Over the past 10 years, rates of colorectal cancer among 25 to 49 year olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina.

The investigation’s early findings, presented by an international team at the Union for International Cancer Control (UICC) congress in Geneva in September 2024, were as eye-catching as they are concerning.

The researchers, from the American Cancer Society (ACS) and the World Health Organization’s (WHO’s) International Agency for Research on Cancer, surveyed data from 50 countries to understand the trend. In 14 of these countries, the rising trend was only seen in younger adults, with older adult rates remaining stable.

Based on epidemiological investigations, it seems that this trend first began in the 1990s. One study found that the global incidence of early-onset cancer had increased by 79% between 1990 and 2019, with the number of cancer-related deaths in younger people rising by 29%. Another report in The Lancet Public Health described how cancer incidence rates in the US have steadily risen between the generations across 17 different cancers, particularly in Generation Xers and Millennials.

    We’ve poisoned our planet for the last 100+ years and now we are dying off slowly from the fruits of our labor.

    The irony.

      if that were the case, you’d expect more cancer in older people as well, not just young people.

      Cancer deaths are consistently declining in the US. American Cancer Society’s 2023 report

      Despite the pandemic, and in contrast with other leading causes of death, the cancer death rate continued to decline from 2019 to 2020 (by 1.5%), contributing to a 33% overall reduction since 1991 and an estimated 3.8 million deaths averted.

        that could also be because less people are being tested as a result of medical burnout, faculty reductions, or other more lethal illnesses taking it’s place.

        just because it’s declining generally doesn’t mean it’s actually going away.

          more likely the opposite, we see higher “incidents” because of improved detection and reporting. meanwhile deaths decline because of improved treatments and prevention.

    Better back that colonoscopy screening up earlier then. I think it’s recommended at age 45 in the US, but I’m guessing insurance won’t want to cover screenings at 5-year intervals for an extra 20 years because money, dear boy.

      It was recently dropped from 50 to 45 in the US. Was that also done for other countries?

      Regardless of improved detection, the most likely explanation is increased obesity rates, which is covered in the article.

      Last time I pointed this out, the toxin and micro plastics people blamed chemical exposure for increased obesity. They don’t want the Boogeyman to be a fat guy.

    I bet it ends up being caused by something far more innocuous than any of the first guesses that come to mind.

      The nightmare scenario is it being caused by something even more insidious and omnipresent than microplastics. The second nightmare scenario is microplastics.

        Most likely it’s caused by boring things that we already know about. But behaviour change is hard. Meat, smoking, drinking, obesity.

    Obesity tracks with this. Maybe not the direct cause, there might be some underlying cause for both, but excess fat absolutely does increase your risk of cancer. I’m pretty sure being big in any way does - if there is more of you, more cells, more chance of mutation.

      These kind of cancers are the sad kind where they’re readily treatable if you catch them early. But if you put it off and wait too long, you can literally die anally and painfully from your procrastination.

      All you’ll likely feel is pain and regret for the remainder of your life. Not just for putting this off, but for all the other things you put off for “later” as the end rapidly approaches. Doesn’t sound great.

        Wireless communications radiation physically cannot cause increased mutation rates and this is quite well studied. Wireless communication operates on frequencies (for the most part) below 10GHz, which has wavelengths measured in centimeters and meters. The biggest wave that can impact human DNA is UV which has wavelengths measured in nanometers - orders of magnitude of difference. So no, wireless communications are super unlikely to impact cancer rates.

      Yes, in particular the non-stick forever chemicals known as PFAS (aka Teflon and its precursors). The same chemistry that makes these plastics so non-stick also makes them resilient to being broken down chemically in our bodies. And the more the government tries to regulate them away, the more the industry plays whack-a-mole with modifications to the formula. It’s the designer drug problem writ large!

    Could it be the single use micro plastics….

    Older people have cancer and a lot of doctors just call it aging. That’s how common it is. It’s normalized. Now that the younger are catching up they are suddenly concerned that this is a problem.

    Recently I went to Seattle’s children’s museum and when it was about to close I found my self staring at the cosmic particle fog tank. It’s a tank that has low temperature evaporated alcohol in it which creates wisps of fog if highly energetic particles pass thru it. Well I didn’t know what it was until I started noticing the wisps and remembering a YouTube video in the device. It was like a wisp every 10 seconds. Suddenly this family passed by and the little 3 or 4 year old kid approaches the box to see what was in it. The thing lit up like a freaking Christmas tree. Like 10 wisps per second as soon as the kid put his hands on the side of the glass. I looked at him thinking, you don’t know, just live out your life in happiness kid.

              would be an injectable radiation therapy or a radiotracer for a PET or SPECT scan. afaik radioactive tracers aren’t used in MRI or regular CT scanning

                A radioactive tracer can be used in a PET/MRI scan, or a gadolinium-based contrast medium used in an MRI scan. But I think you’re right about MRI not actually requiring a tracer.

                  MRI sometimes uses a non-radioactive contrast depending on what you’re trying to get images of. MRI is probably the safest imaging modality, but it’s very expensive, kind of difficult sometimes due to how long it takes, and isn’t useful for every kind of imaging that needs to be done.
