts your career.

I am not saying this is wrong. It does, though, decrease the number of kids we have.

That's not anti-natalism.
It also doesn't sound like propaganda.
Agree. Anti birth would be my opinion: ask yourself, would the world be better off with the current amount of people in it or more, or with a small percentage fewer? People around you have kids anyway, that much is evident. So imo it's selfish, wanting entertainment or an excuse to meet other adults and make friends again or receive personal care at old age or whatever it may be. (But I also respect other people's opinions on this, and I don't bring this up with parents/pregnants (already too late anyway), just my own philosophy.) I haven't heard this be an official opinion of any country recently, let alone western society as a whole...
And later pregnancy is more risky for both mother and child. To resolve this, socialist policies need to be introduced, decisively anti-capitalist policies that will theoretically harm a country's GDP (because it encourages people to not participate in the labour pool).
What socialist (so-called) policies benefit older mothers more than young ones?
Example:

https://www.theguardian.com/environment/2017/jul/12/want-to-...

The propaganda part:

"By far the biggest ultimate impact is having one fewer child, which the researchers calculated equated to a reduction of 58 tonnes of CO2 for each year of a parent’s life."

If you look into the source study:

https://www.biologicaldiversity.org/programs/population_and_...

Specifically at Figure 6, you'll note that those 58 tonnes refer to the peak of the "carbon legacy curve".

As an environmentalist I'm indignant that such an association was ever drawn.

For one: who says the next generation will have nearly the same carbon footprint? That's already not the case currently and the trend is clear.

That is stretching the definition of nature to anything outside an individual’s own body.
Modern medicine is barely a generation old.
Right: if you go back two generous human lifespans there is almost nothing.

I always have two specific lifespans in mind when I say this: my late father’s and that of a man he admired and studied under in his youth: Alexander Fleming. Go back before Fleming’s birth in 1881 and you are in the medical dark ages in some respects.

The NHS is really only a human lifespan old.

there was a popular medical textbook, reprinted well into 1920s, that still recommended bloodletting.

(and not in some sensible "did you know actually leeches are still useful for healing wounds?" way. just old school bloodletting.)

I get what you're saying and it doesn't make a material difference, but a lifespan and a generation are quite different. My grandpa was born in 1928, when penicillin was discovered. There's a picture of him holding my brother's grandson. That's five generations in one lifespan, four of which could have been meaningfully impacted by the availability of a general antibiotic.

Now are we going to start observing the influence of that on the human immune system in four generations? No. Forty? Maybe a little bump in the noise floor. Four hundred? Almost certainly yes.

Yes, you're correct of course -- I'm just concurring that medicine is really really new.
True but if you could somehow chart 'robustness of homo sapiens' over time, it seems plausible that modern medicine and technology has and will continue to influence it. Little things like food allergies that may have a genetic component seem to be able to persist now that we have effective mitigations for them.

As a counterpoint, transportation is a major feature of modern technology that has resulted in a lot more mixing of heritable traits that could previously have been regionally isolated. That's probably a net good thing for robustness.

Kind of pointless mental exercise but something I ponder on occasionally.

Article doesn't quantify how much "dramatic" is. While I read the source (it's not in the abstract either), anyone wants to guess what percentage it is that they call dramatic?

(Of course, more than zero is worth looking into, I'm just curious if the alarmism is warranted.)

Edit: citing my comment below, the best info I could reasonably find on mobile (I'm now 35 minutes into answering the question that the stupid headline raised) is:

> - it's about +5% as a very rough estimate of an overall average.

> - The highest I see is typically in Korea, up to about 20%, but often (for different cancer types) also around 5% or even negative in one case. (Keep in mind that 20% more may be peanuts if the original chance was one in a million. Is thyroid cancer common?)

> - USA average is more like 2% I'd guess, with maxima of like 5%.

> - Sweden is negative as often as positive, maybe +1%? Large error bars, though.

> Dramatic? You be the judge, but the original authors never used that word

Neither does the conclusion. Nor is there an easy to read chart that shows it.
Yep. The conclusion just says "has increased", and that's unfortunately not followed by a "by X" or any other quantification.

I skimmed the whole article by now and am reverting back to the 260 data points (10 counties × 13 cancers × 2 genders) shown on page 3 to do it myself. Currently I'm wondering how to consolidate into a single number (on mobile). Should I eyeball guesstimate the percentage for each country, look up their population, and do a weighted average or what would be a good way to do this? Ideally I'd also compute the lower and upper bounds with the 95% CI values... Hmm

Edit: ah it refers to a supplementary table, not shown in the paper, for the original data. So I don't have to eyeball it. Downloading that. Let's see

... what did I expect. 4 pages filled from top to bottom with numbers in narrow table cells. Text is not copyable, maybe due to the mobile pdf reader idk. But I'm going to draw the line here

Eyeballing that thing on page 3 of the article:

- it's about +5% as a very rough estimate of an overall average.

