I think a lot of it is increase in diagnostic capabilities.
Ah yes, the significantly higher diagnostic capabilities of death by cancer
This article kind of made a mess of the numbers. At one point it suggests the mortality rate increased, but that’s not what the actual research shows.
From OG article: “Our study showed that the global morbidity of early-onset cancer increased from 1990 to 2019, while mortality and DALYs slightly decreased”
https://bmjoncology.bmj.com/content/2/1/e000049
The vast majority of the raw numbers increasing is because of the word population going from 5.3 billion to 7.75 billion in that same time. The next cause does seem to be diagnostic ability, especially when looking at what cancers saw the biggest increase.
So, correct me if I'm wrong, but the actual number when speaking relative to population growth would be:
180% / (7.75 Billion / 5.3 Billion) = 123.1%
So it's actually only a 23% increase, relatively.
This article is so misleading.
Yeah. The unfortunate truth about science news reporting is that usually it's not sensational, so they need to play things up for clicks and ad revenue. A lot of the time it ends up in somewhat misleading semi-truths like this.
That's correct.
?
I think the argument they're making is that detecting that a death is caused by cancer is probably not an advanced affair requiring new diagnostic technology.
Personally, I think it's an interesting question, given that it stands to reason that cancer, by the time it has caused death, should be pretty easily detectable in any sort of autopsy.
A post-mortem is not what most people think of when talking about cancer diagnostics.
Well, the article refers to both :)
I think you'd be right about the "number of diagnoses" statement in the title, but I think the discussion is about the deaths due to cancer, which have also increased and would not have as strong of a correlation for the reasons others mentioned
But that's directly related. People used to die when "catching a cold". We call that lung cancer nowadays. Same thing with many other branches of cancer.
How many people are getting autopsies in rural Afghanistan or India?
Even in the US, autopsies are not always performed. Ima quote WebMD because I'm bone idle:
Although laws vary, nearly all states call for an autopsy when someone dies in a suspicious, unusual, or unnatural way.
Many states have one done when a person dies without a doctor present. Twenty-seven states require it if the cause of death is suspected to be from a public health threat, such as a fast-spreading disease or tainted food.
According to a 2012 DOJ report, only 8.5% of US deaths result in autopsy.
I mean sure. But the data is likely comparative and can be looked at just within countries that have been getting autopsies since the 90s.
And what is the stat in those countries?
A lot blaming pfas and microplastics, but obesity is up too. According to the cdc that increases risk significantly in 13 types of cancer. Of course now looking up some are linking pfas to weight gain so maybe you guys are right!
There needs to be a lot more studies on obesity and why it's gone up so much. I don't buy the "more sedentary lifestyle" argument. Our mobility hasn't changed THAT much in the last 50 years, at least not enough to explain the absolutely skyrocketing cases of obesity.
There's a big link between poverty and obesity. People in poverty tend to be more active due to more physically demanding jobs, so it feels like the cause has to be from cheap food. While a lot of people might immediately look to high fructose corn syrup, I'm not sure it's that simple. Obesity rates are rising even in places that don't use HFCS in everything. I wouldn't be surprised if there was some additive or preservative that started to get heavily used in the last few decades that's had horrible, unintended consequences.
Additives or preservatives aren't likely to be the core issue. At the end of the day, by far the most significant factor for weight change is calorie intake vs expenditure. The new drugs like Semaglutide fundamentally work by significantly suppressing hunger and increasing satiety, for instance. I'm not sure what the precise data looks like, but in general, people are less social, go out less, spend a lot more time sitting on their phones or computers, and are generally a bit more stressed. All of the is going to contribute to eating more and moving less.
There's also a big link between lack of sleep and both obesity and cancer (and dozens of other health problems).
Western society has glorified not getting enough sleep as though it makes you manlier or better in some way. It doesn't. It just makes you die sooner.
We've moved to an "always on" society with the proliferation of the internet. With this comes disrupted circadian rhythms and even more reasons/excuses to not follow a regular or beneficial sleep schedule.
Pfas and micro plastics cause hormonal issues that can result in weight problems.

And obesity is only going to increase since all the grocery overlords have jacked the costs of everything through the roof while their prepackaged boxes of sodium and fat mush seem to be the new staple for everyone.
Don't forget sugar. I've recently visited the US and their bread (if you can call it that) could easily be classified as cake where I'm from.

I stopped eating breads tbh...they are just horrid for you.
I wonder how much of this is actually just the result of better detection and screening processes. Not saying it's not a problem, but if it's just because we're getting better at spotting these things early it might actually be a good thing?
Plastics, PFAS, pesticides, chemicals, radiations, all is contaminated not only what you eat but also what you breath. What a surprise !
Between cancer and Alzheimer’s getting old sucks.
Its the plastic blood
Probably a range of synthetic chemicals we've been polluting the natural world with for the last century, especially over the last few decades.
Plastic best be mindful and leave room for the PFAS to join in on the fun!
I always wanted to be stretch Armstrong.
A lot of these people were exposed to unregulated toxic shit in their youth
I only read the headline and not the article, so I'm not sure if this was mentioned. Would the main cause be from melanoma caused by UV? Melanoma rates in Australia went through the roof when we had that big ozone hole above our country.
The main suspected causes mentioned are poor diet, alcohol, tobacco, physical inactivity, and obesity
well shit.
Plus side, these are factors that can be managed!
Even if it's not exactly fun to.
had that big ozone hole
Not sure if it still reaches Australia but we've still got the ozone hole here in NZ - and apparently cancer season is starting early this year thanks to climate change and water vapour from that Tongan volcano last year!
