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.
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.
Wife and I both had diverticulitis resulting in resections under 40. She had no family history, I did. Still crazy
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.