- The highest I see is typically in Korea, up to about 20%, but often (for different cancer types) also around 5% or even negative in one case. (Keep in mind that 20% more may be peanuts if the original chance was one in a million. Is thyroid cancer common?)

- USA average is more like 2% I'd guess, with maxima of like 5%.

- Sweden is negative as often as positive, maybe +1%? Large error bars, though.

Dramatic? You be the judge, but the original authors never used that word

Is there a meaningful way to boil it down to a single number?

Like for instance, in wealthier countries, rates of esophageal cancer dropped. Maybe because of better drugs for treating reflux. How is that expected to relate to rates of kidney cancer in poorer countries?

So we are getting 5% better at detecting cancer every 10 years? Sounds good to me!
Any increase in cancer rate in a population is dramatic.
Note the part where I said

> (Of course, more than zero is worth looking into, I'm just curious if the alarmism is warranted.)

>They couldn’t precisely measure what proportion of this growing prevalence could solely be attributed to screening and early detection. However, they noted that increased incidence of many of the 14 cancer types is unlikely due to enhanced screening alone.

I hope the majority of the increase is due to enhanced screening. Anything that gives us more time to solve the cancer problem!

"dramatic rise" cool... By how much? Am I the only one tired of super dramatized articles with no facts or data at all?
It’s sad that even an institution like Harvard is succumbing to this kind of sensationalism…
Is this meant to be satirical?
No, not really. Are they usually posting stuff like this?
Between 0% and some number…

>They couldn’t precisely measure what proportion of this growing prevalence could solely be attributed to screening and early detection. However, they noted that increased incidence of many of the 14 cancer types is unlikely due to enhanced screening alone.

> Between 0% and some number

Not exactly! Many of the cancer rates in many countries were actually below 0%! Dramatic :)

Some number need not be positive ;)
Flag it and move on. Articles like this need to be moved to the waste bin and we can all collectively make that happen.
I'm basing this on absolutely no specialized knowledge or research of my own, but it has to be processed food.

Like it just has to be, in about 2-3 generations we've just utterly abandoned tens of thousands of years of fairly consistently eating variations on plants, cooked animal flesh, and fermented variations of the same, in favor of a staggering array of highly pre-processed chemicals.

The results are obvious and instantly visible everywhere: massive increases in obesity, chronic conditions like fatigue and depression, and so on. We're poisoning ourselves.

The only other contender that comes to mind is being constantly surrounded by and consuming plastic. Which is basically another thread on the same basic issue of our industrialized diets.

Hey maybe I'm wrong. But probably not right?

Throw a dart at a barn and you'll hit something that we're doing which we didn't really do until 150 years ago.

But processed food is a likely culprit.

There are a lot of PFAS chemicals and Microplastics just about everywhere and this is just a start.
What is the link to cancer?
Aye. there are certainly reasons to think that PFAS is a bad thing and having an impact, but given how insanely widespread it is, what is the real impact?
The mass rollout of mRNA treatment was not mentioned in this article. I wonder if they tried to control for "sleep deprivation, increase in alcohol consumption" to find out if that's correlating. I'd be even more interested to see what happens if they control for mRNA treatment status.
I'm not familiar with any use of mRNA based treatments before 2012, are you?
Dramatic rise in cancer diagnosis.
How many people die without the cause of death known?
For all 14 cancers in question? Likely more in 2000 than in 2012. Don't know by how much and not saying they didn't control for that, just answering your question...
A quite large number! Not to mention those who died if other causes but hadn’t had a cancer diagnosis yet.

But we’re talking about cancer incidence not deaths. Which—like the “rise” is autism—is quite likely due to early detection & patient awareness than external factors.

Couldn't the reason be also that people survive or simply don't get affected by other illnesses anymore?
Could that be the cause for the numbers, if the numbers are only about people under the age of 50? Also in 1900, afaik it was very normal to live till 50.
Yeah, maybe don't allow shit like aspartame or TiO2 (read banning of it in Northern Ireland after it has been happily used in food) to go into production before establishing more concrete evidence for its safety then.

