Also, in a country that grew by approximately 10 Million people in the same span.

Probably got older too - are brain tumours linked with age? If this chart is accurate, 3.5 years older: https://www.statista.com/statistics/275394/median-age-of-the... They really should have looked at rates by a given age.

Yes, with an age distribution, one can ask if certain ages tend to be higher rate users of early-gen cell tech, which used much more power.

"They analysed 79,241 malignant brain tumours over 21 years, finding that cases of GBM in England have increased from around 1,250 a year in 1995 to just under 3,000." ~2000 new cases per year in a country with 53 million people? I'll take my chances. I'm fascinated how people obsess over the unproven and ultimately minuscule health risks associated with using a cell phone or drinking a glass of wine or eating chocol…

I'm fascinated about casual dismissal of actual problems justified by the fact that other problems exist. I'm not panicked by this issue, but I think there's something there. I play cards with a bunch of neurosurgeons - every one of them has professional concerns about cellular and bluetooth usage, and 4/6 expressed those concerns to me individually about my AirPods.

Shouldn't smartphones, if they do cause cancer, cause a much larger spike in the hands or pocket area?

I sure have my phone adjacent to those parts of my body a whole lot more than my head.

> I don't think it's typical to make direct contact with a cell phone for an hour at a time. Do you have any family who live more than 30 minutes away?

That's not how I meant it. I don't think it's typical of phone calls ; it is certainly common among people who make phone calls. Also, both qualifications in that sentence are important - not only "an hour at a time", but "direct contact". I have been on long calls at work with a landline/VOIP phone and found my ear hurts after a while with the earpiece resting against my ear. So I know that when my ear does not hurt…

I'd say long conversations are a pretty common thing for me if I'm actually bothering to make a phone call.

I wonder how many people hold their heads close to a running microwave while they are watching to see if something is overheating...

They probably don't do that making direct contact between their heads and the machine for an hour at a time. Seems like a bad comparison.

When I'm just standing near my running microwave, bluetooth will totally drop out and WiFi will degrade so even with shielding it must surely be radiating a lot more than a phone. Haven't payed attention to how the LTE signal is affected though.

It’s not typically adjacent to those body parts while emitting a steady stream of radio waves. Even if it remains away from your head and near those other body parys during a call, there’s no a tube (that may channel the radiation) from the phone leading internally like the ear canal.

You also expect the number of identified cases to increase as we improve detection methods and find tumors earlier.

Is this actually likely to have a notable impact on the statistics? My understanding is that cases diagnosed later or discovered in autopsy will contribute just as much as cases diagnosed early. Assuming that such tumours aren't routinely missed in autopsies. I imagine improvements in early detection may result in a temporary increase due to the shifting phase of detection, but this wouldn't account for a doubling ov…

1) Most people aren't autopsied upon death, autopsies are only performed in limited circumstances. I don't personally know of a single person whom died who an autopsy was performed on.

2) The article is vague and short but "cases of GBM in England have increased from around 1,250 a year in 1995 to just under 3,000" almost certainly refers to diagnosed cases of GBM, not including incidentals found in autopsies.

Mobile phones create much more radiation while on a call just as people tend to be holding the phone to their head while on a call.

It's not clear to me that it's a bad comparison for several reasons. (a) I don't think it's typical to make direct contact with a cell phone for an hour at a time. Most calls I make are short and I don't actually hold it touching my ear. That does depend on the noise level though. (b) Microwaves are much higher power. (c) Microwaves may be constructed to looser tolerances regarding shielding. Yes, microwaves are diff…

Microwaves may be constructed to looser tolerances regarding shielding. How? A cellphone literally can't shield its radiation, otherwise it wouldn't really work.

Cellphones are designed to shield your head from radiation, and instead direct transmissions outwards away from it. There are legal limits on the radiation absorbed by a human head while talking on the phone https://en.wikipedia.org/wiki/Specific_absorption_rate#Mobil...

So basically yes, phones do have shielding (on the head side only)

Pretty sure this is complete B.S considering the view of talking on the phone millenials and younger have. Like, there are literal memes about one being horrified and the sound of a phone ringing, which to me seems like a good indicator that we're talking less on the phone, so why would brain tumors increase?

I tried to find some statistics on Google, the statistics are all over the place but they all still show far far higher rates of making voice calls than I would have predicted (numbers look something like: 20% of time on phone spent talking, 1 hour a day spent talking, average 10 calls per day, even for teens - for the last stat, teens made more calls than anyone)

You are totally not right. 2000 new cases in a country of 53 million people is huge. Remember that brain cancer is nearly always fatal. Suppose it happens in the average age and the life expectancy is 80, so it cuts life expectancy by 40 years. If 2000 people per year contract it, it means 160K people overall, cutting their life expectancy by 40 years, meaning 6.4M person-years of lifetime cut. Or 1.5 months per person.

1.5 months of life is huge, this is only ~1 order of magnitude more than the smoking takes nationwide, and only a few times more than the drinking does. Probably more than any illegal drug does, taken separately.

So if this study is true, it will definitely put mobile phones among top 10 preventable causes of death.
