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.

    Lead and Teflon have gone down since the 90s. I’d say it’s mostly plastic. Up and into most all of the 80’s everyone drank tap water and sodas/other drinks were all canned or glass bottles.

    Then around 1990 everyone started putting their drink in plastic. Then 15 years later for some dumbass reason, people started to buy and drink all their water out of plastic as well.

      Problem with PFAS and many other stuff is that it is accumulating in the biosphere. So while the new emissions go down, you still end up being exposed to more and more of them over time. They still get into the water and then into the plants and animals that you eat later.

      The largest contributor to the micro-plastics in your body is tire dust, though, it’s not new. More of it since the 90s, yeah, maybe there’s a threshold?

        Doesn’t really seem like there’s more plastic dust? But since this study looked at colon cancer, maybe inhalation plastic has less of a role?