Same goes for parabens in cosmetics (read banning of specific parabens in the EU), you can't act surprised that some turn out to have an agonistic effect like estrogen and be potentially carcinogenic in women and accumulate in vitro when you throw it at the market with little real safety data. The biggest joke I've read is a recent-ish review concluding that consumers can cross the maximum recommended daily exposure with just a few cosmetics containing specific parabens because it was underestimated how much consumers use.

(comment deleted)
We know that obesity and sedentary lifestyles have become vastly more common and significantly increase the risk of many cancers. We know that diagnosis rates have greatly increased because of widespread population screening, more sensitive diagnostic tests and improved access to healthcare. It shouldn't particularly surprise us that there has been a small but steady increase in the rate of diagnosed cancers in recent decades.

We should be very cautious about immediately jumping to the conclusion that something we don't like (plastics, mobile phones, vaccines) is probably terribly carcinogenic despite the lack of causal evidence.

Included in life-style factors is also that people are eating more meat than ever before. While meat itself isn't unhealthy, some ways of cooking and curing meat do introduce well-known cancer risks.

Some common plastics are also known cancer risks — if you heat them up or dissolve them, and inhale the fumes. Personally, I believe my hobby with synthetic resins and styrene (using solvent-based "glue") is what could have caused the B-cell lymphoma that I am suffering from.

I say "cancer risks" because it is not either/or: It is about probabilities. Cancer mutations actually happen often in the body, and the immune system is constantly fighting them. It is when the immune system loses that you "get cancer".

>> We should be very cautious about immediately jumping to the conclusion that something we don't like (plastics, mobile phones, vaccines) is probably terribly carcinogenic despite the lack of causal evidence.

Think it depends

If exposure is based on good evidence that it is safe, and/or personal choice is involved, then absolutely, e.g. Vaccines, RF.

However, when humans are being exposed to an environment outside that to which we are adapted to (usually because the market has been largely left to get on with it), e.g. plastics exposure, continuous traffic and aircraft noise, pollution, sugar loaded convenience foods, fast food rich environments, places that prioritise vehicle movement over humans etc.

Then in those cases its worth noting that historically they are good health outcomes, e.g. smoking, leaded petrol, alcohol, hydrogenated vegetable fat, DDT etc. In general there aren't that many animals that thrive in the long-term outside of their evolutionary niches. And personally as an Engineer I don't think waiting for the scientific process to fight its way through the vested interests to start doing something about things that are very likely problems is a sensible approach.

Should I be reincarnated, I try to be born in a country with a high death rate from cancer.

Coincidentally, they correlate with the countries that have a high life expectancy.

But beware, the average cancer mortality there has been decreasing for decades.

If you're unlucky, you might just die of old age...

This study specifically is about people under the age of 50
People sit 12+ hours per day (work, commute, at home) and eat processed foods.

Living literally the opposite lifestyle from the one our bodies are made for.

Not a surprise.

Our bodies were made for Africa afaik, and for outrunning prey across long distances using the revolutionary sweating method, and for having children at 14 years old. Anyone who isn't doing this can be argued to be unnatural.

I find this argument always very weird, especially on hacker news. Just because something wasn't made for X, doesn't that mean you can't or shouldn't use it for X? That's basically the definition of hacking in the hacker news sense of the word. By this logic, we shouldn't be taking any mode of transportation because we didn't evolve to sail, drive, or fly. Heck, we shouldn't be writing on the Internet, let alone writing at all!

Wouldn't it make more sense to argue the point itself, e.g. our bodies don't deal well with X because of Y, rather than citing historic evolutionary pressures?

> I find this argument always very weird, especially on hacker news. Just because something wasn't made for X, doesn't that mean you can't or shouldn't use it for X? That's basically the definition of hacking in the hacker news sense of the word.

Just because you can use your impact driver as a hammer doesn't mean its going to last if you use it like one. It doesn't seem contradictory to acknowledge that you can do all sorts of things, but some of those things are going to have varying levels of consequences.

There is a sense of optimism that I see in people that everything new is good. I had that same optimism for a long time. But so did people who were using leaded gas and xrays for fitting shoes. Now I reflexively don't trust anything that doesn't have a long history of successful usage.

Dramatic rise in cancer, dramatic rise in CVD, dramatic rise in infertility, dramatic rise in what next?

There’s more things killing you slowly. Look to stress as a major driver of these things as well. (I.e. Sapolsky’s work)

1. How dramatic? 2. Which cancers? 3. Could it be explained with decrease in other diseases, which leaves cancer as last illness. 4. Could it be explained with better diagnosis methods - are the cancers benign or malignant. Slow or fast growing?
Why is there never any chart in this kind of articles?
